How To Dilute Gasoline For A Chainsaw

Why gasoline is mixed with oil for refueling chainsaws

It is necessary to dilute gasoline with oil in order to avoid the failure of the internal combustion engine. The reason for this is the design features of the lubrication system for two-stroke motors. These engines do not have an engine oil filling chamber, and if the fuel is filled without lubricant, the crankshaft, piston, bearings and connecting rods will NOT receive lubrication. This will significantly reduce the service life of all the listed parts, therefore, it is prohibited to fill in clean fuel.

Gasoline and oil for the chainsaw must be filled in the appropriate proportions, which makes it possible to effectively lubricate the rubbing parts. Lack of lubricant or its excess will lead to negative consequences in the form of carbon deposits. For the tool to work properly, it is necessary to fill it from the first day of operation of the tool Not only with high-quality materials, but also observe the correct proportions.

For the engine to work properly, the main thing is to fill it with clean fuel without contamination.

Instructions for refueling a chainsaw

Knowing the ratio of the preparation of the petrol-oil mixture, you can start refueling it. The refueling instruction is as follows:

  • First you need to prepare the mixture. Having combined the two main components, you should mix them thoroughly
  • Tool Place on a clean and level surface. Before unscrewing the gas cap, you need to clean or blow off sawdust, dust and dirt
  • Tank neck must point up
  • Install a small watering can in the neck, then pour fuel
  • I control the filling process, since the volume of the tank is small, so it fills up quickly
  • Do not fill up to the full maximum, since when the tank cap is closed, the remaining fuel will splash out
  • After the fuel is poured into the tank, immediately add chain lubricant
  • Fuel consumption and chain lubrication are approximately the same, therefore both tanks must be filled at the same time
  • After refueling, you can start starting the engine

It is better to start the motor not in the place where the refueling was carried out, but to move to a distance of 2-3 m. The tool is ready for work, and you can start to start it. How to start a chainsaw engine, you can read in this material (link).

Gasoline and oil for chainsaws. which is better

Often beginners ask, which one is better to take gasoline for their instrument? In order not to make a mistake in the choice, it is recommended to read the instructions for the tool. In the instructions, each manufacturer indicates the corresponding brand of fuel. If the manufacturer indicates that the octane number should not be lower than 95, then it is not recommended to pour 92 gasoline.

Motor oils for two-stroke engines are produced by the following manufacturers:

  • Stihl
  • Kreissman
  • Sadko
  • Husqvarna

Usually, the ratio is indicated on the lubricant bottle, so it will be difficult even for beginners to get confused with the preparation of the fuel mixture. Under no pretext DO NOT use working off even as a chain lubricant. This will lead to the fact that soon it will be necessary to repair the tool.

Gasoline with chainsaw oil. how to dilute and why it is done

Chainsaws of different companies are based on a two-stroke internal combustion engine, which drives the cutting headset of the tool. To drive the internal combustion engine, proportions of gasoline with chainsaw oil are used. Combining gasoline with oil is a mandatory procedure, so if you just bought a tool, then you need to understand the features of refueling it.

The ratio of gasoline to chainsaw oil

The proportions of oil and gasoline for refueling two-stroke engines of chainsaws of different brands is 40 to 1 or 50 to 1. This ratio is standard, which is used not only by beginners, but also by experienced sawflies. It is this ratio for preparing the fuel mixture that is close to ideal, and provides lubrication of the rubbing parts of the crank mechanism and piston.

How much oil should be poured into gasoline in milliliters? Calculated per ml, the proportion of oil and gasoline 1 to 50 is 20 ml per 1 liter. To prepare the correct mixture, you should put 1 liter of gasoline in a plastic bottle and dilute it with 20 ml of oil. To correctly measure how much oil to pour, you should take a special measuring container and fill it to the appropriate mark. If you plan to immediately prepare 2 liters of fuel, then 40 ml of lubricant must be added to this amount of gasoline.

There are other ratios, which are offered by different manufacturers. These values ​​of the ratios differ insignificantly, but if you subtracted other values ​​in the passport for the instrument, then you need to adhere to them. A value of 1 in 50 or 40 is standardized. Pour 15 ml of oil into 1 liter of fuel in the summer, and in winter topping up at least 20-25 ml. Knowing the recipe for preparing the mixture, you should also figure out what kind of gasoline to pour into the chainsaw?

