How to properly prepare the trimmer mix

Grape processing

The vine is sprayed in the spring with a 3% Bordeaux liquid (at the rate of 1.5 liters per 10 square meters of planting), and during the growing season, more gentle preparations without copper are used, since copper sulfate can inhibit the growth of young shoots and reduce the quality of grapes.

How to make 1% Bordeaux liquid

To prepare a 1% Bordeaux mixture, take 100 g of copper sulfate and 100-150 g of lime, dissolve the vitriol in 1 liter of hot water, and lime in 1 liter of cold water (in separate containers). As in the previous case, bring each solution to 5 liters, then strain the milk of lime and add copper sulfate to it.

Bordeaux liquid is poorly stored (no longer than a day), so use it immediately after preparation. In addition, please note: the finished mixture must not be diluted with water.

Bordeaux liquid. how to properly prepare and use

Processing of pear, apple, quince

In early spring, 1-2 treatments are carried out with a 3% solution of Bordeaux liquid, and during the growing season. with a 1% solution. at the rate of about 10 liters of the drug for an adult tree and about 2 liters for a young plant. No more than 6 treatments with Bordeaux mixture are carried out per season. For strong and healthy trees “blue spraying” is carried out every 3 years.

Ornamental trees and shrubs are treated with Bordeaux liquid in the same way. Since they are not harvested, they are re-sprayed with a 3% solution in the fall.

Adding an article to a new collection

Bordeaux liquid is the most popular fungicide that summer residents have been using for plant protection for many years. But for the treatments to be beneficial, this drug must be properly prepared.

Bordeaux liquid is a mixture of a solution of copper sulfate (copper sulfate in the form of a bright blue powder) and slaked lime (milk of lime). A solution of Bordeaux liquid can be safely called a universal drug that helps in the fight against fungal and bacterial diseases of various plant species.

In addition, copper, which is part of the Bordeaux mixture, is a trace element necessary for the proper development of plants. Copper deficiency is observed in peaty and acidic sandy soils. Crops grown in unfavorable conditions lag behind in growth, their leaves suffer from chlorosis. In this case, the treatment with Bordeaux liquid not only protects the plants from diseases, but also provides them with additional nutrition.

Bordeaux liquid is a mixture of lime and copper sulfate

Berry bushes processing

Gooseberries, raspberries, currants and strawberries are also sprayed with a 3% solution in early spring. This helps protect shrubs from leaf blight. During the growing season, 1% Bordeaux liquid is used, while no more than three sprays are carried out during the season. For 10 square meters of plantings, about 1.5 liters of the prepared mixture are consumed.

Rules for processing plants with Bordeaux liquid

Bordeaux mixture is used to combat fungal diseases of apple and pear (scab, fruit rot, leaf spots, rust), cherries, plums, cherry plums (gray rot, monilial burn, coccomycosis, clotterosporia), as well as with common diseases of berry bushes, grapes and roses (anthracnose, septoria, mildew, stem cancer, infectious burn).

In the spring (during the swelling of the kidneys) and late autumn (usually in November), a 3% solution of Bordeaux liquid is used. This helps to kill fungi and bacteria before and at the very end of the growing season. This procedure is called eradication spraying. The rest of the time (in late spring, summer and early autumn), 1% Bordeaux liquid is used: it is abundantly sprayed on plant leaves.

Stone fruit crops (plum, cherry plum, cherry, sweet cherry, apricot) are very sensitive to treatment with copper-containing preparations, therefore they are sprayed only in early spring and late autumn.

Plants are processed exclusively in dry and cool weather, since at high humidity the drug can cause leaf burns.

When processing, it is necessary to moisten the plant abundantly and evenly so that the solution flows down the branches and trunk, penetrating into all the cracks in the bark, since a large number of pathogenic microorganisms accumulate there. Properly carried out processing protects trees and shrubs from diseases and pests for a month.

Stone fruit processing

Cherry, sweet cherry, plum, apricot, peach are sprayed once before bud break with a 3% solution of Bordeaux liquid. Then, during the growing season, 2-3 treatments are carried out with a 1% (maybe even 0.75%) solution. 2 liters are spent on a young tree. preparation, and for one adult. about 10 liters.

Oil selection and fuel mixture for lawn mowers

So, have you finally become the owner of a petrol lawn mower or lawn mower? And your imagination is already creating images of how you courageously cope with the dense grass. However, the dream of a “perfect lawn” remains a dream, when the question involuntarily arises: what oil to use and what are the proportions of mixing it with gasoline?

You can find a lot of information on the correct preparation of the fuel mixture on the Internet. This topic is actively discussed on forums and other thematic resources. But, despite such an active discussion, there are many inconsistencies that have to be dealt with.

