Trimmer Oil 2 Stroke Proportions

What gasoline to fill

Gasoline for the trimmer should be chosen unleaded with a stroke number of 92 or 95. As practice shows, AI-80 gasoline can lead to device breakdowns, which is a questionable economy.

Fuel must be fresh, that is, after purchase it can be stored for no more than 60 days.

Other factors also affect the quality of the fuel, such as using a special lawn mower lubricant and diluting it in a separate container. It is also recommended to use special canisters designed for storing gasoline.

The choice of oil and gasoline for preparing a fuel mixture for a trimmer: dilution ratio table

A trimmer, or lawn mower, is an indispensable tool in the household. over, its reliability, efficiency and long service life depend on many factors. For example, the quality of fuel. This means that you need to select the correct oil for the trimmer, observe the proportions when adding to gasoline and the rules for refueling the device.

How to dilute gasoline with trimmer oil

Dilute trimmer gasoline in the correct proportion. An insufficient amount of oil can lead to poor lubrication of the mower components, which contributes to rapid wear. In the event that the oil is more position, carbon deposits will form on the pistons and spark plugs. Carbon deposits on the moving parts of the engine interfere with normal operation and lead to early engine damage.

What proportion is required for a particular trimmer model can be found in the attached instructions. Most often, for 2-stroke gasoline engines of lawn mowers, a fuel mixture is used in a ratio of 50: 1, where 50 is part of gasoline, 1 is part of oil. That is, 20 ml of oil should be added to 1 liter of gasoline. The table will help you choose the required ratio.

To correctly measure the proportions, use measuring containers with a milliliter scale. For THESE purposes, a special double-necked canister is perfect, it is designed for mixing and storing oil gasoline. For example, oil can be drawn with a medical syringe without a needle. Before mixing liquids Make sure that the ready-mix container contains water, dust and dirt particles.

It is unacceptable to dilute gasoline with lubricant directly in the fuel tank; moreover, the proportion of oil and gasoline must be strictly observed. If you ignore this rule, then the trimmer motor may be unstable, due to which it will quickly fail.

It is not recommended to use plastic bottles or canisters for this purpose. This is due to the fact that gasoline tends to dissolve plastic, which means that some of the plastic can get into the fuel tank, which can lead to carburetor breakdown. Although there are special plastic canisters with markings “flame”.

This will require:

Petrol;
Oil suitable for air-cooled two-stroke engines;
Canister, preferably metal;
Mixing vessel, also better metal;
Gloves;
Respirator.

In addition to protective equipment, do not forget about fire safety rules, because gasoline and engine oil are highly flammable:

It works better outdoors to avoid the accumulation of gasoline vapors indoors;
Do not smoke and create spark situations.

Make a mixture of gasoline and oil as follows:

Pour 1 liter of gasoline into a container, add half the required portion of oil. Mix thoroughly, do it with extreme caution away from sources of open fire.
Add the rest of the oil to the trimmer gasoline and mix thoroughly again. Fuel can now be poured into the trimmer fuel tank.

The mixture can be stored for no more than three months, so it is better to dilute gasoline in such an amount that it is enough for a few used.

Which oil to choose

For effective trimmer operation, it is necessary to select oil for two-stroke engines. This is due to the lack of an oil sump in such a device. Depending on the chemical composition of the oil, the following classification is distinguished:

Mineral. based on petroleum distillate, suitable for low-power and air-cooled equipment, but requires frequent replacement and can only be used in good weather in the warm season;
Semi-synthetic. suitable for garden equipment with air and liquid cooling;
Synthetic. based on esters, and do not require frequent replacement and can be used at any time of the year.

Oil for 2-stroke engines is characterized by good solubility and complete combustion feature. It is recommended to use a lubricant for the trimmer that is suitable for air-cooled units. Most often, it is indicated on the packaging that the oil is intended for garden equipment and is marked I, TV or TC. over, the last of them is the most preferable.