What will happen if you pour working off into a chainsaw

If you do NOT want your chainsaw to fail at the wrong time, use only high quality fuels and lubricants. It is forbidden to mix working off with gasoline. The reasons for this are the following factors:

  • Other viscosity of the material, therefore, mining is NOT capable of providing effective lubrication of rubbing parts and mechanisms
  • The mining contains small particles of metal and shavings, which, getting into the tank, will cause clogging of the fuel filter and channel. If the grease gets into the cylinder together with small particles, they will leave their mark in the form of accelerated wear of the piston rings.
  • Generation of a large amount of black smoke, which indicates burning oil

Filling in surrogate materials It is impossible not only to the gasoline tank, but also to the chain lubrication tank. What happens if you use the development in the tank for chain lubrication can be seen on.

Using the instructions, you can independently prepare the correct fuel mixture on which the chainsaw will work. Improper dilution of the fuel mixture will not only reduce tool life, but also reduce tool performance.

How to dilute gasoline for a Chinese chainsaw. What gasoline to pour into a chainsaw?

Manufacturers strongly recommend using only high-quality gasoline for chainsaws, with an octane rating of at least 92 and ethanol NOT more than 10%. It is not recommended to use opaque gasoline containing impurities. they will quickly clog the fuel system and engine.

IMPORTANT: the gasoline mixture for the chainsaw is not necessarily prepared just before pouring into the tank. this can be done in advance. over, many manufacturers produce ready-made containers with several compartments, for example, for gasoline and oil or gasoline, oil and ready-mixed mixture, and also complete such containers with a special measuring syringe. With its help, oil is collected in the chainsaw in the proportion that is required. But if the mixture is prepared in advance, then its maximum storage period should NOT exceed 10 days. over time, the octane number of gasoline decreases, and due to the fact that part of the gasoline evaporates from the mixture, the proportion of oil and gasoline for the chainsaw changes.

Is it possible to pour 95 gasoline into a chainsaw?

Almost 75% of manufacturers in the passport for chainsaw indicate that it is necessary to use AI-92 gasoline. The owners of such equipment, who first encounter it and DO NOT know what gasoline is needed for a chainsaw, draw parallels with car engines and conclude that the higher the octane number, the better. As a result, I don’t understand how to properly dilute gasoline for a chainsaw, dilute oil and AI-95 gasoline.

The thing is that an increase in the octane number is achieved by introducing various additives into gasoline, as is done in AI-95 and AI-98 gasoline. For two-stroke engines, additives are harmful due to their special design, so you need to use AI-92 gasoline, especially in our country. Firstly, it is correct and will extend the life of the motor, and secondly, it is cheaper. But for some manufacturers, for example for Stihl, AI-95 can also be used, but it is better to take it at good proven gas stations.

How to dilute gasoline for a chainsaw?

Before pouring fuel into the tank, it is necessary to prepare a gasoline mixture. The ratio of oil to gasoline for a chainsaw is regulated in strict proportions. as a rule, they are indicated in the owner’s manual. In the event that you do not know how much oil to pour into gasoline for a domestic chainsaw, it is recommended to use a ratio of 1:15. 1:20. That is, for 1 liter of gasoline use 50-70 ml of oil.

As for imported equipment, the proportions are completely different. For example, how to dilute gasoline with 2 kW Husqvarna chainsaw oil? To do this, look at the instructions and see that the manufacturer recommends using a 1:50 proportion, i.e. For 1 liter of gasoline, NOT more than 20 ml of oil is used. If the passports have comments (lost, torn, etc.), use the Internet or contact the service center. this way you will find out exactly how much oil you need to fill in gasoline for a chainsaw. An increased amount of oil threatens with increased carbon deposits and cylinder clogging, which will lead to fracture of the piston rings and a decrease in compression, moreover, it is expensive. If the amount of oil for chainsaws in the mixture is low, this will lead to overheating of the engine and a sharp decrease in its resource.