It doesn’t really matter what technique is used, it could be a lawn mower. lawn mower or chain saw. they are united by one. two-stroke gasoline engine. Unlike the 4T, it does not have an oil sump. To feed it, it is required to prepare a special fuel mixture consisting of gasoline and oil. The resulting liquid is fed directly to the engine (carburetor). During use, all actively working parts are thoroughly lubricated, contributing to trouble-free operation under all operating conditions.

Lawn Mower Engine Oil

Depending on the chemical composition, lubricants are divided into the following main groups:

Mineral. They are made on the basis of oils obtained from petroleum distillates. They are characterized by high viscosity and require frequent replacement. The material is intended for low-power appliances with an air-cooled system. Recommended for warm weather.

Semi-synthetic. They represent a kind of “golden mean”. They are based on a mixture of mineral and synthetic oils. A similar lubricant can be used in 2T and 4T engines, gardening and other equipment with air and liquid cooling.

Synthetic. They are made on the basis of special synthetic components containing esters. They are characterized by low viscosity and long service life. They can be used all year round, regardless of temperature conditions. Ideal for challenging heavy duty equipment with constant variable performance.

Any two-stroke oil, due to its 20% solvent composition, mixes well with fuel and has the feature of complete combustion. Their second characteristic feature is the color, which can be green, red or blue. Of course, this does not mean that some lubricant is better, but some worse. This is done solely so that it is convenient for the user to distinguish oil from pure gasoline.

Classification of engine oils:

The required parameters of oils for 2T engines are prescribed in the requirements of API TC JASO FC, API TC JASO FC ISO GD and API TC JASO FC E-GC. The most widely used classification systems are API. Based on this, 2T engine oils are divided into 4 large groups:

TA. suitable for household appliances with an air cooling system and an engine volume of no more than 50 cm3.

TB. used for more powerful equipment with an air cooling system and a motor volume of 50.200 cm3.

TC. used in technology with high demands for oil quality. It is a high quality lubricant for 50.200 cc two-stroke engines. Great for lawn mowers, lawn mowers, trimmers, chain saws and other garden equipment.

TD. for outboard boat motors with liquid cooling.

Most suitable material for 2T motors of API-TB and API-TC class. However, it is necessary to refer directly to the product passport, where the manufacturer indicates the brand of engine oil recommended for its equipment.

Important! For lawn mowers, lawn mowers and other 2T gardening devices, a special engine oil is provided for two-stroke engines with an air cooling system and marked “for gardening equipment”. Do not use lubricant for 2T engines with liquid cooling system. Also not recommended oil for outboard engines, motorcycles and other equipment.

Oil to gasoline ratio for lawn mowers: why accuracy is so important?

All of us in childhood loved to “chew”, so the process of preparing a fuel mixture is not only simple, but also interesting. First of all, it is worth considering the fact that the proportions of the mixture may be different. This depends on engine configuration, oil markings and manufacturer recommendations. The fact is that with an insufficient amount of lubrication, the cylinder and piston heat up, which leads to shallow scuffing of all rubbing surfaces and, consequently, to the failure of the cylinder. piston group. Well, in the case of its excess, on the contrary, we get coking of the piston ring and the formation of a large amount of carbon deposits.

And even despite the fact that there is a generally accepted mixing ratio of 2% (for every liter of gasoline, 20 ml of lubricant). The proportions in the mixture are still recommended to be kept exactly.

How much to pour oil into gasoline for lawn mowers?

Everything is quite simple, subject to the correct balance, the engine runs at full capacity, all parts are thoroughly lubricated and do not wear out. As a result, we get a confidently working technique that will last more than one season.

To know how much oil to add to your lawn mower, you need to familiarize yourself with the performance of the product. Proportional ratios can be presented as follows: 1:25, 1:40 and 1:50, which means 1 part of oil for 25, 40 or 50 parts of gasoline.

1 liter of gasoline = 1000 ml

To determine the required amount of oil for a ratio of 1:25, you need 1000/25 and we will get a ratio of 40 ml.

We carry out the same actions for the ratio 1:40 and 1:50:

1:40 (for 1 liter of gasoline 25 ml of oil)
1:50 (for 1 liter of gasoline 20 ml of oil)

To ensure the correct proportion of lawn mower oil, it is recommended to use a special measuring container (not plastic). Eliminate the possibility of dirt and water getting into the fuel mixture. this may affect its quality. It is better to start preparing the mixture with gasoline. Pour it up to the required mark, then add oil. A couple of tilts of the container are enough for mixing. The liquid quickly combines and acquires a uniform hue, which, depending on the structure of the oil, can be red, green, blue or other. After that, a properly prepared mixture is poured into the equipment fuel tank.

Before using the equipment, make sure that the tank cap is tightly closed. If you have more fuel, then the remainder can be stored in a special canister or mixing container (no more than 14 days). It is recommended to drain the unused fuel.

