Chainsaw oil Husqvarna which to use

Stihl HP Ultra

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.

Stihl HP

The grease was 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.

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.

Overview of manufacturers of oils for internal combustion engines

Among the manufacturers producing the best two-stroke oils, we can confidently name 2 leaders. these are Husqvarna (Husvarna) and Stihl (Stihl). The companies produce not only conventional mineral oils, but also synthetic lubricants designed for 2-stroke engines operating in severe conditions.

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.).

MOTUL Outboard Tech 2T Oil

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.

Fuel mixture preparation rules

It is necessary to dilute gasoline with oil in containers that are resistant to the effects of petroleum products (plastic or metal canisters). It is not recommended to use plastic bottles from under water, juice or milk for these purposes, as food grade plastic decomposes under the influence of gasoline. As a result of this process, the fuel mixture will change its properties, and it is difficult to predict what effect it will have on the engine.

The combustible mixture for the chainsaw is easy to prepare.

  • Take the required amount of lubricant and pour it into the prepared container. Do not pour all the prepared gasoline into a container with oil, half of the required amount will be enough.
  • Slightly shaking the container, wait until the lubricant is completely dissolved in gasoline.
  • Now you can fill in the remaining gasoline, mixing it well with the mixture in the container. This completes the preparation of the fuel mixture for the chainsaw.

Before each refueling of the chainsaw, the combustible mixture must be shaken. Also, do not forget to tighten the fuel tank cap well, otherwise this will lead to a lean mixture and engine failure.

It is better to use the ready-made fuel mixture immediately. Therefore, it must be prepared in such an amount that it is enough for the expected volume of work. If, nevertheless, the mixture remains, then it is impossible to store it for more than 1-1.5 months. During this time, it will lose a significant part of its lubricating properties.

What parts of a chainsaw need oil

If you look closely at a working chainsaw, you will immediately notice its main moving part. the saw chain, which slides along the tire during sawing. Since the law of friction still exists, both parts gradually wear out. To slow down this process, it is customary to use chain oil specially formulated to lubricate saw chains.

Chainsaws can be equipped with both four-stroke and two-stroke engines. For 4-stroke units, the crank-connecting rod group is lubricated with oil in the engine crankcase. Two-stroke engines differ slightly in their design and operating principle. Gasoline for this type of drive goes directly into the space under the piston, where the crank mechanism is located, which has several bearings and bushings that need lubrication. Therefore, oil for two-stroke engines of chainsaws is added to gasoline so that it, falling on the rubbing parts of this block, lubricates them.

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, use only engine oil from reputable 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.

What oil to use for a chainsaw engine

To lubricate the internal parts of a chainsaw engine, special oils must be used that differ from lubrication for four-stroke engines in several ways.

  • The first is the quality of cleaning. Chainsaw engine oil should be as cleaned as possible from various impurities. This is due to the fact that the channels in the carburetor of the chainsaw are too small and if the fuel mixture has any impurities, they will clog up, and accordingly the engine will stop working.
  • Second, it is low smoke when burning. As you know, saw oil must be mixed with gasoline, which subsequently burns out in the engine cylinder, and, accordingly, the lubricant burns with it. If a large amount of smoke is emitted from the burning mixture, this will negatively affect the exhaust system and, alternatively, the health of the operator.
  • Third, chainsaw lubricant should burn with minimal carbon build-up. Low-quality oils, when burning, form a large amount of carbon deposits, which coke the piston and the exhaust system.

The consequences of using low-quality oil can be very sad, to the point that it will be necessary to replace the piston group of the chainsaw. Coking of the exhaust system entails a decrease in engine power, since the throughput of the muffler and the exhaust window of the cylinder decreases, up to their complete clogging. Carbon deposits under the piston rings will not allow them to shrink, which will lead to the formation of scoring on the cylinder walls and engine seizure.

Important: it is strictly forbidden to use diesel oil for a chainsaw, since it is not suitable for all of the above parameters.

Using special lubricants for two-stroke engines is not only beneficial for the engine, but also convenient, since manufacturers add dyes to them, thanks to which it is possible to determine whether gasoline is diluted or not, which is impossible in the case of conventional engine oils. Four-stroke engine oil mixed with gasoline is colorless.

The mixing ratio for a two-stroke engine is indicated on the packaging. Manufacturers recommend adhering to the dosage, since the use of the wrong mixture of oil and gasoline also affects the life of the engine, and it is harmful to both increase and decrease the proportion.

Tip: a guarantee of the performance of the chainsaw engine is the use of high-quality oil in the correct proportion.


STIHL HP Mineral Grease has been specially developed by STIHL engineers for use in their tools. That is why owners of chainsaws and Stihl lawn mowers are recommended to use this type of oil.