If you do not know how much oil to pour into a Chinese chainsaw, and you have passports at hand, then this proportion is approximately 1:25, that is, 40 ml of oil per 1 liter of gasoline. In general, the amount of oil directly depends on the layout. the tighter all units are installed, the less oil is needed.

Before preparing a gasoline mixture for a chainsaw, you must first pour gasoline into the canister, and only then add oil, not otherwise. Otherwise, the more viscous oil will stick to the walls and bottom of the canister and dissolve worse, which will violate the correct proportions of gasoline and chainsaw oil.

How to refuel a chainsaw

Consider how to refuel your chainsaw. Failure to feed the saw correctly can pose a threat to the life and limb of the operator.

There are rules that must be followed when refueling the saw:

  • Oil and fuel mixture must not be spilled;
  • The place where the saw will be refueled must be level;
  • The place must be more than 2 m away from the area where the device will be used;
  • The site must be located away from fire; no smoking in this place;
  • While the fuel tank is filling, you need to fill the oil tank, which is intended for automatic chain lubrication; you can distinguish between containers by special icons;
  • Before pouring, wipe the container necks with a rag;
  • During operation, grease and gasoline must not be spilled, so you need to be careful when unscrewing the canister caps; when refueling, it is better to use a funnel;
  • Care should be taken when tightening the latch cap;
  • Experts advise NOT to fill the container completely, but to leave some free space.

During the operation of a properly refueled chainsaw, it is necessary to regularly check the tightness of the containers and the operation of the engine. If the chain gets too hot, or gasoline is consumed too quickly (faster than oil), this should alert you. Before starting work, the chainsaw is run in.

With proper operation of the chainsaw, 1 tank of gasoline should be enough for 30 minutes of operating the device at maximum load. When gasoline runs out, there is still grease in the second container, but in a small amount.

What oil to pour into a chainsaw?

It is strictly forbidden to use the oils that are used in automobile engines. you need a special two-stroke oil for a chainsaw recommended by the manufacturer. Manufacturers themselves DO NOT produce lubricants, with rare exceptions, but cooperate with all well-known brands and often offer their products under their own label. Therefore, in the passport you will definitely find a Mention in which 2-stroke oil for chainsaws is suitable for this particular model.

Why you need to mix oil and gasoline

When using the saw, gasoline should always be mixed with oil. The reason for this is the design features of a two-stroke internal combustion engine. It does not have a dedicated lubrication system for parts (as in other GIS) and, accordingly, its cylinders with O-rings, crankshaft, bearings and connecting rods Must be lubricated directly in the process of obtaining fuel.

Review: Which gasoline to use 92 or 95?

Fuel selection

Which fuel to choose for a chainsaw is a no-brainer, the success of the unit directly depends on it. According to the existing canons, good gasoline for a chainsaw is considered NOT leaded, but high-octane from a trusted manufacturer. The cleaner the fuel, the better. If gasoline has been stored in the Canister for a year or a year and a half, this will adversely affect the nature of the device’s operation, therefore, the substance should be prepared before the very start of work.

It is important to monitor that there is no alcohol in the fuel, any additives that can disrupt the functioning of the power plant. Experts are still debating which is better than 95 or 92. The first has more stable detonation rates, but most often the 92 is still used. The reason is simple: questions often arise by the 95th, there are a large number of various additives in it, which have a bad effect on the operation of the saw engine. Micro-knock (piston impulse in the opposite stroke) occurs, which occurs practically at every revolution of the crankshaft. If the octane number is even higher (98), then the micro impacts will become even more intense.

The consequences of improper gasoline on the quality of the unit can only be negative:

  • The mechanism will be difficult to start.
  • The power will be minimal.
  • Parts will wear more intensively.

Advantages and disadvantages of oil

Any quality machine oil has its pros and cons

Any quality machine oil has its pros and cons. Some experts say that any chainsaw oil will work. This is not entirely true, almost any substance can be used for the Hurstavna chainsaw, but for the Stihl chainsaw, only gear oil is required. When choosing, you need to know the shade of the oil well, a two-stroke engine requires a composition, which has a reddish, bluish or greenish tint.

To prepare the mixture yourself, you need to use a heat-resistant grease, which has a well-known brand name.