If the consumption of engine oil during the summer season is planned to be large due to the presence of a chainsaw, brush cutter, lawn mower in the garden arsenal, then it is advisable to buy 5 liters of oil at a more favorable price. If it is needed only in order to mix with gasoline and fill the only tool, then 1 liter will be enough.

Lawn mowers often produce the right oil, so you can make your choice easier if you choose the right brand fluid.

How and how much to refuel

Filling the trimmer fuel tank is easy. To do this, place the tank in such a way that the lid is on top. The amount of fuel depends on the trimmer model. This information is indicated in the instructions, there is also a mark directly on the tank.

Doing so can cause fuel to spill into the intake manifold and fuel filter, which can cause engine damage or fuel ignition.

When refueling the trimmer, you must observe safety measures:

Try to fill in the liquid so that it does not spill, you can use a watering can for this;
If gasoline still spills, then wipe it up immediately;
The trimmer should be started after the container with fuel is removed to a safe and secure place, preferably at a distance of more than 10 meters;
If there is a long break between operation, drain the remaining fuel.

Correct proportion and adherence to mixing and filling techniques will help prolong the life of the trimmer. In this case, it is recommended to choose only a high-quality product of the corresponding brand.

Fuel mixture preparation rules

The process of preparing the fuel mixture should begin with a detailed acquaintance with the instructions attached to it. As mentioned at the beginning of the article, some drivers who, in their opinion, have incredible experience, do everything “by eye”. Of course, over time, each driver knows how and what to do, however, each mixture has its own differences, so it will never be superfluous to get acquainted with the advice from the manufacturer.

The main rules for operating the fuel mixture include:

Do NOT under any circumstances reduce the proportion of oil to gasoline. Oil is an expensive component, so many people decide to save on it. However, an insufficient amount of oil in the mixture leads to strong heating of the piston and cylinder of the engine. Because of this, seizures appear, which ultimately leads to the need for serious repairs.
DO NOT use too much oil in relation to gasoline. Increasing the proportions of the oil is also detrimental to engine performance. An excessive amount of oil leads to an increase in carbon deposits and rapid wear of the engine mechanism. Repair in this case will cost as much as in the first case.
Do not store the prepared mixture for more than 30 days. Otherwise, it loses its properties and the use of such a mixture can harm the engine.
Do not allow dirt, dust and second mechanical debris to enter, due to which the engine may become unusable.

Proportions and mixing process

How to determine the proportions for mixing oil with gasoline? Standard proportions To be indicated on the oil container. The amount of oil used may differ depending on the manufacturer, but proportions of 1:40 or 1:50 are often used. A slight deviation from this ratio is allowed. This will not entail serious consequences.

Having determined the exact proportions, you need to proceed to the direct preparation of the mixture. How can this be done? Various containers are suitable for this. Important: in no case should you mix fuel and oil directly into the gas tank, pour one liquid after another in turn. the mixture is always prepared separately and only then is slowly poured into the gas tank.

A wide variety of mixing tools can be used, including:

Special mixing containers. These are handy canisters with two separate compartments. separate for gasoline and oil. To prepare a mixture in such a container, you just need to pour the required amount of liquid, close the container and tilt the canister several times. Such devices are very convenient, but they are also quite expensive. If you have to mix the mixture often enough, then you should think about purchasing such a container.
Conventional metal and plastic canisters. Standard canisters. The most practical of these. One has only to be careful when using plastic and glass canisters, because when using them, there is a possibility of an electrical discharge. If you need to prepare a small amount of the mixture, you can use a regular plastic bottle.
Handy means. To save money, many people use improvised devices, for example, children’s horns and even syringes. Such funds are not very convenient, but they cost a penny.

How to mix 2-stroke gasoline and oil

The ratio of oil to gasoline is the main fuel for two-stroke engines. The fuel mixture guarantees efficient operation of the engine, helps to preserve its moving parts and reduce the number of breakdowns.

