The most different brands of chainsaws are acquired by the owners of country houses. Miracle technique is indispensable for harvesting firewood and erecting outbuildings. Those who have been using this tool for a long time know all the subtleties of its maintenance. But beginners should definitely learn how to dilute gasoline with oil for a chainsaw. This will be discussed in the article.

Characteristics of household chainsaws

The speed of the chain depends on the speed of the engine, which is cooled by air. A separate oil tank is provided for lubrication and cooling. With an increase in the frequency of its rotation, the automatic oil supply also increases. For normal operation of the chainsaw, it is necessary to control the contents of two tanks. for the operation of the engine and the chain.

In what proportions should liquids be mixed?

Each manufacturer of chainsaws determines their proportions to obtain a gasoline-oil mixture and indicates this in the technical passport, which is attached to the instrument upon purchase. The proportions of gasoline with oil for domestic chainsaws are most often recommended in a ratio of 1:15 or 1:20. In order to calculate how much oil is needed per liter of gasoline, you need 1000/15 = 65 ml and 1000/20 = 50 ml. In the first case, 65 are added to each liter of gasoline, and in the second. 50 ml of oil. For imported equipment, the proportions are slightly different.

For a Husgvarna chainsaw, the engine power of which is 2 kW, the manufacturer advises using a ratio of 1:50, i.e. 20 ml of oil is added to each liter of gasoline. In Chinese-made saws, pour 40 ml of oil per liter of gasoline at a ratio of 1:25. It should be remembered that with an excess of oil in gasoline, soot increases, the cylinder becomes clogged, piston rings are damaged and compression is reduced. If there is a lack of oil, the engine overheats and the productivity of the tool sharply decreases. When the documentation is lost and you don’t know how to mix gasoline with chainsaw oil, you can contact the service center for the necessary information.

What kind of gasoline to pour?

The quality of the combustible material affects the engine traction, speed and coordination of the work of all elements of the system. In different models of saws, fuel with a different octane number is poured. Local tool manufacturers advise taking low-grade AI-80 fuel. Sometimes they make a mixture of AI-80 with AI-92. For foreign models, the octane number should not be less than 90, therefore, AI-92 and AI-95 gasoline are recommended. In all cases, unleaded fuel must be used so that it does not contain lead, which adversely affects the details of the tool. How to breed gasoline with chainsaw oil? It is necessary to be guided by recommendations of the manufacturer. Otherwise, it is easy enough to damage the tool and violate all factory settings.

Should I use the AI-95?

Whoever only gets acquainted with a chainsaw and makes attempts to carry out some chores, instead of AI-92 fuel, refuel it with AI-95, believing that it is of the best quality. Gasoline with an octane rating of 95 is obtained from AI-92 by adding various additives. Special additives have a negative effect on two-stroke engines due to their design features. They accumulate on the inner walls of the instrument and eventually peel off, disrupting its operation. Therefore, experts advise buying only AI-92 for preparing a mixture for chainsaws.

Chainsaw Mixing Oil

To lubricate the internal parts of a gasoline engine, special oils are used that have the following properties:

• High quality cleaning. narrow carburetor channels should not be clogged with impurities of the fuel mixture.
• Must have low smoke during combustion. the oil burns together with gasoline in the saw engine. A large amount of smoke negatively affects the exhaust system and the health of the owner of the saw.
• Do not form excess carbon deposits. they adversely affect the operation of the tool, settling on the piston, and clog the exhaust system.

Using poor-quality oil, the owner of the saw may encounter serious problems, which will result in expensive repairs. How much oil to pour in gasoline for a chainsaw is indicated by the manufacturer on the package. Adhering to this dosage is mandatory, since the wrong proportions adversely affect the life of the tool.

