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.

Those who constantly use a chainsaw, as no one else understands that how long and in high quality it will serve depends on the correct ratio of oil and gasoline when refueling the mechanism. Before using a power tool, you should pay attention to its brand and features, since each manufacturer recommends a different ratio of fuel and lubricants.

About how to refuel petrol, the correct ratio of oil and gasoline and the preparation of various working mixtures will be discussed in this article.

### Features and characteristics of various chainsaws

Regardless of the brand, each chainsaw has a basis through which it works safely. Without a two-stroke carburetor engine and two tanks, it is impossible to imagine any mechanism.

• Each of their parts plays a crucial role in the operation of a power tool and complements the rest of the elements. In one of the tanks should be a fuel mixture consisting of gasoline and engine oil.
• Typically, the proportions in the ratio between gasoline are determined by the manufacturer, it is extremely important to comply with them.
• As a rule, the consumption of gasoline and oil is enough for the same period, but at the same time gasoline is poured more than one and a half, or two times.

The constant addition of oil to the fuel tank is almost certainly an event that allows the saw to work for a long time and without interruption. No one who uses this mechanism wants to constantly engage in repair work, but if the fuel is not diluted with oil, the saw engine may malfunction and it will fail.

Of course, only personal experience can suggest the correct ratio of fuels and lubricants. However, one should never neglect the recommendations from the manufacturer, as independent experiments can lead to the breakdown of expensive mechanisms. It is also worth noting that budget mixes are suitable for domestic saws than for foreign counterparts, so prudent owners try in this case to save the budget and buy cheaper supplies for devices.

### Which gasoline is suitable for a chainsaw

Older models of Russian chainsaws work normally on A-76 gasoline, but for chainsaws manufactured abroad, it is better not to use this fuel, but to fill the tank with better gasoline, such as A.92. But, here the question may arise about the quality of the very gasoline that is purchased at gas stations in the country, it often doesn’t correspond to the declared composition. In order not to risk in vain, some owners of imported chainsaws buy 95 gasoline.

They are also not advised to use fuel that has stood unnecessarily for a long period. The fact is that gasoline is capable of losing its main characteristics over time. For example, the octane number in gasoline is of great importance, with a decrease in which, during operation of the saw, a decrease in engine power may occur.

A chainsaw may become unworkable due to the filling of poor quality fuel. Sometimes such an error is very expensive for the owner, since repairing a failed mechanism costs much more than fresh and expensive gasoline.

### How to choose a little for chainsaws

• The most common oil for use in chainsaws available to most Russians is API.Tv motor oil.
• Another brand is also used. Api-TS, but here the manufacturer’s permission is required to use the material, as well as its amount when added to gasoline.
• There is another option, for saws with a small load, API-TC oil may be applicable here.
• All of these brands are classified by the American Petroleum Institute, but there is another no less popular series of oils that are produced by the Japanese. They also classify lubricants into power classes. For the operation of chainsaws, fuel and lubricants of the JASO-FB and JASO FD brands are recommended.

Note! Do not use oils created for four-stroke engines in chainsaws with two-stroke engines.

In the second case, the lubricant must completely burn out. This effect can only be achieved through the use of synthetic oil, it gives a minimum of smoke and almost does not leave any residues. It is important to read the instructions for using and mixing consumables for a particular brand of chainsaw.

### How to make a mixture of chainsaws from oil and gasoline

After you have studied the full information from the manufacturer, which is necessarily present in the accompanying documents, you can proceed directly to pouring materials into the tank.

For chainsaws with a capacity of less than one and a half kilowatts, oil is poured 50 times less than gasoline. But there are exceptions, for example, in Chinese chainsaws, these proportions come down to 1X25, but for the manufacturer Partner again, changes up to 1X40 consumption. For the Husqvarna and Stihl brands, the proportions of 25 ml of oil per 1 liter of gasoline are applicable.

If you do not comply with the recommended dosage of combustible materials, a lot of problems can arise:

• Engine parts, between which friction occurs during the operation of the saw, will more likely wear out, which means the mechanism itself will last less,
• Bearings will fail faster;
• The resource of the mechanism will be significantly reduced;
• The device will become less functional.

Preparation of the mixture should be carried out immediately before starting work. But after its completion, the unburned remains of combustible material and oil are necessarily drained. It is strictly forbidden to store them in a gas tank, even for several days. This is due to additives in the oil, it will begin to break down directly in the tank, because caring owners drain the rest of the mixture and then start the chainsaw at idle.

The best option for mixing the mixture is a canister with various openings for gasoline and oil. The correct mixture is obtained when mixing consumables from the tilt of the canister. Plastic or glass containers can be used to prepare the working fluid, but in this case there is a risk that fuels and lubricants will ignite. But plastic containers are also not convenient, as they can easily bend and pour into your hands or mechanism.

Dilution of gasoline is carried out only in dry and clean containers, any residues and liquid particles will lead to a violation of proportions when mixed. Therefore, care should be taken to check the tank for all kinds of dirt or residues.

Take all possible precautions when mixing combustible supplies. Rubber gloves should be put on your hands, manipulations should be done carefully, without spilling a drop of gasoline on the surface of the earth or floor. If the fluid accidentally spills out, it must be wiped with a cloth and disposed of.

### Oil producers

• The most interesting proposals regarding not only oils but also chainsaws are available from Stihl. Our men appreciated the quality of engines and consumables, so they are incredibly popular. If you have such a mechanism in your household, you should not spend money on cheap materials.
• Another world brand for the production of chainsaws stands out. Husqvarna, which is famous for manufacturing high-quality motor materials for two-stroke engines. However, when using them, excessive smoke is noted, and this is with incomplete engine power.
• Ravenol is also a well-known brand that you can buy without fear. The main thing to be afraid of is the fakes that flooded today’s markets around the world.