Signs of misuse

Using a dirty or disproportionate mixture can lead to serious engine malfunctions. If you made a mistake when mixing. it’s okay, because the car itself will tell you about it. You just need to be attentive to some signs, among which:

The appearance of dirt and various deposits on the carburetor.
Rapid clogging of the fuel filter located in the gas tank.
Oxidation of the carburetor walls and loss of elasticity of the rubber diaphragm in various parts of the gas tank. This symptom manifests itself only with prolonged storage of an unsuitable mixture directly into the gas tank of a car.

How and what to store the finished mixture?

Manufacturers recommend storing the fuel mixture in a clean container, preferably in a metal container. In no case should the mixture be left in direct sunlight, because this will lead not only to the loss of its properties, but also to other very unpleasant consequences. The maximum shelf life of the finished mixture is 30 days.

Depending on how often the car is used, some drivers prepare the mixture once a week, others once a month. Of course, NOT every owner has the time to constantly measure the proportions and mix fuel with oil. It is important to remember that the fresher the mixture, the better it is for the engine.

Many people use plastic cans and bottles as containers for storing the mixture. It is convenient and practical. There is always room for a small plastic bottle. However, you should be careful in this. The fact is that during long-term storage in a plastic container, the fuel mixture can literally “eat through” a hole in it. The process of corroding plastic is very fast. Therefore, it is best to use metal containers.

Perhaps it is not so convenient, but it is more reliable. If, nevertheless, there is a need to use a plastic canister, then remember that you can store the mixture in it for no more than two to three days. Then it needs to be poured into another container.

Fuel and oil for mixing

It is not always easy to properly prepare the fuel mixture. It is necessary to correctly calculate the proportions, mix the liquids and store the finished mixture correctly. Some drivers use their own recipes, add their own “secret” ingredients, which may even include soda. To prepare the fuel mixture was not a problem, you need to follow a few simple rules and follow the instructions from the manufacturer.

To prepare the mixture, use standard gasoline and oil from various manufacturers. What brand of gasoline should I use to prepare the oil mixture? Some people mistakenly believe that 80-grade gasoline is best suited, because it contains many different additives. This is partly true, but it does nothing better than gasoline 92nd and 95th brands.

over, it is very difficult to get gasoline of the 80th grade, because not one large fuel producer in the country now produces Ego. Therefore, the best option is gasoline of the 95th brand, which has almost the same cost as gasoline of the 92nd brand.

What is the best oil for mixing? It all depends on the driver’s preferences in a particular manufacturer. The only thing is important to use oil only for its intended purpose. If oil for tractors or boats is for a car it is not worth using.

Formation of gummy deposits in the carburetor area.

At the slightest manifestation of one of the signs, it is necessary to make changes in the mixing process, choosing more suitable proportions. This way you can select the ideal fuel mixture and avoid serious engine malfunctions.

In order to independently prepare the correct fuel mixture, which will ensure ideal engine performance, you must use the correct fuel, strictly adhere to the proportions indicated by the manufacturer, use a suitable container and store the ready mixture for NOT longer than 30 days. By adhering to THESE rules, you will prepare the perfect mixture for your car engine.

Tips for choosing

Now let’s try to understand how to choose a quality trimmer oil that runs on gasoline. The main feature to look out for is the base number. This moment excludes oxidation of the parts in which friction is observed, and slows down their deformation as much as possible. The more this compound is used, the faster it loses its alkalinity and becomes more oxidized. The optimal indicator of acidity (PH) is a value of at least 8-9 units.

The second important factor, which also has a serious impact on the performance of the gasoline trimmer, is the viscosity of the oil. This characteristic determines the ability to use the device at different temperatures. Summer brands of oils begin to thicken already with a minimum temperature drop.

The third point, the importance of which should not be underestimated, is the flash point. This indicator should NOT be less than 225 degrees. Otherwise, the composition will burn out very quickly and the load on the piston group will begin to increase, which will cause its accelerated wear. Also, 4-stroke oil will not work for 2-stroke. Namely, the latter type of motors is used in the vast majority of lawn mowers.

