What kind of oil for two-stroke engines of chainsaws

Husqvarna HP

It is a Swedish manufacturer that includes several well-known brands, including Partner (Partner), known for its semi-professional and professional gardening equipment. Husqvarna produces not only machinery, but also high-quality lubricants used in almost all brands of gasoline-powered tools.

The photo below shows a 2-stroke Husqvarna HP oil, which contains special additives that can compensate for the poor quality of fuel, which is not uncommon in our country. After all, the octane number of gasoline purchased at a gas station does not always correspond to the declared one.

This grease is green and contains a semi-synthetic base. It can be packed both in 10-liter containers and in 1-liter containers. The mixture is diluted in a standard ratio of 1:50 (20 g per 1 liter of gasoline). But when the engine has not yet been run in, or work is coming in the cold, the proportion can be increased to 1:40.

Choosing engine oil

An oil intended for a 2-stroke engine must meet the following requirements.

  • The lubricant should form a minimum of ash during combustion. Ideally, it should burn completely.
  • The lubricant must have good solubility in gasoline and a high degree of purification from various impurities that can cause clogging of very narrow channels of the carburetor.
  • The oil must have high anti-corrosion, anti-wear and lubricating properties.

There are certain standards for oils intended for 2-stroke engines: TC-W3 and 2T. TC-W3 standard grease is used for water cooled engines (outboard motors, jet skis). 2T oil is used as an additive in gasoline for 2-stroke air-cooled engines (lawn mowers, mopeds, chainsaws, etc.).

Oils can be green, red or blue in color. This is done so that their presence in gasoline can be easily determined.

When using poor-quality lubricant, the entire piston group of the engine can fail due to the formation of carbon deposits under the piston rings. As a result, they will not be able to compress, and scuffs will form on the cylinder walls. Also, improper lubrication of the bearings of the crank mechanism leads to overheating and, ultimately, to seizure. Important: it is forbidden to use diesel oil to prepare the fuel mixture, since it does not correspond to any of the above parameters.


The oil belongs to the highest category. It is created on a completely synthetic basis, has a green color and has high lubricating properties, and thanks to salt-free additives it does not create carbon deposits.

The oil was specially developed for the lubrication of engines operating for a long time at high loads and low ambient temperatures, up to 25 ° C. In addition, this lubricant is environmentally friendly. If spilled on the ground, it will decompose by 80% in 21 days. The grease is packaged in bottles of 100 ml and 1 l.


The grease has been specially developed for the engines of STIHL equipment. It has a mineral base, has high lubricating and cleaning properties and can be used at an ambient temperature of at least 10 ° C.

The bottle has a special dispenser that allows mixing the fuel mixture without using additional measuring containers.

The grease has a red color and can be stored for no more than 4 years in a closed container. The latter can have different capacities, both large and small (for one-time refueling). For example, there is a 20-gram container on sale, the contents of which are added to 1 liter of gasoline. This is a very convenient option for owners of chainsaws who use them occasionally. Important: a mixture of gasoline with this oil cannot be stored for more than 1 month, since during this time it will already lose its lubricating properties.

All about choosing your chainsaw oil

The resource of any chainsaw, no doubt, depends on the quality of its maintenance and operation. The most important requirement for this unit is the timely lubrication of all its moving parts. Chainsaw oil is available in different types, namely: motor and chain oil. The motor is poured into the internal combustion engine, and the chain is intended for the saw chain. Let’s figure out how to choose the right oil for a chainsaw.

STIHL Two-Stroke Chainsaw Engine Explained

How to determine the ratio of gasoline to oil

The fuel mixture used in 2-stroke engines is prepared from a certain amount of oil and gasoline. The latter must have an octane rating of at least 90 and be unleaded. AI-92 fuel is best suited for these purposes.

It is not recommended to use gasoline with an octane rating of 95, as it contains many different additives that harm two-stroke engines.

To prepare the mixture, you must use only engine oil from well-known manufacturers. The lubricant should be designed for high-speed engines with an air-cooled system. This component, intended for low-speed engines (moped, motorcycle, snowmobile), must not be used.