Important! Be sure to follow the safety instructions. Mix fluids outdoors to prevent corrosive gasoline fumes from accumulating indoors. Wear gloves and long sleeves. Do not smoke or set anything on fire.

Petrol

RON 92 gasoline is considered the most popular type of fuel for two-stroke engines. Due to its relatively low cost, it is extremely rarely falsified. Therefore, not one hundred percent, but you can be sure of its quality. It is also permissible to use AI-95 fuel.

As for the storage of fuel, its period should not exceed 3 months. Over time, gasoline loses its properties, the resin becomes higher and a polymerization process occurs, which adversely affects the combustion chamber. The fuel mixture for lawn mowers prepared from low-quality materials settles in the form of carbon deposits, as a result of which the main components and systems of the engine suffer.

Recommendations for use and storage

The fuel is ready, poured into the fuel tank, the first spurt and the long-awaited start. However, if you want the equipment to work as long as possible, it is recommended to run it in for the first time. To avoid overheating of the engine, it is recommended to adhere to the average load. After the main elements of the system have been thoroughly lubricated, the load can be increased.

Certain rules should also be followed when preparing the braid for off-season storage:

Drain the remaining fuel from the fuel tank and carry out the final run until the fuel is completely depleted. Then, pause the work and make sure that the engine is completely cool.

How to mix your own fuel for STIHL chainsaws & equipment

Unscrew the spark plug carefully and add about 5 ml of lubricant. Pull the starter handle slowly to distribute the oil evenly inside the engine. Then, return the candle to its original state. Store equipment in a cool dry place.

How to dilute gasoline with trimmer oil instructions with a description

To cut grass in the country or in the field, you will need gasoline trimmers. They run on gasoline, unlike their electric counterparts. Far from many masters know how gasoline and oil for trimmers, petrol and lawn mowers are diluted. Step-by-step instructions for preparing the fuel mixture in the trimmer will be useful not only for beginners, but also for specialists who may be refueling chainsaws incorrectly.

We deal with the choice of gasoline for lawn mowers AI-92 or AI-95

How many people, so many opinions, which applies not only to the choice of oil for the trimmer, but also gasoline. Similarly, in order not to make a mistake with the choice, it is recommended to use gasoline of the brand recommended by the manufacturer (indicated in the manual for the tool). However, everything is not so simple here, since at each gas station, the brands of gasoline are only called the same, but they have a completely different composition. You need to figure it out and come to a common conclusion about which brand is better to pour gasoline into a two-stroke engine for your trimmer.

Manufacturers recommend using A-92 gasoline for their equipment, and some models require the use of A-95 grades, which do not contain ethyl alcohol. It is not recommended to use AI-90 and lower gasoline, as they will cause rapid wear of engine parts. When buying gasoline of one brand, you cannot be 100% sure that it corresponds to reality. The result is the following picture:

  • The manufacturer recommends pouring fuel into the AI-92 trimmer
  • The summer resident uses only gasoline of this brand, but buys it at gas stations, where the price is lower or where necessary
  • This negatively affects the internal parts of the engine, since at one gas station it is really high-quality AI-92 gasoline, and at the second. at best, if it is AI-80, not AI-76

As a result, the engine suffers, and after a couple of years of operation of the new trimmer, it becomes necessary to overhaul it. In order not to have to analyze the quality of fuel or buy only expensive gasoline, it is recommended to refuel at only one filling station. At filling stations, gasoline is poured only into metal cans, not plastic.

There are manufacturers producing special purified fuel for two-stroke engines. If this option is chosen, then you do not need to choose the best gas station, the brand of gasoline and control its shelf life.

Learning to dilute gasoline with trimmer oil if you overfill or overfill

If you bought a trimmer, lawn mower, lawn mower, chainsaw and other types of equipment, then you probably know that they use two-stroke motors as power units. These engines do not run on pure gasoline, like four-stroke engines, but on a mixture of gasoline and oil. In what proportion should gasoline be diluted with trimmer oil. every summer resident asks himself this question before preparing the tool for work. We will understand this issue in detail, since diluting gasoline with trimmer oil affects the service life of the tool, and improper preparation of the mixture will lead to rapid engine wear. What is the danger of excess or insufficient amount of oil in gasoline for a trimmer:

  • If gasoline is diluted with a large amount of oil (above the norm), then this will lead not only to the appearance of a large amount of smoke, but also to the formation of carbon deposits on the cylinder walls and a drop in power. This carbon deposit will cause piston wear, which will be diagnosed by a decrease in its performance.
  • If the gasoline does not contain enough trimmer oil, this is even more dangerous. After all, the working mechanisms of the engine will not be lubricated in sufficient quantities, which will eventually lead to their rapid wear (there is a rapid destruction of the piston rings and the engine jamming). With an insufficient amount of oil in gasoline, poured into the trimmer, engine wear will occur ten times faster