If we talk about manufacturers, then you can make a small rating, which will allow you to navigate the formulations offered by various manufacturers. For example, Stihl offers quality synthetic and mineral oils, which have already proven themselves as an excellent solution at any time of the year.

Shell Helix Ultra oil is considered very good. Experts note its high characteristics and excellent indicators of alkalinity and viscosity. In addition, the products of such brands as Oleo-Mac, Motul, Hammerflex, Echo are considered worthy. If we talk about the products of domestic brands, then you should pay attention to Lukoil oil. Its price is several times lower than foreign counterparts, but at the same time it has high quality and good technical characteristics.

Petrol trimmer oil: types and recommendations for use

Gasoline trimmers are among the most popular mowing tools. They are easy to use, mobile, allow the person NOT to depend on an outlet and show excellent results in the places where they are used. But for the stable operation of a gasoline trimmer, high-quality consumables are needed. In particular, we are talking about gasoline and oil. It is in the last component that we will talk in this article.

Varieties

The oil that is poured into the engine may differ in the production method. According to this criterion, it happens:

Mineral. this type is obtained during the processing of petroleum products;
Synthetic. it is obtained by processing or synthesizing gas;
Semi-synthetic. this type has more advanced characteristics due to the introduction of synthetic-based components into it.

Lawnmower oil refers to formulations intended for use in air-cooled engines that have a combustion chamber volume of 50-200 cubic centimeters. In addition, any two-stroke oil may differ from analogs in additives, which give it certain additional characteristics. They are of the following types.

Antiwear. The main task of the oil will be to reduce wear of parts during the operation of the device.
Antioxidant. They DO NOT allow oxidation to occur and make it possible to maintain the performance of the oil for a long time.
Anti-corrosion. Their job is to prevent corrosion from forming on engine parts.
Friction modifiers. These additives can significantly reduce the coefficient of friction.

Recently, when purchasing oil for dilution with gasoline, users are very often faced with the fact that special letter abbreviations are applied to the canister. These designations are made within the framework of the API classification. Consider what types of oils exist in accordance with it.

And it is used for air-cooled lawn mowers, the engine capacity of which is no more than 50 cubic centimeters. It can be used Not only for mowers, but also for mopeds, lawn mowers and other types of equipment. For a petrol trimmer, this is the optimal solution.

TB is used to refuel a chainsaw, scooter, moped or motorcycle, the engine of which does NOT exceed 200 cubic centimeters. Can also be used for refueling petrol trimmers.

TC is suitable for thinning with gasoline and pouring into a snowmobile, motorcycle and other types of equipment.

TD is intended for refueling boats, yachts and gyro scooters.

But in addition to this classification, other letter designations of the FA-FD type are often found. It should be said that the API is an American standard that is used in Europe. But there is a discrepancy between European and American smoke emission regulations. For this reason, additional letter designations should be taken into account.

FA can be used in countries where minimum exhaust gas emissions are required by law. Faint smoke may be emitted when using oils with this mark.
FB. can be used in countries where the restrictions on the emission of smoke and gases are much stricter. In this case, the smoke will practically not be emitted.
FC. smoke of a transparent color appears here, as the human eye cannot notice.
FD is a special category of oils for 2-stroke engines, they do not create smoke at all. They have enhanced chemical characteristics. Usually this oil is used for mixing with gasoline and subsequent refueling of boats and yachts.

In addition, oils come in two more categories:

Selfmix;
Premix.

In the first case, this will mean that it is necessary to carry out self-mixing, which does not require shaking, and in the second case, you will need to do it too.

Requirements

High-quality oil that can be poured into a gasoline trimmer must meet a number of requirements and standards in order to ensure reliable operation of the device and its performance. The oil should:

Provide increased wear resistance for various elements (in particular, the gearbox is especially susceptible to this)
Provide the lowest possible smoke and exhaust emissions;
DO NOT allow premature ignition;
Mix well with gasoline when exposed to low temperatures;
Have good viscosity and flow characteristics in various temperature ranges;
Be as safe as possible in terms of environmental impact.