Seasonality affects product density:

  • Air temperature.
  • Humidity.
  • Solar radiation intensity.
  • Pressure.

What are the features of different oils, you can find out precisely by carefully examining the label on the container. In the absence of instructions or labels on the packaging, you should refuse to use such a substance. At the same time, the performance characteristics of the oil should not change dramatically with a temperature difference.

You should not use any substitutes, often there are counterfeit products among them (up to 20%). It is quite difficult to distinguish a fake, you need to have special equipment.

It is recommended to store fuel in metal containers. Prepares fuel mixture best in Canister.

There are a large number of oils and each has its own characteristics.

The consistency is done in the ratio:

The performance characteristics of mineral or organic oils intended for the chain itself are not suitable for preparing the fuel mixture. The finished product is poured into the tank (up to half), then mixed (the container must be hermetically closed). Thus, a homogeneous composition is obtained. Fuel is better not ready ahead of time, it loses its functional properties quickly enough. At room temperature, flammable liquid deteriorates within two weeks.

How much oil is required to add to gasoline?

Types of oils used for dilution in gasoline

Chainsaws have oil pumps, so the combustible mixture alone cannot be used. You should carefully read the instructions that are attached by the manufacturer to each product. There is a lot of information on the Internet, it is NOT difficult to find it.

If there is no lubrication, the saw will fail after a short time. It is recommended to do preventive maintenance of the unit, fill in properly diluted fuel, in this case the tool will function for many years.

If we take, for example, a Husqvarna chainsaw, then unleaded gasoline with the first addition of grade 92 is suitable. If the composition has a greenish tint, this indicates that the product is a premium class. AI-92 is the optimal product, which can be suitable for such a device. On average, professionals advise adding 20 to 50 ml of machine oil per liter. If the power of the unit is one and a half kilowatts, then only 25-27 ml of oil is required.

How to dilute engine oil and gasoline, in what proportions? This question arises for all users. First you need to stock up on containers:

  • Measuring liter bottle
  • Dispenser and syringe
  • A watering can, which will allow you to pour the substance into the tank

The process of mixing oil and technological gasoline is simple. It is important to observe safety precautions so that static electricity does not accumulate, not a drop of water gets into the fuel.

Types of oils used for dilution in gasoline

What proportions should be done? The engines are mostly two-stroke, so the mixture is usually 1:50. Russian-made chainsaws function with products of the following brands:

  • M8-B
  • M-12TPU
  • TP
  • MGD-14M

For foreign analogues, it is permissible to use two liters of gasoline per 80 grams of oil. Foreign saws are distinguished by economical fuel consumption, the proportions of oil in them vary from 40 to 49 shares.

Oil shades can vary significantly, this should be taken into account during operation. For example, HP produces reddish engine oil. If the composition has a greenish (sometimes blue) tint, then this is a sure sign that the product is synthetic premium. The quality in such compositions is high, the price is also rather big.

Instructions: How to properly dilute gasoline with chainsaw oil

Mineral oils are inexpensive, so they are most often used. Synthetic oils must be filled if there are significant temperature fluctuations, they do NOT generate carbon deposits, they have additives useful for dynamic nodes.

The product of the Husqvarna company is considered the highest quality, the second place is the Lukoil machine oil.

The advantages of THESE oils:

  • Low consumption.
  • Maintaining quality.
  • Ability to maintain technological properties for a long time.
  • Can work in extreme conditions.
  • No toxins.
  • Minimum amount of carbon deposits.

Many professional tools use a lubricant made using API-TB technology (USA). Also popular are products that are produced according to the JASO-FB method (Japan).

Let’s mix oils from different brand manufacturers with similar characteristics. Mineral and synthetic oils are incompatible. The best oil for household chainsaws is considered “Standard”, technical fluid “Ultra” is optimal for professional equipment.

Some oils can successfully replace each other. For example, substances Produced by Husqvarna and Stihl. Lubricant for scooter engines or motor boats Not suitable for chainsaws, the oil quality is poor. If the proportions of oil and gasoline are not maintained, the tool will quickly fail due to the abundant formation of carbon deposits.

  • Chain lubrication element.

Each chainsaw requires high-quality fuels and lubricants, it is they who ensure the long-term productive operation of the unit. What gasoline for the chainsaw to fill, in what proportions?