The main brands of motor oils for chainsaws

Leading chainsaw lubricant companies are Stihl and Husgvarna. The following oils are used for saws:

• Stihl HP is a mineral lubricant for tools of the same brand. It has a red color, is available in different packaging, even for single use, which is very convenient.
• HP Ultra. is made on a synthetic basis, has improved qualities, is used at low temperatures.
• Vitals Semisynthetic. designed for budget models, used year-round.
• Husgvarna HP. semi-synthetic, equipped with additives to compensate for the low quality of gasoline. Suitable for use in technology and other brands.
• Champion Jaso FD. provides reliable protection for all engine parts.

In the market for two-stroke engines, a large selection of products from different manufacturers. How to dilute the chainsaw oil is indicated on the packaging. Buying better products from well-known companies, this will help keep the tool in working condition longer.

How to mix gasoline with chainsaw oil?

To mix the ingredients you need:

• Use a clean, dry container, a measuring cup, and a graduated bottle.
• It is necessary to mix in a separate container, and not in the saw’s gas tank.
• First, fill in half of the gasoline, then oil, shake everything well, add the second part of gasoline and mix again.

Every tool owner should know how to mix gasoline with chainsaw oil. However, the right proportions are not yet a guarantee of a good mixture. It is important to choose quality products so that gasoline and oil are homogeneous fluids and do not contain sediment. It is better to prepare the mixture before starting work. Although according to the standards, the finished fuel and lubricating fluid can be stored for a month, but its properties deteriorate over time.

Chainsaw "Stihl"

For the Stihl saw, the manufacturer recommends the use of unleaded gasoline of the AI-92 or AI-95 brand. In addition, the company also produces oils for the preparation of fuel for its tool. If you purchased a Stihl chainsaw, how to dilute gasoline with oil? In the attached instructions, it is recommended to use the content in a mixture of gasoline and oil in a proportion of 1:50. This means that 20 ml of oil is added to each liter of gasoline, and best of all, by Stihl.

The relationship should not be violated; this will cause a malfunction in the tool. Often, in conjunction with the equipment, the manufacturer also applies a special canister with the applied divisions and two holes into which the necessary ingredients are poured for mixing.

Huter chainsaw: how to dilute gasoline with oil?

The German company Huter in the Russian market since 2004. It mainly supplies garden equipment. The chainsaws of this company are intended for domestic use only. For the preparation of the fuel mixture, manufacturers recommend the use of high-quality oil, which is suitable for two-stroke engines, cooled by air, in accordance with API TB or API TC classification. Mixing gasoline must be taken AI-92 unleaded. The ratio of the components in this case is 1:40, i.e., 25 ml of oil is taken per 1 liter of gasoline, when no other data are indicated on the bottle with oil. Mixing is carried out in a separate container in the specified proportions, and only then the mixture is poured into the fuel tank.

To do this, take a bottle with divisions and a medical syringe without a needle. All ratios must be strictly observed.

How to use chain oil?

The lubricant for chain lubrication is recommended by the manufacturer and is indicated on the instrument data sheet. Usually these are branded products with high quality. While the chainsaw is new, it is necessary to apply it. Otherwise, if the tool breaks, it is removed from the guarantee and repairs are carried out at the user’s expense. Subsequently, the oil is replaced with a cheaper one, but it must comply with the following requirements:

• protect the chain from corrosion;
• increase wear resistance, reducing friction;
• do not form soot;
• keep the ability to work with the tool in a wide temperature range.

For long-term operation of the chainsaw in good condition on oil for the chain, it is better not to save.

Conclusion

The article describes in detail how to dilute gasoline with oil for a chainsaw. When preparing the mixture, try to strictly observe all the proportions so as not to harm the technique. When running a new tool, remember to add 20% more oil in hot weather than indicated in the instructions.

Hello! This article will focus on the correct ratio of oil and gasoline for a chainsaw. This is perhaps the most important thing to know when operating this device. Lack of oil will lead to excessive friction, and too much of it. to excessive occurrence of soot and overheating. As a result, both of these will lead to a quick engine breakdown. Repair can get up at half the price of a new chainsaw.