In order not to have to pay for mistakes with the cost of overhauling the engine or buying a new tool, it is necessary to fill the fuel of the correct consistency into the tank from the first day. You can find out the ratio in the instructions for the tool, since models from different manufacturers may give different recommendations. Usually this ratio is the following norms:

  • 1 in 25 or for 1 liter of gasoline 40 grams of two-stroke oil
  • 1 to 40 or 1 liter of gasoline 25-30 grams of lubricant
  • 1 to 50. this is 20 grams of oil per liter of gasoline

The standard value is considered to be 1 to 50 (indicated on canisters with oil for two-stroke engines), but it is necessary to rely on it in the most extreme case, since the manufacturers indicate the recommended proportion value, and if it is not observed, then the service life of the two-stroke motor is reduced.

In addition to keeping the proportion, you also need to learn how to prepare the mixture. After all, the option of adding oil to the gas tank is categorically contraindicated, although some do so. If you bought a trimmer or lawn mower, you will need consumables that you will use to prepare the mixture. Instructions for preparing the fuel mixture in the trimmer are as follows:

  • Prepare gasoline and two-stroke oil based on the above recommendations for the selection of lubricant and fuel
  • In addition, to prepare the mixture, you need to take a container or container. Usually a plastic bottle is used for this, to the selection of which an appropriate approach is needed. It must be clean inside. It is not recommended to use a container for milk, beer and other drinks. The best option is a container for mineral water.
  • It is very important that the container has an integer volume value, that is, 1 or 2 liters, so that you do not have to calculate how much oil to pour into a 1.5 liter, 1.3 or 1.25 liter bottle, because you can easily make a mistake.
  • You will also need a syringe, which is used as a measuring device for dispensing oil. For such purposes, a conventional medical syringe for 10 or more cubes is suitable. It is desirable that the syringe has an accurate measuring scale
  • After preparing the necessary materials, you can start cooking

Instructions for preparing a fuel mixture in a lawn mower:

  • First you need to fill the plastic container. The container is not full of 2 fingers to fit the oil
  • The required amount of two-stroke oil is drawn into a syringe, and poured into a bottle with collected gasoline. You need to do it this way, and not vice versa.
  • After adding a lubricant to the bottle, it requires you to close it tightly with a lid and stir. However, keep in mind that oils labeled “pre mix” need stirring. If the container with oil has the designation “self mix”, then you do not need to shake the container, and after combining the substances, you can pour them into the tool tank

After preparing the fuel mixture for the trimmer, it remains to fill the tool and start working. How to properly refuel trimmers, lawn mowers, chainsaws and other types of motor vehicles, we will consider in detail.

Choosing a lawn mower oil useful tips from professionals

If the instructions for the tool have been lost, and there are difficulties with choosing the right oil, then it is recommended to stop your choice on the following two options:

  • Semi-synthetic. they are cheaper than synthetics, but more expensive than mineral water. Suitable for equipment, both Russian and foreign. They have low smoke parameters, and adequately “take care” of the structural elements of the motor. Manufactured by ferrying petroleum products and hydrocarbons
  • Synthetic. expensive types of lubricants that are suitable for all types of equipment. If you use synthetics for your trimmer, then the engine of the tool will work like a clock.

When choosing and buying oils for dilution with gasoline, you may come across the fact that some letter designations are indicated on the cans. These designations are an API classification, which will be useful to find out who wants to fill the tool with a lubricant that is suitable for the parameters. Let’s consider all types of oils according to API classification for two-stroke engines:

  • TA. intended for air-cooled units with a volume of up to 50 cm3. These include mopeds, lawn mowers, trimmers and lawn mowers. Optimal solution for lawn mowers and trimmers
  • TB. used for refueling engines of units such as mopeds, chainsaws, scooters and motorcycles. The engine displacement of such equipment ranges from 50 to 200 cm3. This type of oil is also suitable for trimmers
  • TC. intended for dilution with gasoline and filling in motorcycles, snowmobiles and other types of land equipment
  • TD. serves for refueling outboard motors, hydro scooters and boats

API classification is an American standard that is used in Europe. However, when choosing, there are additional designations on oil cans for two-stroke engines, for example, FA, FB, FC, FD and others. This is the smoke emission classification of oils developed by the Japanese JASO standard. If such designations are found on the selected oils for trimmers and chainsaws, then their decoding must be taken into account:

  • FA. used in countries where the legislation provides for the minimum emission of smoke into the atmosphere. Emits an imperceptible fog of smoke during operation
  • FB. Designed for use in countries where there are strict restrictions on the emission of smoke into the atmosphere. Virtually no white smoke
  • FC. smoke emitted into the atmosphere is transparent and invisible to humans
  • FD are smokeless oils for 2-stroke internal combustion engines that do not emit smoke, but still have improved chemical properties. They are usually used for mixing with gasoline and refueling boats, boats and yachts.