Simple oils are suitable for domestic chainsaws, foreign chainsaws need more complex fuel mixtures, which have been thoroughly cleaned.

What gasoline should you use for your chainsaw? How to breed it correctly?

The chainsaw is simple in design and is sometimes needed in private households. The device cannot work fully if you do not use the correct fuel mixture, which you should be able to prepare.

Advice

Tips and life hacks are extremely useful in practical work, consider some of them:

  • It is convenient to use canisters with dispensers, while experienced people filter gasoline through suede. The cleaner the fuel, the better the carburetor will work.
  • Gasoline can actively evaporate, especially at high temperatures, a suspension falls out at the bottom of the canister, which must not be poured into the engine.
  • Recommended fuel is ready for no more than three operational refueling.
  • The quality of the fuel can be affected by the material of the container, especially PVC materials react actively.
  • If the combustible mixture was poured of poor quality, the chainsaw may be removed from the warranty.
  • During operation, the tightness of containers and the rhythmic operation of the engine should be tested.
  • One of the first signs of a malfunction is an unnecessary heating of the circuit.
  • Before subjecting the tool to severe stress, it should be tested at idle speed.
  • The tank is enough when working for half an hour.
  • There is still grease (residues) in the second container when it has run out in the tank.
  • If a large amount of smoke is generated during operation, this means that the fuel is of poor quality.
  • During operation of the unit, do not approach open flames.
  • (Distance up to 2 meters).
  • Do not add fuel. “under the rim “, leave some space.

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.

Standard proportions

First of all, it is necessary to take into account the information that the manufacturer recommends, since in the event of a failure of the lawn mowers, you can present your claims to him, and not to a third-party source. If there is no instruction in the passport, and even more so if there is no passport, we recommend that you look for another trimmer model in a more reliable seller.

For all other cases, when you have a lawn mower model in your hands and there is no way to find out its technical features, there are standard proportions of the Most probable fuel mixture components for a two-stroke engine. Basically, for THESE units, AI-92 gasoline and a special synthetic oil are used, which contains a solvent for better mixing with fuel. This oil evaporates slowly and has the ability to completely burn out in the cylinder, Do not leave carbon deposits.

The standard ratio of synthetic oil to gasoline is 1: 50. This means that 5 liters of gasoline need 100 ml of oil, and in accordance with this, oil consumption per 1 liter of gasoline is 20 ml. Knowing the amount of oil required to dilute 1 liter of fuel, you can easily calculate any rates when preparing fuel for the trimmer. When using mineral oils, a ratio of 1: 40 is most often the standard. Therefore, 1 liter of fuel will require 25 ml of such oil, and for a 5-liter canister. 125 ml.

When working with lawn mowers, a person with little experience in operating such equipment will not be difficult to determine and correct the actual amount of oil required for a particular model. You should only pay attention to Exhaust gases (their color, odor toxicity), cycle stability, engine heating and developed power. details about the consequences of incorrect mixing proportions of gasoline and oil can be expected in another section of the article. There are variants of lawn mowers running on AI-95 gasoline. This should also be considered.

Mixing rules

And now about how to mix the components correctly. However, it would be more logical to start with an analysis of common, but absolutely unacceptable mistakes, which many owners of this mowing unit “sin” with. The following actions are considered as mixing errors.

  • Adding oil to the fuel already in the mowers’ gas tank. Similarly, a homogeneous fuel mixture will NOT work. Perhaps it will work, if only then shake the trimmer for a long time. But it is unlikely that someone will do this by taking the weight of the unit.
  • First pour oil into a mixing container, and then add gasoline to it. Gasoline has a lower density than oil, so if it is poured into the oil, it will remain in the upper layer, that is, natural mixing will NOT occur. Of course, it will be possible to mix later, but much more energy will be required than if it were done the other way around. pour oil into the filled gasoline.
  • Ignoring accurate measuring instruments for taking the required quantities of ingredients used. In other words, diluting the amount of oil or gasoline “by eye” is a bad habit when operating motor vehicles.
  • Take empty drinking water bottles for preparation of the fuel mixture. Such a container is made of too thin polyethylene, which can be dissolved in gasoline.