When preparing the mixture, it is required to strictly observe the proportion of gasoline and oil. As a rule, it is 1:50, that is, you need to take 100 ml of oil and dilute it in 5 liters of gasoline. This rule changes slightly if the engine or piston system is new and a break-in is required. In this case, the oil-to-gasoline ratio can be 1:40. For running-in, you will need 2-3 full refueling of the unit with a fuel mixture with this ratio. If you dilute the fuel mixture in a ratio of 1:30, then carbon deposits will inevitably form on the piston and inside the cylinder, which, as already mentioned, leads to a breakdown of the entire crank mechanism.

Below is a table that helps you quickly determine the gasoline-oil ratio if you need to prepare a large amount of fuel mixture.

How to Mix Fuel for a Husqvarna Two Stroke Engine Chainsaw

Choice of oil for chain lubrication

Remember to check the amount of oil in the oil tank after each refueling of the chainsaw with the fuel mixture. In a chainsaw, an oil pump is responsible for delivering lubricant to the tire on which the saw chain slides. Normally, filling both tanks. fuel and oil. should be done at the same time. Chain oil must be poured into a suitable tank up to the neck. Otherwise, it may run out before fuel, which will lead to overheating of the chain and bus.

Chainsaw chain oil must be designed specifically for this purpose. The use of other lubricants is ineffective and reduces the life of not only the saw, but also the tires of the machine. This is due to the fact that the chain oil contains adhesive additives, due to which the lubricant literally “sticks” to the chain. This property of the oil reduces its consumption, as a result of which the lubrication of the chainsaw bar and the saw chain is improved, and their service life increases.

Also an important parameter of chain lubrication is its density. If you are going to use a lubricant that is not intended for chainsaws, you may notice that oil leaks during operation or after stopping the unit. This fact suggests that the grease is too liquid. In addition, the liquid lubricant will quickly scatter in all directions and, accordingly, quickly run out.

When using a chainsaw in winter, you must use oil designed for low temperatures to lubricate the chain, otherwise the oil pump will fail. Therefore, the grease remaining in the tank must be replaced with a low-temperature one.

Leading manufacturers of gas powered tools such as STIHL, Husqvarna, Makita, Bosch and Oregon chainsaw accessories manufacturer recommend special highly adhesive oils, including biodegradable ones. But oils of well-known brands have only one drawback. for 1 liter and above. In addition, the grease in the reservoir can thicken over time and clog the channels. For this reason, it has to be drained, and this already increases the consumption. But despite this, we have to admit the fact that only the use of special lubricants can extend the service life of the chainsaw.

API Classification of Oil for 2-Stroke Engines

API stands for American Petroleum Institute. American Petroleum Institute. This organization develops standards for the oil and gas industry.

The Institute breaks down 2 tons of engine oil into 4 types:

  • TA is used in engines up to 50 cubic centimeters. Used in lawn mowers, trimmers, etc.
  • TB. for engines with a volume of 50 to 200 cubic centimeters. It is used in devices that create a large load: motorcycles, chainsaws.
  • TC. similar to TB, but used for high product requirements. The mixture has a high fuel to oil ratio. Used in motorcycles, snowmobiles, etc.
  • TD are designed for outboard boat engines. Compliant with NMMA TC-W standards.

The types presented cannot be substituted for each other, with the exception of TC. The third category can be used in motors rated for TA or TB.

STIHL HP Ultra is a premium lubricant. The product is synthetic, has a green color, contains additives that prevent the formation of carbon deposits. Has high lubricating properties.

Designed for engines operating in cold areas at temperatures up to 25 degrees Celsius. The grease is environmentally friendly with a half-life of two weeks. The substance is sold in containers of 0.1 and 1 liter.

An overview of popular types of oils for two-stroke engines of chainsaws, lawn mowers, etc. do in this

What gasoline to use

Chainsaws use the fuel recommended by the manufacturer in the documentation. Gasoline with an octane rating of 95 or higher is usually not used. Engines are designed for a certain load, exceeding which threatens to burn out the cylinder.

Read more about fuel in an interesting article. What gasoline to pour into a chainsaw.