In addition to the correct proportion, we will also discuss other important things that will allow you to serve your chainsaw for as long as possible. which gas to use, which oil to use, dilution methods, shelf life of the finished mixture, etc. so I advise you not to quit reading the article after the section on proportions , since further information will also be useful to you.

Correct proportions

So, I won’t be going around for a long time, but right away I will turn to the numbers. The most common dilution proportions are 1:50 and 1:40. That is, one part of the oil is poured onto 50 or 40 parts of gasoline. For those who do not understand, I will explain in more detail. We take one liter of gasoline and divide it by 50 or 40, respectively. As a result, we get the right amount of oil per liter of gasoline. That is, one liter is 1000 ml. Divide 1000 ml by 50, we get 20 ml of oil. Divide by 40, we get 25 ml. That is how much oil you need to add to one liter of gasoline.

But you will say that you don’t know what proportion should be on your chainsaw. Well, if you lost the instruction or for some reason there is no information about the proportion, then you can use the following rules:

• if the chainsaw and oil are from the same brand (for example, Stihl chainsaw and Stihl oil), then dilute gasoline with oil in the proportion indicated on the oil (usually 1:50);
• if chainsaw and oil of different brands, then observe a proportion of 1:40;
• if the brand is the same, but there is no information on oil, then breed in a proportion of 1:40;
• if you don’t know anything at all. you don’t know the brand of the chainsaw or the oil. Then you still breed in the ratio 1:40. The main thing is to know at the same time that the oil is exactly suitable for two-stroke chainsaw engines.

If the saw is new and is being tested, the amount of oil for the first three refueling of the fuel tank is recommended to be increased by about 20%. That is, the proportion 1:50 turns into 1:42, and 1:40 at 1:33. Or 24 or 30 ml of oil per 1 liter of gasoline, respectively. Well, I note here that in addition to increasing the amount of oil in the fuel mixture, no more break-in measures with a chainsaw are needed, unless otherwise specified in the instructions. That is, it is not necessary, for example, to leave it to work for a long time at idle or to cut it not at full speed, since this will lead to its overheating and faster failure. Always cut at maximum speed. And after the development of three fuel tanks (meaning the chainsaw tank), go to the usual proportions of 1:50 or 1:40.

But sometimes it happens that the manufacturer indicates a different proportion compared to those that I cited above. For example, 1:25 or 1:32. In this case, it is necessary to observe precisely these proportions. Although if you know about them, then what did you forget in this article?

Which oil to use?

Oil, as already mentioned, should be for two-stroke engines. At the same time, it should be suitable specifically for chainsaws, as indicated on its packaging. There are simply two-stroke oils, for example, purely for outboard motors or scooters. They should not be used, since the operating mode of such a technique is not so intense, therefore, the oil requirements are somewhat lower.

At the same time, there are oils where it is indicated that they are suitable for both chainsaws and boat engines and scooters. Such oil can be used. But if it is only for outboard motors or scooters, then it is impossible.

Oil producers

One of the best oils, admittedly by most experts, is produced by Stihl, the one that also does chainsaws very well. Therefore, if you have an expensive chainsaw, then it is better not to save by buying cheaper oils.

Another major global manufacturer of chainsaws. Husqvarna. also produces two-stroke oil of the same name. But many users noted that when applied to other brands of equipment, it leads to excessive smoke, and in general chainsaws do not work at full capacity. At the same time, the Husqvarna technique itself works perfectly on such oil. Therefore, if you have a Husqvarna chainsaw, then buy the same oil for it. For other equipment it is better not to take it.

There are also well-known world brands producing various malas, including push-pull ones. For example, Ravenol. Oil from such manufacturers can also be bought without fear.

There are oils produced. In principle, they are not bad if the saw is used in domestic use. That is, of course, it will slightly reduce the life of the chainsaw, but in everyday life you will not notice this, since the chainsaw engine in any case in such sparing operating conditions serves for many years. For professional activities, I do not recommend taking such an oil.

Oil color

Two-stroke engine oil is usually red, blue or green. This does not affect the performance properties. The dye is added only so that in the future you do not confuse the gas-oil mixture with pure gasoline and pour it somewhere where it is not supposed to be poured.