If the container with the lubricant has the designation “self mix” and “pre mix”, then they mean. self-mixing with gasoline (the first option, which does not require shaking), and the need for forced dissolution (the second option).

Knowing the classification of oils by their types, it will not be difficult to choose the best option for your brand of lawn mowers. On the market you can find a variety of brands of oils for two-stroke engines, but it is better to pay special attention to such companies:

  • Stihl. produce mineral and synthetic, and semi-synthetic of this brand are rare
  • Shell Helix Ultra. Recommended by Specialists
  • Motul
  • Oleo-Mac
  • ECHO
  • Hammerflex
  • Lukoil is a Russian oil that costs 3 times cheaper than foreign analogues, but at the same time has excellent quality indicators

Product are not indicated as vary. There are many other brands, and if you still want to find the perfect trimmer lubricant for yourself, then it is recommended to watch the test in the video clip below.

From the video, we can conclude that it is not always useful to buy expensive oils, since they may turn out to be of unsatisfactory quality, which can be seen in a real example.

How to choose trimmer oil or types of lubricants

Trimmers and lawn mowers are powered by two-stroke engines, which have a simplified design. Rarely, there are trimmer models with 4-stroke engines that run on pure gasoline. Two-stroke power units do not have a compartment for filling engine oil (oil sump), thereby reducing the weight of the tool and reducing their cost. If the rotating parts of the motor are not lubricated, they will eventually fail quickly. To prevent this, the trimmer is not filled with pure gasoline, but with a mixture of oil. What oil to dilute with gasoline for a trimmer?

To begin with, let’s remember or find out what types of oils are produced by chemical composition:

  • Mineral liquids. designed for low-power equipment with air cooling. It is the cheapest type of engine lubricant.
  • Semi-synthetic substances. they are used for equipment that has air and water cooling
  • Synthetic. suitable for all types of motors with different types of cooling. They do not require frequent replacement, and this type of lubricant is several times more expensive than mineral and semi-synthetic

From the above it follows that oil with any composition is suitable for a trimmer. mineral water, synthetics and semi-synthetics. Oils with different chemical compositions differ in price, therefore, when buying, it is necessary to rely on the recommendations of the tool manufacturer. The instructions indicate advisory information on which types of oils are best to use. If this is the TC-W3 standard, then it is not so important what composition the substance should have. In this case, mineral water, semi-synthetics and synthetics can be diluted with gasoline.

How to properly fill the finished fuel into a two-stroke engine

Many do not follow some important recommendations for pouring fuel into the gas tank of the trimmer or lawn mowers, which ultimately leads to unpleasant consequences. Let’s consider important recommendations on how to properly fill the gas tank of lawn mowers with diluted fuel from gasoline and oil:

  • Prepare a funnel or watering can. Despite the large diameter of the hole in the gas tank, very often when trying to get into it, some part of the fuel is spilled, which gets on the body of the tool. Fuel trapped on the tool can cause a fire when heated, so it is very important to use a funnel or watering can.
  • Before unscrewing the plug, thoroughly clean the surface of the tank, as dirt can get inside, which will cause a quick clogging of the gas filter
  • Fuel filling operations must be carried out in calm weather or in a secluded place to exclude the possibility of dust and small grains of sand getting inside the tank.
  • Do not leave the tank hatch open for a long time, as not only small grains of sand and dust, but also insects can get into it
  • Do not inhale gasoline vapors while filling, as they are dangerous to humans. When working with a trimmer, the master must use safety glasses, earmuffs and a respirator
  • It is necessary to pour fuel into the tank up to the mark. If you fill the tank full, then when screwing the plug, some of it will pour out. wasteful use of fuel. In this case, it is better to underfill than overflow.

Given these recommendations, you can significantly extend the life of the gasoline tool in question.

Trimmer Ready Mixed Storage Tips

After refueling the trimmer, many put aside the mixture in the bottle until the next time. Sometimes this next time does not come soon, and stretches out until the next year. It is impossible to store the finished mixture for so long, as the oil decomposes. After preparing the mixture, it must be consumed within 1-2 weeks. In addition, it is also impossible to store the tool for a long time with the fuel mixture poured into the tank, since the effect will be the same. To prevent unforeseen circumstances, it is recommended to consider the following recommendations for storing a ready-made gasoline-oil mixture:

  • Prepare the fuel mixture in the amount that will be used. If you don’t know how much fuel you use, then it is better to cook less
  • If a fuel mixture remains in the trimmer tank (when the tool is hidden until the next season), then it must be completely used up or drained
  • Before adding the prepared mixture to the tank, stir it thoroughly
  • Store the prepared mixture in a tightly curled container, as well as in a place limited to exposure to sunlight

Subject to all recommendations, the service life of the trimmer will be no less than indicated in the instructions. The use of high-quality consumables in pairs, observing the recommendations for preparing the mixture in the trimmer, will entail a long and effective service of the gasoline tool.