Some models allow the use of gasoline with an octane rating of 95 and even 98, but it is safer and more profitable to use 92. And vice versa: lower values ​​are allowed, but not recommended for modern chainsaws. And the quality of the fuel is also important. Manufacturers artificially increase the octane number with various additives. While oils can help deal with this, better quality fuels will increase productivity.

Review of 2t engine oils designed for chainsaws

Specialty chainsaw oil is produced by many companies, although some simply disguise their products as well-known brands. High-quality lubricating fuel is manufactured by Husqvarna, STIHL, Makita, Champion, Oregon.

Husqvarna HP

Husqvarna is a Swedish company with several subsidiaries. The latter produce garden equipment and components for them under the general name. Husqvarna produces oils and greases for its products. Materials differ in quality and are used not only for branded tools.

Husqvarna HP 2-stroke oil contains additives that compensate for fuel deficiencies. This is especially important if the latter is of poor quality. This is due to gasoline, which has an artificially high octane number.

The oil is green. The basis of the products is semi-synthetics. Sold in liter and ten liter containers. To mix oil with gasoline, a ratio of 1 to 50 is required. If the product is used in the cold season or the saw engine is not run-in, it is recommended to slightly increase the proportion.

Why you need to use 2-stroke oil

Two-stroke oil must burn completely, leaving no thermal reaction products. smoke and carbon deposits. It must also mix well with fuel, which is unacceptable in four-stroke engines.

The four-stroke oil, on the other hand, is used in forced lubrication and is designed for long-term use. The product contains many additives that improve its properties. The use of 4t oil in 2t engines will lead to the appearance of deposits that interfere with the operation of the device.

Two-Stroke Chainsaw Engine Oil

Two-stroke oil for chainsaw engines must dissolve in gasoline and burn completely during operation. Also important are fluidity, resistance to temperature changes and wear, anti-corrosion effect. Which oil meets these requirements? Within the framework of the article, we will figure out why it is impossible to use four-stroke oil, which oil manufacturers are recommended to use, classification of oils 2t.

How to choose the right saw oil?

After buying a chainsaw, of course, questions arise about the operation of the tool. Proper care of garden equipment allows you to increase the duration of its operation without breakdowns. The main factors in the performance of your chainsaw are the use of the correct fuel and lubricant. over, the greatest difficulties for owners of chainsaws are caused by oils for saws. We will tell you how to choose oil for two-stroke engines of chainsaws, since it is this oil that is used in gardening equipment.

Feature of oils for two-stroke engines

Any chainsaw has a two-stroke carburetor engine and is equipped with two tanks. one for gasoline, the other for oil. The difference that oil for two-stroke engines of chainsaws has. it is the need to constantly add saw oil directly to gasoline. This is important as otherwise the tool may simply break.

To determine which chainsaw oil to use, you need to know the following. For domestic models, conventional motorcycle oils are required, which are added to the fuel mixture in a ratio of 1/25. Chainsaws of foreign manufacturers are more demanding on the quality of the lubricant, therefore, it is better for them to use branded oils with m in a mixture of 1/40. In principle, the owner of the tool decides which chainsaw oil to use. The use of domestic oils in foreign devices is allowed, however, such actions are fraught with a decrease in the motor resource of the tool.

We select oil for the electric saw

Questions about what kind of oil to use for the chainsaw are not straightforward. Experienced owners use motor oil for the saw chain, and in its absence, transmission oil. The advice of experts in this area boils down to the fact that the saw unit can be lubricated with ordinary Lada oil, but there are also special recommendations, for example, Husqvarna chainsaw oil should be engine oil, and STIHL chainsaw oil should be transmission oil.

Learning to distinguish oil by color

Two-stroke chainsaw oils are colored blue, red or green. When choosing an oil, it must be borne in mind that in most cases the manufacturer of the saw indicates the correct qualitative and quantitative composition of the oil and the fuel mixture. So, choosing oil for a Husqvarna chainsaw will not be difficult also because there are oils specially developed for a specific model. There is also a special oil for STIHL chainsaw, which is suitable for lubricating chains and adding to the tank.

In any case, chainsaw lubrication does not require special and expensive oils, although such products are capable of guaranteeing longer work without breakdowns.

Review of famous brands of oil for chainsaw engine

So, pouring anything into the chainsaw is not worth it. For those who have not decided on the choice, there will always be a time-tested and familiar assortment from different manufacturers.