Mineral or synthetic?

Yes, as with automobiles, there are both mineral and synthetic oils for chainsaws. Due to the lower price, in most cases, mineral oil is used. However, synthetic provides a longer service life of the chainsaw, since there is no soot left on the cylinder walls with it.

But do not be afraid of mineral oil if you can not get synthetic. With him, even carbon deposits are, but not so much. Nevertheless, the service life of a saw with such oil will be slightly lower (but not catastrophically).

What you just can’t do exactly is to start using synthetic oil after a mineral water has been used on your chainsaw for a long time (more than 100 hours). This is due to the fact that synthetics will wash away the accumulated soot and it can get into pieces where it is not necessary. Therefore, if you started to use mineral oil initially, then use only it.

Which gasoline to use?

Gasoline for modern chainsaws is better to use AI-92. 95th is better not to apply. Firstly, because the saws are configured to work precisely on 92nd gasoline. And, secondly, 95th gasoline is obtained by adding special additives to gasoline with a lower octane rating. And as experts say, this is not good.

In general, fill in the 92nd gasoline and you will be happy. Just don’t stock up on him, because with long months of storage, his octane number drops.

In general, they say (they say!) That our refineries can produce in their pure form only the 80th gasoline. But already due to additives they bring it to the 92nd and 95th. In the 95th, naturally there are more additives. So, with long-term storage, these additives "evaporate" and gasoline again becomes 80th. Whether it’s true or not, I don’t know, but I learned this information back in 2009 at one of the gas service workshops from the head of the Russian service department of one of the gas technology manufacturers. If this was true, then maybe for today (2018) the situation has improved.

In any case, it is better to buy gasoline at proven gas stations where you have already refueled and everything was fine.

Shelf life of the finished fuel mixture for chainsaws

So, clean gasoline can be stored for not very long, and the finished fuel mixture is even less. Some manufacturers indicate that diluted storage is allowed for up to one month.

But experts recommend storing no more than 8-10 days.

Just as soon as you mix, the oil immediately begins to gradually lose its properties. As a result, in just a few days this fuel mixture is not the same as it was originally. What can we say about storage for more than a month.

Therefore, do not cook the mixture for the future. You need to cook as much as you intend to use for your upcoming work. How much you need to procure, only experience can tell. If you don’t have enough yet, prepare no more than one liter of fuel mixture. If it is not enough, then cook again. this will not be long. If it remains, then it will not be so large as to regret it.

Store the finished fuel mixture in a closed, opaque container. Or, if the container is visible, then put it in a dark place. The container must be petrol resistant. For example, plastic bottles from various drinks (“one and a half”) will not work. Their plastic is corroded by gasoline and all this muck gets into the engine.

You can use special metal or plastic canisters for combustible materials. Or simply use an empty canister from under any used oil, rinsing it several times with clean gasoline from the inside. Glass containers are also suitable, but it should be borne in mind that they are easy to break.

How to breed correctly?

The numbers of dilution proportions are not in vain given with such accuracy. That is, it does not say that “take about so much oil. ” The exact proportion cannot be observed by eye, so you will have to use something that will allow you to measure the exact amount of oil and gasoline.

Complete with some inexpensive chainsaws is usually a measured tank with risks. As a rule, it has several scales for different proportions. Or one, if the manufacturer implies that this tank will only be used with a saw, with which it comes with the kit. There should be two horizontal risks on this scale. The bottom shows the level to which you need to pour gasoline. The top is the level to which the mixture should reach after adding oil to gasoline.

To more accurately measure the oil, you can use a medical syringe. Preferably not less than 20 ml.

In general, pour gasoline into the measuring container, add the right amount of oil measured by a syringe and shake.

The preparation of the mixture must be done in a separate container, and not directly in the tank of the chainsaw. Otherwise, the oil, not having time to dilute with gasoline, can get into the carburetor, which will complicate the factory, up to the need to remove the carburetor and clean it.