Oil brands that are best suited and their classification

To dilute gasoline in two-stroke engines, synthetic or semi-synthetic oils are used. There are also mineral oils, but their use is not recommended by manufacturers due to solidification at low temperatures. It is advisable to buy adapted engine oils, on which it is written that they are intended for preparing a mixture in two-stroke engines. A common brand is API-TB and less commonly API-TC. Usually on the packaging of the oil, the ratio in which it should be diluted is indicated.

Do not use cheap counterparts, as the life of your tool depends on this.

Buy well-known brands that maintain the quality of their oils over the years. For example, the Husqvarna brand only offers the highest quality diluent oils in proportions that are significantly lower than other brands.

Why dilute gasoline with oil?

The use of a two-stroke engine on a chainsaw is due to the fact that it is more economical in fuel consumption, while it has more power per unit volume. Four-stroke motors are used on various garden equipment such as tillers, mowers, trimmers, etc. If you focus on efficiency, then four-stroke win significantly. The principle of operation of two-stroke engines is that the oil is not poured into the tank separately, but is diluted with gasoline. The presence of oil is required, since without it the engine will quickly become unusable.

What is the risk of pouring pure gasoline without oil?

Two-stroke engines are designed in such a way that they cannot run on pure gasoline alone. The addition of oil is necessary in order to lubricate the surface of the spark plug electrodes and nozzles as a result of work. If this is not done, then rust will corrode the contacts.

Modern chainsaws with two-stroke engines use AI gasoline and an octane rating of at least 90, for example AI-92 or AI-95. But it should be noted that the AI-95 brand is less popular among owners of chainsaws, since it is more expensive and contains more methyl tert-butyl ether, which helps to reduce the risk of fuel detonation.

Experts strongly discourage the use of “old” gasoline, which has been in the can for a long time. Since condensation could form on its walls, which subsequently gets into gasoline and degrades its quality. You need to take only fresh gasoline that does not contain sediment. Alternative fuels cannot be used.

How to properly prepare a fuel mixture for a chainsaw

Chainsaws are equipped with special engines that run on a fuel mixture consisting of gasoline and oil. The constituent ingredients are calculated in certain proportions so that the efficiency from the use of the tool is even greater. The durability of the tool also depends on the quality of the poured.

The nuances of preparing a mixture for a chainsaw

In order not to make a mistake with the preparation of the fuel mixture, read carefully the instructions for the saw. There, the manufacturer always indicates the dosage required for a specific model with a certain dosage capacity. Pay special attention to Chinese models, as their manufacturers prefer a 1:25 ratio.

Recommended proportions of global brands:

STIHL 1.5 kW. (1:50);

Husqvarna 1.5 kW. (1:50);

Below is a table showing the proportions for preparing the fuel mixture.

You can store the ready-made mixture for no longer than 2 months. With longer storage, the octane number of gasoline decreases, and this can cause the engine to stop working.

  • Perform preliminary mixing in a special dry container;
  • Do not mix the mixture in the saw tank;
  • Use only the required dosage;
  • Gasoline is poured first, then oil. Not in reverse order, otherwise the oil will stick to the bottom and not mix;
  • Do not store the mixture for a long time;
  • Do not mix more than necessary for the job.

How to calculate the fuel consumption of a chainsaw?

The rate of fuel consumption per hour depends on the brand and model. Below is a table of the consumption of liters of fuel mixture per hour:

Helpful information

Correctly mixed mixture will ensure uninterrupted operation of the engine, complete combustion of fuel without the formation of carbon deposits, smoke or scuffing.

For the mixture, you must use 92 gasoline and two-stroke engine oil (synthetic).

Fuel below 92, with a lower octane number will not work. The 95th is not recommended, because it contains many different additives that can negatively affect the operation of gasoline equipment.

Knead the mixture before each application of the technique. Don’t mix too much.

The oil-fuel mixture cannot be stored for more than 2 weeks, then irreversible oxidation processes occur, and changes in the composition of the mixture.

properly, prepare, trimmer

The proportion is as follows:

1:50

that is, for 1 liter of gasoline. 20 milliliters of oil.

(or this is the proportion of 100 ml of oil per 5 liters of gasoline).

QUICK TIP #4 : How To Mix 2 stroke (Two cycle) Gas

A full tank at full load lasts from 30 to 45 minutes, if you do not plan to use the equipment for so long, do not fill a full tank.

Do not use old gasoline, it wears out over time and the octane number changes.

Never refuel a gasoline-powered tool with a 2-stroke engine with clean gasoline, as this can lead to serious and costly repairs.

You can only refuel with a gasoline-oil mixture.