As mentioned, two-stroke engine oil will differ from four-stroke engine oil. It has higher power, which is why fuel for it is obtained by mixing a certain amount of gasoline and oil. The ratio will be different for each lawn mower. You can find out its meaning in the instructions for the device. These proportions must be observed with maximum accuracy. When adding additives, take into account the type of motor.

If mineral oils are used, the mixing should be somewhere in the ratio of 1: 25, 30 or 35, depending on the type. If we are talking about synthetic analogs, then the proportion will be 1: 50 or 80 That is, a certain amount of oil is dissolved in the volume of gasoline.

Appointment

Engine oil is a special blend of solvent and friction-reducing additives. They form a certain viscosity and DO NOT allow the composition to thicken when the temperature is lowered. Usually oils are specially colored in different colors: green, red or blue. This allows them not to be confused.

Please note that they may vary in composition, so petrol trimmer oil will be labeled “for gardening”. In addition, it may still differ in marking: “2T” or “4T”. The first is two-stroke oil that is filled into the corresponding engine. And the second is intended for pouring into the crankcase.

How to use?

For the proportion of oil used, see above. Let’s say right away that you should not deviate from the indicated values and dilute gasoline by eye. At best, you just need to change the oil, and at worst, engine damage cannot be avoided.

It is important to be able to prepare the mixture correctly. It cannot be poured into the gas tank. It is better to pour the oil into a special container that already contains gasoline. A plastic bottle of mineral water is perfect for this. It is very important here that it is clean, which is why beer or milk bottles will not work. And it is better that it be a liter or two-liter, since it will be difficult for many to calculate how much oil to fill in a 1.5-liter or 1.25-liter bottle. You will also need to have a syringe on hand that will function as a dosimeter. It is best to take a regular medical one for 10 or more cubes.

Now explain step by step how to make a good gasoline trimmer oil.

First, you should find out exactly what type of oil is required for a particular braid model, as well as find out the exact ratio of gasoline and oil to create a mixture.
Then you need to fill the container. The container should not be filled with gasoline to the end, because oil must still fit there;
Now we draw the required amount of 2-stroke oil into the syringe and pour it into a bottle of gasoline. You cannot do the opposite, otherwise all ingredients will need to be replaced, and the mixture will need to be done again.
Close the bottle with a lid and stir. Here it is important NOT to forget that you need to stir the mixture if the words Premix are on the bottle with oil. If it says Selfmix, then after mixing the substances, everything is poured into the tank.

Now all that remains is to refuel the petrol trimmer, and you can carry out the necessary work.

For information on how to choose oil for gasoline trimmers, see the following.

Choosing a lawn mower oil

For trimmer engines it is necessary to choose oils marked “2T”, which are used for internal combustion engines with a volume of 50 to 200 cm 3 and are air-cooled. First of all, when buying oil, you should pay attention not to the price, but to the protective properties of the material, since small savings can subsequently become a real headache for the owner and, as a rule, high costs.

Two-stroke lawn mower oil

The main factor in determining the quality of trimmer oil is the base number. It is this component that excludes oxidation of rubbing parts and slows down their destruction. During operation, the oil gradually loses its alkalinity and becomes oxidized. The optimal acidity level (Ph) should not be less than 8-9 units.

The viscosity of lawn mower oil also has a big impact on how gasoline tools work. This indicator determines the ability to operate the trimmer at different temperatures. For example, summer brands of lubricants thicken even with a slight drop in temperature. Due to the use of lawn mowers exclusively in the spring-autumn period, oil with summer marking would be an excellent option.

The flash point for trimmer oil must be more than 225C, otherwise the oil will quickly burn out, and the piston group will be subject to intense wear.

Trimmer oil 2 stroke. How much oil to pour into the trimmer?

Depending on the number of engine strokes and the type of oil used, it is necessary to strictly observe the proportions when preparing the fuel mixture.