Features of “chain” oil

If the engine arsenal should have properties such as purity and low ash content, then the chain oil should have completely different basic characteristics. It does not burn, so it is not required to be free of carbon deposits after use.

The design of the saw headset includes a bar with a drive and driven sprocket and a chain. Lubrication of the blade facilitates its movement along the tire channel, the passage of the driving links along the sprockets, reducing the wear of the rubbing pairs. Since the oil is applied to the surface of the chain in special holes or grooves, it must adhere well to the canvas, since when the stars rotate, the centrifugal force will cause it to fly apart.

At maximum revs, such expansion is inevitable. There is even an experiment to check the lubrication on the chain:

Apply full throttle while holding the tire over a fresh cut. Drops of oil that appear will indicate that there is sufficient lubrication.

Based on this, two important characteristics of “chain” oils can be outlined:

  • Good adhesion. This means that the oil must adhere as tightly as possible in the grooves and holes in the chain. At medium revs, it does not even come off the surface. Such indicators are associated with viscosity. it is quite high for lubricants. At the same time, excessive thickness also harms the chain. the oil does not have time to envelop the chain in the required amount.
  • High environmental friendliness. Chain oil enters nature almost unchanged, like from a bottle: it drips onto the ground, remains on wood, bushes, grass. Once in the snow, it flows into a body of water in the spring. Its influence may seem insignificant, but thousands of chainsaws are in operation all over the world. Large companies are very concerned about environmental issues. Therefore, they try to make their oils environmentally friendly. Many are plant-based and disintegrate in a few days. Therefore, high-quality products have a limited shelf life.

Husqvarna HP 2

The Swedish manufacturer does not spoil us with the same variety as its German competitor. The branded oil available for purchase is a laconic dark package with a volume of 1 liter. Occasionally you can also find cans of 5 liters. The color is green, the base is mineral, but with additives, so it would be logical to attribute this product to semisynthetics. The company is significantly silent about secret additives, which not only minimize the amount of carbon deposits, but also compensate for the poor quality of the fuel. The Swedes position their product as universal, suitable for both the household segment and professional equipment.


The Swedes did not stay away from the “chain” lubricants. This segment offers two options:

A universal solution, both for amateurs who value their efforts and tools, and among professionals who need maximum speed and durability. Biodegradation is mandatory.

A more budget-friendly solution for the amateur sector. Positioned as reduced flow oil. In practice, it almost does not differ from competitors in terms of the speed of emptying the tank.


This is already pure synthetics. In the STIHL line, it is the most advanced and expensive. Also green in color, only slightly lighter than Super. Suitable for motors of powerful professional tools. It differs not only in maximum purity, which benefits the engine and nature, but also in excellent frost resistance. Does not change its density and solubility in harsh conditions where logging is carried out. Filled in containers of 0.1, 1 and 5 liters.

German manufacturer is unlikely to clash with Greta Thunberg over its premium oil: HP Ultra disintegrates outdoors in 21 days.


Belongs to the category of semi-synthetics, surpasses normal HP in all respects, including the price. Has a dark green color. Differs in low ash content. No carbon deposits on the piston and cylinder walls, and less smoky exhaust.

Engine oil

Without exception, all chainsaws, like their fellow mowers and cultivators, are equipped with two-stroke engines. When small in size, they develop a high power density. Due to the completion of the working cycle in two strokes, the speed of such engines also exceeds the usual automobile ones. On the other hand, there is a strong load on units and parts, air cooling, which also requires a safety margin in the design. Reducing the wear of elements is possible only by using high-quality lubricants.

A feature of two-stroke motors is the absence of an oil pan and a pump that would deliver liquid lubricant to all rubbing and interacting parts. The advantage of this scheme is its structural simplicity, fewer units in the engine. On the other hand, the question arises of how to deliver the lubricant to critical places, of which the most demanding is the cylinder and piston.

The solution was to add oil to the fuel. Gasoline is not poured into the saw tank in pure form, but with the addition of lubricant in a certain proportion. Before entering the combustion chamber, this mixture washes the necessary components, and then leaves the exhaust manifold in the form of exhaust gases.