Conclusion

Well, I think this is all the necessary information on the fuel mixture for chainsaws. Armed with it, you guarantee yourself a long engine life of your chainsaw. I also have a lot of other useful information on petrol and power tools on my site. you can read it. And I will end this article. goodbye and many years of service to your chainsaw!

The chainsaws of various companies are based on a two-stroke internal combustion engine, which drives the cutting headset of the tool. To activate the internal combustion engine, the proportions of gasoline and chainsaw oil are used. Combining gasoline with oil is a must, so if you just bought a tool, you need to understand the features of its refueling.

Why gasoline is mixed with oil for refueling chainsaws

Dilute gasoline with oil to avoid failure of the internal combustion engine. The reason for this is the design features of the lubrication system of two-stroke engines. In the design of such engines there is no chamber for pouring motor oil, and if 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 of these parts, therefore it is forbidden to fill clean fuel.

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

For the engine to work properly, the main thing is to fill in clean fuel without pollution.

The ratio of gasoline and oil for chainsaws

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 filers. It is this ratio for the preparation of the fuel mixture that is close to ideal, and provides lubrication of the rubbing parts of the crank mechanism and piston.

How much oil do you need to pour in gasoline in milliliters? Per ml ratio of oil and gasoline 1 to 50 is 20 ml per 1 liter. In order to prepare the right mixture, pour 1 liter of gasoline into 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 it is immediately planned to prepare 2 liters of fuel, then 40 ml of lubricant must be added to this amount of gasoline.

There are other ratios offered by different manufacturers. These values ​​of the ratios differ slightly, but if you subtracted other values ​​in the passport to the tool, then you need to stick to them. Values ​​of 1 to 50 or 40 are standardized. Pour 15 ml of oil per 1 liter of fuel in the summer, and in the winter add at least 20-25 ml. Knowing the recipe for the preparation of the mixture, you should also figure out the question of which gasoline to pour into the chainsaw?

Gasoline and chainsaw oil. which is better

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

Engine oils for two-stroke engines are produced by such manufacturers:

Usually, the ratio is indicated on the bottle with lubricant, so it will be difficult even for beginners to get confused with the preparation of the fuel mixture. Under no circumstances should you use refining even as chain lubricant. This will lead to the fact that soon it will be necessary to carry out tool repairs.

Instructions for refueling a chainsaw

Knowing the ratio of the preparation of the benzo-oil mixture, you can proceed to refuel it. The fueling instruction is as follows:

1. First you need to prepare the mixture. Combining the two main components, mix them thoroughly.
2. Place the tool on a clean and even surface. Before unscrewing the gas tank cap, it is necessary to clean or blow off sawdust, dust and dirt
3. The neck of the tank should look up
4. Install a small watering can in the neck, then pour fuel
5. Control the refueling process, as the tank volume is small, so it quickly fills up
6. Fill up to a full maximum, as when you close the tank lid, the remaining fuel will splash out
7. After the fuel is poured into the tank, immediately add lubricant to the chain
8. Fuel consumption and chain lubrication are approximately the same, therefore both tanks must be refilled
9. After refueling, you can start to start the engine

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

What will happen if you pour mining 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 mining with gasoline. The reasons for this are the following factors:

• Another viscosity of the material, so mining is not able to provide effective lubrication of rubbing parts and mechanisms
• The mining contains small metal particles and chips, which, falling into the tank, will lead to clogging of the fuel filter and channel. If grease enters the cylinder with small particles, they will leave their mark in the form of accelerated wear on the piston rings
• Emission of a large amount of black smoke, which indicates the burning of oil

Surrogate materials cannot be poured not only into the tank with gasoline, but also into the tank for chain lubrication. What will happen if you use mining in the tank to lubricate the chain, you can see in the video.

Using the instructions, you can independently prepare the correct fuel mixture, on which the chainsaw will work. With improper dilution of the fuel mixture, not only the tool life is reduced, but its performance is also reduced.