Gasoline and oil proportions

So, when preparing fuel with mineral oil, the proportions can vary from 1:25 to 1:35. For high-revving engines with synthetic oil, the lubricant and gasoline portion can be 1:50 or 1:80. Fuel preparation consists in pouring a certain amount of oil into gasoline and then mixing.

For long-term storage of a diluted PVC mixture, the container is not suitable, since when interacting with plastic, the solution loses its properties. Long-term storage of the prepared fuel (more than 2 weeks) should not be allowed, which leads to the formation of an oil film and malfunctions in the fuel system.

What to look for when choosing an oil?

Modern two-stroke engines of the lawn mower are fueled with a mixture of AI-92 gasoline and oil marked “2T”. Using a fuel with a higher octane rating will increase the flash point and, as a result, burnout of the lubricant.

Undoubtedly, the best trimmer oil is the one recommended by the manufacturer, but the owner does not always have the opportunity to purchase exactly the “branded” lubricant. Experts recommend Shell Helix Ultra, based on Pureplus technology, which improves the basic properties of the lubricant.

For gasoline trimmers of the German manufacturer Stihl, it is necessary to use oils Stihl HP Ultra, Stihl HP, Stihl HP S. A budget substitute can be Vityaz products, which in their properties are the most similar to the recommended material.

Trimmer oil: selection and proportions

Oil plays a huge role in the performance and durability of the gasoline trimmer, which protects the parts of the cylinder-piston group from rapid wear.

In order for the lawn mower to please its owner with trouble-free operation, a competent approach to maintenance is required. Currently, it is customary to distinguish between two main types of engine by the number of working strokes:

Working principle of two- and four-stroke engines

Two-stroke engines, where oil is added directly to the fuel tank;
Four-stroke engines with separate oil reservoir. An exception in this category is the STIHL 4-MIX engine, which runs on an oil-gasoline mixture, but at the same time has 4 strokes.

However, most trimmers on our market are equipped with powertrains that run on a mixture that has been pre-filled with a fuel tank.

Types of engine oils and their purpose

Oil selection for Benzotrimmer

Gasoline trimmer engine oil is a lubricant used to reduce wear between the rubbing engine components.

The oil composition includes residual hydrocarbons and various additives that improve the properties of the final product. To ensure long-term and trouble-free operation of lawn mowers, experts recommend the use of oils, which in their physical and chemical properties correspond to this type of engine.

Today, it is customary to distinguish between three main types of oils according to the way they are obtained:

Mineral, created in the process of distillation of hydrocarbons;
Synthetic oils obtained by natural gas processing or synthesis;
Semi-synthetic, containing improved mineral oil with the addition of some synthetic components.

In order to prevent mixing of various types, the manufacturer adds a dye to the oils, which shows in the difference in the composition of the lubricant.

Gasoline and oil proportions

So, when preparing fuel with mineral oil, the proportions can vary from 1:25 to 1:35. For high-revving engines with synthetic oil, the lubricant and gasoline portion can be 1:50 or 1:80. Fuel preparation consists in pouring a certain amount of oil into gasoline and then mixing.

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 (as 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 should you try to work on pure gasoline, because in this way you will very quickly “kill” the chain saw.

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 the post-Soviet countries the quality of gasoline is inferior to European, therefore, in our realities it is better to use higher quality gasoline.

As for the proportion of the oil-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 instruction 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 do the same 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 the pistons and cylinders in the engine is much less than in 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. Fill the dry gas canister with gasoline first and then oil. The procedure, on the contrary, is fraught with a low quality fuel mixture, because the oil is denser, it will stick to the bottom of the canister. what a good mixing here.

Be sure to prepare the fuel mixture in the Canister and fill the ready-made special fuel into the gas tank! Never ready and DO NOT mix it 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 fuel 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” 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 there is a dry carburetor in the saws) and now you can leave it in the next operation session.

Unsuitable fuel mixture must be disposed of.