Considering all of the above, we recommend using the following rules when mixing a fuel mixture for two-stroke trimmer engines.

  • Use only clean containers made of metal or special plastic for storage of gasoline, oil, ready-made fuel mixture and its preparation.
  • Use for filling gasoline into the LEIKOME dilution container in order to avoid spilling, and for adding oil. in a measuring container with volume risks or a medical syringe for 5 and 10 ml.
  • First, pour gasoline into the canister for preparing the fuel mixture, and then oil.
  • To dilute the mixture, first pour only half of the planned volume of gasoline into the container.
  • Next, add the entire amount of oil required to prepare the mixture to the gasoline.
  • Mix the contents of the dilution container thoroughly. It is best to stir by making circular movements with a tightly closed container. You should not stir the fuel inside the canister with any foreign object, since it is not known what material this object is made of, what reaction it can enter into with an ingredient in the mixture, how clean it is.
  • Add the rest of gasoline to the mixed mixture and mix thoroughly again.
  • You can refill the fuel tank of the lawn mowers.

It must be borne in mind that the ready-made fuel mixture does not have to be stored for more than 14 days, since it loses its properties, stratifies and evaporates, which leads to changes in proportions, and therefore, deterioration of trimmer performance.

Consequences of violation of the ratio

How accurately you will observe the proportions of the oil-gasoline mixture recommended by the manufacturer depends on the service life of the motor scooter engine. The fact is that the fuel mixture enters the cylinders in the form of gasoline-oil mist. And the task of the oil composition is to lubricate the moving and rubbing parts and surfaces of various parts in the cylinder. If it suddenly turns out that there is not enough oil, but somewhere it will not be enough at all, the parts touching dry will begin to damage each other. As a result, scuffs, scratches and chips are formed, which will certainly lead to complete or partial engine failure (for example, it can jam).

In the opposite case, when too much oil enters the engine, it does NOT have time to completely burn out, settling on the cylinder walls and turning over time into solid particles. coke, slag and the like. As you might guess, this also leads to engine failure. The most important thing is that you must not allow. even a single violation of the proportion towards the lack of oil. It is better to pour a little oil 10 times than not to top up just once. It often happens that this time is quite enough to break the engine.

Gasoline to lawn mower oil ratio

lawn mows are a fairly common technique for combating weeds in summer cottages, in road gardens and housing and communal services. These devices have two more names. trimmer and lawn mower. These units differ in their engines. The more expensive ones have four-stroke engines, all the others have two-stroke engines. Of course, the latter are the most popular among the population, since they are simpler in design, and lighter in weight, and much cheaper than their four-stroke competitors. However, two-stroke models are inconvenient in that the fuel mixture for them must be prepared manually, maintaining a strict dosage between gasoline and oil. In four-stroke analogs, the mixing of THESE components occurs automatically, you only need to fill the gas tank and oil tank with the corresponding substances. Let’s consider the issue of the correct refueling of two-stroke lawn mowers, since it depends on how effective and long the operation of such a unit will be.

How to choose for lawn mowers?

For two-stroke engines, lawn mowers use AI-92 or AI-95 gasoline. Most often. the first of the named. There is always information about this in the technical data sheet of the product. If, for some reason, it is not known exactly on which gasoline the trimmer should work, you can choose it by testing both brands of gasoline in action. Global changes in the engine will not happen from this, and it is quite possible to determine what kind of gasoline and or another model of the unit “likes” more, according to some factors. This will be shown by the developed power, and throttle response, and engine heating, as well as its stable operation at all speeds.

But it is much more difficult to determine the proportions of oil to a certain volume of gasoline. In this case, you need to know at least something in the equipment manufacturer. And already according to the standard proportions for this manufacturer, select the proportion for a specific model, taking into account the type of oil.

For example, for Chinese low-power trimmers, two ratios are mainly used. 1: 25 or 1: 32. The first is for mineral oils, and the second is for synthetic oils. In the choice of standard proportions for lawn mowers of European and American manufacturers in connection with the type of oil, we have already told you earlier. According to the class of oils for household trimmers, you need to use TB oil according to the API classification. For more powerful. class TS.