Why the wrong proportion can disable the technique?

The thing is that, unlike 4-stroke, 2-stroke engines do not have an external lubrication system for the internal parts of the engine, a properly prepared fuel mixture is very important for them.
If you add a little oil, then the lubricating properties of the mixture will decrease, this will lead to quick wear of the equipment.
Conversely, if you add too much oil. this will violate the combustible properties of the mixture and greatly reduce the power of the equipment.

The two-stroke engine does not have a separate oil sump, and all rubbing parts inside the engine are lubricated with oil. which is contained in the fuel mixture.

The oil should lubricate all rubbing surfaces inside the engine and burn without the formation of carbon deposits. This is the fundamental difference between oils for 2-stroke engines and 4-stroke.

In addition to the above functions, the oil should:

  • to seal the gaps, primarily between the parts of the cylinder-root group, to prevent and minimize the breakthrough of gases from the combustion chamber.
  • remove heat generated by fuel combustion and friction.
  • prevent corrosion of engine parts.

How to knead?

Mix ingredients in petrol resistant containers, not in the tank itself!
Pour gasoline into a clean and dry canister, then add oil there.

It is not necessary in the reverse order. the oil poured first will stick to the bottom and can hardly be mixed later, you will have to put in more effort.
After adding both ingredients, close the container tightly, and shake thoroughly, actively mixing the components.

Fuel mixture: the proportion of oil and gasoline for the chainsaw

The chainsaw engine is the heart of the tool, so it is very important to use a properly prepared fuel mixture.

The fuel mixture for a chainsaw is prepared from two components. oil and gasoline. Chainsaws are equipped with two-stroke engines, so oil is not added to the lubrication system (like in a four-stroke engine), but directly to gasoline. At the same time, it is very important to observe the correct proportions of ingredients, of course, in no case try to work on pure gasoline, because in this way you will very quickly “kill” the chainsaw.

If we talk about what kind of gasoline to pour into the chainsaw, then it will be optimal to use fuel with an octane rating of A-95, in this case the savings on fuel can turn out to be deplorable. Often European manufacturers indicate that it is possible to use A-90 or A-92 gasoline, but in post-Soviet countries the quality of gasoline is inferior to that of Europe, so in our realities it is better to use better quality gasoline.

As for the proportion of the petrol-oil mixture itself, everything is simple here: you must follow the instructions for the tool. All manufacturers of chainsaws indicate the required ratio in the operating manual or in the passport of the tool, in addition, the proportions for refueling the chainsaw may differ depending on the model of the chain saw. As a rule, the proportion of oil and gasoline to a chainsaw of famous manufacturers is a ratio of 1:40 or 1:50, which means 1 part of oil for, for example, 40 parts of gasoline. Now arithmetic 1 liter of gasoline = 1000 ml of gasoline, divide by 40 and we get 25 ml of oil. If you follow the same steps to a 1:50 ratio, you get 20 ml of oil per 1 liter of gasoline. As for budget chainsaws made in China, the situation is slightly different. The ratio of gasoline to chainsaw oil made in China 1:25, that is, divide 1000 ml of gasoline by 25, we get 40 ml of oil. The thing is that in branded chainsaws, a solid assembly and the distance between pistons and cylinders in the engine is much less than that of Chinese chainsaws, therefore, the required amount of oil differs almost twice.

In order to measure the correct amount of oil, use a conventional medical syringe of sufficient volume.

Another subtlety. first fill the dry gasoline can with gasoline and then oil. The procedure, on the contrary, is fraught with a low quality fuel mixture, because the oil is more dense, it will stick to the bottom of the canister. what a good mixing here.

Be sure to prepare the fuel mixture in a canister and pour ready-made special fuel into the gas tank! Never cook or mix directly in the fuel tank of your chainsaw!

If you figured out the question of how to breed gasoline for a chainsaw, then on storage conditions and shelf life of the fuel mixture it is worth saying a few words. It is best and easiest to prepare a petrol-oil mixture for 1 liter of gasoline, it is recommended to do this immediately before working with the tool. Chainsaw fuel tanks have a volume of 0.3 to 1 liter. In the conditions of domestic use, the entire volume of the prepared combustible mixture is rarely used in one session, so the remainder can be saved until the next session. It is necessary to store the fuel mixture in a special canister for gasoline, in a dry, dark place. It is optimal to count that the shelf life of the finished mixture will be 7-10 days. The fact is that the oil on the market now is not synthetic, but organic, that is, natural. After 10 days, all lubricating properties are lost, gasoline simply “eats up” the oil. Naturally, it is no longer possible to use such fuel, this can cause breakdown and failure of the chainsaw.

At the end of the work, it is necessary to drain the fuel mixture, start the chainsaw, the tool will stall (so that the saw has a dry carburetor) and now you can leave it until the next operation session.