Its color is red, shelf life in a closed container is no more than four years. It is packed in several types of containers, so you can choose the most convenient packaging for yourself. Not so long ago, a convenient container of 20 grams appeared, which is diluted by one liter of gasoline. For those who rarely use a chainsaw, this is the best option. Can be thinned and consumed immediately.

Important: it is not recommended to store the finished fuel mixture for more than one month, since it gradually oxidizes and the lubricating properties are lost.

STIHL HP fully complies with high European standards.

Main brands of chainsaw motor oils

Stihl and Husqvarna are leaders in the production of quality lubricants for chainsaws and lawn mowers. Their range includes both conventional mineral lubricants for two-stroke engines and synthetic heavy-duty oils. Let’s consider the assortment in more detail.

Husqvarna HP 2-stroke

Husqvarna HP, like its STIHL HP counterpart, is also specially designed for 2-stroke engines.

According to the manufacturer, this type of oil has additives that compensate for the low quality of the fuel, which is important for our country. The declared octane number of gasoline at filling stations rarely corresponds to the real.

Husqvarna HP. semi-synthetic, green. It is packed in a liter or ten-liter container. The proportion of the mixture is 1: 50, i.e. 20 grams per liter. During the running-in period of the saw engine or when working in cold weather, it is allowed to increase the proportion to 1:40, which will give the engine more protection and increase its service life.

Today, there are a large number of two-stroke engine lubricants on the market from different manufacturers. For this reason, it is rather difficult to answer the question of which chainsaw oil is better. In our opinion, you should trust reliable companies, which are Stihl, Husqvarna, Oregon, Champion. It is their oils that will allow you to maximally protect the engine of your tool and extend its resource.

Unscrupulous manufacturers often disguise their products under well-known brands (Husqvarna, Stihl, etc.). Such oils are of poor quality and can damage the engine. In order not to be deceived, it is necessary to purchase lubricants from official representatives who have the necessary certificates for the products. How to distinguish a fake from an original can be found in

HP Ultra

Another oil from Stihl. Has a synthetic base, due to which it has improved combustion characteristics, cleanliness and engine protection.

Recommended by the manufacturer for long-term use in harsh conditions. Ideal for low temperature applications. HP Ultra is environmentally friendly as spilled oil decomposes 80% in just 21 days.

It is packed in two types of containers, 100 ml and liter bottles. The proportion of the finished fuel mixture is 1:50, which means that a 100 millimeter bottle is enough to prepare 5 liters of the mixture. Green colour. Shelf life 4 years.

The cost of this oil is significantly higher than the cost of STIHL HP, therefore it is not profitable to use it constantly.

It is worth noting that Stihl oils, before they go on sale, go through the company’s laboratory, where they are tested for compliance with all requirements.

When developing oils, great attention is paid to fuel combustion, starting characteristics during cold start, biodegradability, viscosity change at different temperatures (information from the official website of the company).

How lubricant quality affects engine life

Now let’s talk about how specifically the quality of the oil affects the operation of the engine and its resource, since many do not understand this.

The principle of operation of a two-stroke engine implies that the lubrication of its internal parts is due to the oil in the gasoline. It lubricates the crankshaft and connecting rod bearings. Also, the oil envelops the cylinder walls and reduces the friction of the piston rings.

The engine of the chainsaw is highly revving, some models can develop up to 15,000 rpm, which puts a tremendous load on the bearings and other engine parts. Insufficient or poor quality lubricant will cause the bearings and piston to run virtually dry, resulting in increased temperatures. Elevated bearing temperatures can cause bearing seizure.

Heating the piston to the limit causes it to melt, particles of aluminum from the piston are transferred to the surface of the cylinder and, cooling slightly, become solid. Rings, passing the area with aluminum build-up, get damaged or wedge.

Another danger of poor-quality lubrication is carbon deposits. Carbon deposits can form under the piston rings, making it difficult or completely stopping their proper operation, and in the exhaust port. It is not uncommon for carbon deposits to completely seal the exhaust window and muffler. Below is a video about the consequences of using low-quality oil.

Choosing the right chainsaw oil

Almost all modern chainsaws and lawn mowers are equipped with two-stroke engines. Their lubrication is due to the oil that is added to gasoline, there is no oil sump and pump in them.

In order to extend the life of the engine, it is necessary to use special lubricants, which will be discussed in this article.

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 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.

How to choose the right saw oils?

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.

chainsaw, husqvarna, which

We select oil for the saw

Questions about which saw chain oil to use are ambiguous. Experienced owners use engine 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 oil for “Zhiguli”, but there are also special recommendations, for example, oil for the husqvarna chainsaw must be motor oil, and oil for the stihl chainsaw must be transmission oil.