The fact that it is forbidden to pour “clean” gasoline into chainsaws is warned by buyers’ sellers at the time of purchase of the tool. Many buyers learn about this for the first time, wondering why it is necessary to dilute gasoline with oil. If this rule is neglected, then the consequences for the instrument can be simply catastrophic. In most cases, even engine overhaul will no longer be able to help. In the material, we find out what proportions of gasoline and oil should be for refueling the chainsaw, and also what may lead to non-compliance with this rule.

At the heart of any chainsaw is a two-stroke internal combustion engine. This is one of the simplest mechanisms, consisting of one cylinder and without a separate lubrication system. The technology is such that the lubricant must enter the cylinder with the fuel mixture, settle there, and lubricate the cylinder walls, piston rings, etc. The simplicity of the design of the tool has many advantages, among which the main one is the ability to repair the engine and its components independently.

Diluting gasoline, which is poured into the chainsaw, is required in order to extend the life of the tool. Diluting the fuel with chainsaw oil is mandatory, and if for some reason you forgot to do this, then the use of the tool is strictly contraindicated.

It’s important to know! In chainsaws there is no special tank for pouring oil, which would be spent for lubricating the rubbing parts of the engine, as in cars. This is due to the simplest design of a two-stroke motor. The present oil tank in the chainsaws is designed to lubricate the chain and tire during the operation of the tool.

### Proportions of oil and gasoline for chainsaws

How much oil to add to gasoline for a chainsaw is indicated primarily in the instructions for use of the tool. If you forget what the proportion of oil and gasoline should be, then you can always open the instructions and update your knowledge. If the instruction is lost, then this material will help you. To begin with, it is worth noting that there are several options for mixing oil materials with fuel. Choosing any, it is worth noting that the main criterion for each is the correct measurement of the components. Only exact observance of the proportion of oil and gasoline will achieve the fuel mixture of the necessary technical qualities.

One of the most common proportions is 1:50. This means that 1 liter of gasoline must be diluted with 20 ml of oil. This recipe for the preparation of the mixture is relevant for tools whose power exceeds 1.5 kW. This option is one of the most popular, so if you forget the exact proportions for your instrument, you can always focus on the first option.

The second option provides for a proportion of 1:25. To mix 1 liter of gasoline with 10 ml of oil is recommended by Chinese manufacturers for their tools. For tools whose power does not exceed 1.5 kW, it is recommended to pour oil in an amount of 25 ml per 1 liter of gasoline. Each manufacturer’s chainsaw has its own limitations, and recommendations for the preparation of the fuel mixture, which are recommended to be followed. The two main options that are universal are listed above.

It’s important to know! The excess amount of the oil mixture in the fuel is also negative, as this will lead to a reduction in engine life due to increased shock loads on the cylinder and piston, and will also lead to the formation of soot.

Not everyone knows what kind of gasoline to pour into a chainsaw. This is also indicated in the technical documentation for the chainsaw. In modern saw models, it is recommended to pour fuel of a brand not lower than AI-90, that is, AI-92 or AI-95. And it doesn’t matter who the tool manufacturer is, China or Europe. Professionals recommend the use of AI-92 gasoline, since the 95th is in most cases made from 92 by adding additives. If you know for sure that it is really pure 95, then it is better to use it.

Many craftsmen continue to pour gasoline of grades lower than AI-90 into modern chainsaw models, as this was allowed to be done for obsolete models of tools: Friendship, Taiga, and others. This is not recommended!

Which oil to use to lubricate the chainsaw chains depends on the model of tool. Stihl brand saws and the like produce special lubricants that are intended only for use in such tools. Recommended oils can also be found in the technical documentation. When choosing a lubricant, attention must be paid to ensure that it is intended for two-stroke engines. Oils for mixing with gasoline and for chain lubrication differ in composition, quality and purpose. You can not mix them, as this will accelerate the failure of the tool. Recommended brands of oils for two-stroke engines:

### Saw refueling algorithm

A mixture of gasoline and oil is best prepared in a 2.5-liter plastic bottle if you often need to refuel the tool. If it is necessary to prepare fuel for only a few refueling, it is better to use a smaller tank. It is recommended that you acquire measuring tanks, this will allow you to observe the exact proportions of both liquids. Most oil manufacturers offer such measuring devices.

Initially, fuel is poured into the tank, and then oil is added. It is important to consider that there should be enough space in the tank to thoroughly mix the fuel mixture.

It’s important to know! It is strictly contraindicated to prepare the fuel mixture directly in the tank of the instrument.

After preparation, it is recommended to store this mixture no more than 2 weeks. At each filling, it is recommended to shake the mixture thoroughly. If you are not sure that all fuel will be used up, it is better not to cook it in large quantities.

### Risks of using fuel and oil substitutes

To avoid premature failure of the chainsaw, it is recommended to refuel the tool with exclusively high-quality and branded consumables. Finding such materials is not difficult, since they are usually sold at branded points of sale. The use of low-quality gasoline can cause engine failure, so it is recommended to buy fuel at gas stations where high fuel quality is guaranteed.

It is strictly contraindicated to mix gasoline with motor oil for cars, since it is not at all intended for such purposes. Compliance with the number of proportions, as well as the use of quality materials will extend the life of your tool for many years.