Unsuitable fuel mixture must be disposed of.

The principle of operation of a two-stroke engine

Each manufacturer of gasoline and fuel oils gives recommendations on the use of products. In order for the chainsaw to work at full power, it is necessary to determine the required proportions: 1:50 (oil to gasoline). how much it is, it is important to choose the correct ratio.

On the back of the package, as a rule, instructions for the use of fuel are attached.

The easiest way to find out how to mix 1:50 (oil to gasoline) is to use the data in the table:

Proportion view The amount of gasoline, l Oil amount, ml
1:50one20
1:501.5thirty
1:50240
1:50360
1:50four80

Before filling the equipment, you need to correctly calculate the amount of each product.

When preparing the fuel fluid, the total volume in liters is calculated

Gasoline and trimmer oil proportions

Regardless of what type of equipment you plan to use, you need to choose the right proportions and prepare the fuel mixture. The most common question: how to dilute gasoline with chainsaw oil and not be mistaken.

A suitable product must be purchased before filling the fuel tank. Unleaded fuel is best for gardening equipment. It is ideal for such mechanisms. Before buying fuel, you must study the factory instructions for the equipment.

It is recommended to fill the lawn mower or other equipment with a product with an AI-90 or 92. After it became clear how many liters of gasoline you need oil, the chainsaw is refueled and used as intended. It is best to purchase proprietary formulations of the API TB class. They are suitable for use at positive air temperatures.

When trying to figure out how much oil to add to your chainsaw gasoline, you should look at the average proportions. Most often, dilution is carried out at an indicator of 1 to 50.

Also, it is important to determine the total volume, then it will become clear how much oil to pour into gasoline for a chainsaw. For a single job using special garden equipment, filling per liter is sufficient. If the tool is used regularly, then the average volume is 3-4 liters.

Powerful chainsaw consumes a lot of fuel

How to prepare a fuel mixture. the rules and features of the process

Before you mix the oil-gasoline solution, you need to find out the exact proportions. The operation of any device, including a chainsaw, must be carried out exactly according to the instructions attached by the manufacturer. The technical document states how much oil to add per liter of gasoline.

To mix gasoline with trimmer oil, you need to study the characteristics of the device. If the distance between the pistons and cylinders is large, it is more difficult to maintain the normal operation of the mechanisms. Primary formulations are poured into a container for mixing gasoline and oil using a large medical syringe or any other convenient method.

To dilute gasoline 1 to 50, you need to know for sure how much will have to be filled.

It is not recommended to mix oil and gasoline in the fuel tank

A mixture of gasoline and oil for two-stroke engines

When buying equipment, you should study the instructions. in it, the manufacturer can recommend the best way to prepare the fuel mixture. For air cooled models a 1:40 mix is ​​used. Equipment that uses synthetic oil is best suited for fuel diluted 1:50. It is necessary to select the desired option in each case for a specific device.

Work is carried out in high-quality and dense gloves

After the ratio of oil and gasoline for the trimmer is determined, you can refuel the device.

It is better to pour liquids into the tank in the fresh air, and not in the garage.

Recommendations for preparing the mixture and filling the gas tank:

To find out how to dilute gasoline with trimmer oil, you need to study the instructions for the device.

Always check the expiration dates of gasoline and oil

Oil to gasoline ratio

Depending on the model of equipment and the type of engine, filling with gasoline and oil is carried out in different proportions. It is important to make the right choice so that the working mechanisms serve as long as possible.

Before mixing gasoline with trimmer or chainsaw oil, you must determine the required amount of one and the other fluid. The ratio of gasoline to chainsaw oil can be different: 1:50, 1:40 or 1:25.

Manufacturers offer a huge amount of funds

The amount of gasoline must be determined in liters, and the oil is calculated in ml.

The proportion of oil and gasoline for two-stroke engines: instructions for “dummies

The correct proportion of oil and gasoline for two-stroke engines will help to achieve better equipment performance. Dilute the two types of liquids in different ratios. The Homius editors offer simple instructions for the dilution of technical fluids for those who have just purchased a device with a two-stroke engine.

Proportion of oil and gasoline for outboard motor

Two-stroke boat motors must be filled with a homemade solution of two types of fuel. To find out how much oil to add to gasoline for a trimmer or engine, you need to consider the stages of equipment operation:

  • initial run-in. dilution 1:25 is required;
  • long work. 1:50;
  • short period of work. 1:40.
properly, prepare, trimmer

After the original packaging is opened, the properties are retained for six months, however, the manually prepared mixture is stored for no more than a month.

The manufacturer should always indicate in the instructions for the motorboat which solutions are suitable for a particular model. To find out how much oil to pour into gasoline for a trimmer or outboard motor, you need to familiarize yourself with the factory documents.

It is recommended to have a supply of mixture in a canister while sailing in order to refuel the engine if necessary.