Learning to distinguish oil by color

Two-stroke chainsaw oils are colored blue, red or green. When choosing an oil, it should be borne in mind that in most cases the saw manufacturer indicates the correct qualitative and quantitative composition of the oil and fuel mixture. So, choosing oil for husqvarna chainsaw is not difficult also because there are oils specially designed for a specific model. There is also a special oil for the 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 able to guarantee a longer operation without breakdowns.

Is it possible to pour car oil into a chainsaw?

Yes, you can. One-time for simple tasks without heavy workload. For example, imagine the following situation.

Initially, no work was planned using a chainsaw. Therefore, the specialized lubricant 2T was not purchased in advance.

But upon arrival at the dacha, it was discovered that, for example, a tree had fallen on the fence. And it urgently needs to be cut and removed. In this case, you can use one-time motor lubricants.

Basic rules of application

Two-stroke chainsaw oil is most often created on a mineral base. Less commonly, it is synthetics or semi-synthetics. Oil for 2-stroke chainsaw engines is mixed with fuel according to technology even before filling into the tank.

Pouring grease directly into the tank is also practiced, but it is not the most reliable method. Especially if the tank was completely empty. In this case, the plug is likely to partially enter the system without lubrication. And the engine will run dry for a while.

If, when using lubricant, it is found that a wet oil deposit remains on the spark plug, and dirty working off drips from the exhaust pipe, these are clear signs of incomplete combustion or the use of poor-quality lubricant. It is necessary to reconsider the choice of engine oil for a chainsaw and the proportion of its use.

Stihl chainsaw oil

Stihl chainsaw engine oil is now generally recognized as the best option for this technique. And this is logical. No one knows better than the saw manufacturer what properties a lubricant should have to create the most favorable operating conditions.

There are several types of oil available from Stihl for gasoline saws. In Russia, two options are common.

Other lubricants

There are two more well-known manufacturers of chainsaws, whose products occupy a significant market share in the Russian Federation. These are Makita and Patriot. These manufacturers’ chainsaw engine oil is also available under their own brands.

What oil for Makita chainsaw to use? Ideally, of course, original from the same manufacturer. Lubricants produced under the Makita brand have a balanced set of qualities and a relatively low price among similar branded products.

Which Patriot Chainsaw Oil to Use? There are also branded lubricants here. It is best to apply them. over, these oils are produced in several versions.

The branded product line also includes chain lubricants. Patriot brand chainsaw lubricants have proven themselves well. And today they are often used as alternatives in other techniques.

Lukoil 2-stroke oil stands out from domestic products. At a low cost, this product has truly impressive properties.

After its use, in most cases carbon deposits do not form in the combustion chamber. Lukoil oils mix well and have good lubricating and protective properties.

It is also worth noting such an immortal option as ordinary M8 engine oil. Despite the large abundance of specialized lubricants, many owners of chainsaws use it the old fashioned way.

This option is permissible in the short term and only for light operating modes. But you need to be prepared for the appearance of abundant deposits if you use motor lubricants on an ongoing basis.

In the industrial field, they cannot be used: they will greatly affect the saw resource. It is safer to use specialized lubricants.

Choose synthetic, semi-synthetic or mineral oil?

Here again, everything depends on the type of saw and its constructive purpose, as well as the nature of the work. If the saw works in industry for cutting thick logs or processing hardwood, and not at home (for household needs), in the long term it may well be more profitable to use synthetics or semi-synthetics.

Rules for the selection of oil for chainsaws and lawn mowers. video

If the chainsaw is in household use, then ordinary mineral water is quite suitable.

How to mix gasoline with oil?

The exact technology of the mixing procedure itself (not proportion), which should be strictly adhered to, does not exist. Usually an empty container with a measuring scale is taken, gasoline is poured into it.

For example, 1 liter. Then the lubricant is added. To take the required portion of the lubricant, a syringe or a measuring cup with a graduation of 1 ml is used. The mixture is thoroughly mixed and poured into the saw.

It is not recommended to use such a method as diluting oil and gasoline immediately in the fuel tank of the scythe. Especially if the tank was completely dry before. Immediately after filling into the tank, gasoline will enter the fuel line without oil.

That is, after the oil is added, the saw will still run without lubrication for some time after starting. And this one is just at the moment of starting and warming up, when the engine needs protection the most.

Mineral Stihl HP

Has a red tint. Not biodegradable. Using this oil is highly discouraged to use the chainsaw indoors.

The grease mixes well with gasoline. However, during prolonged downtime, it is recommended to completely drain the fuel from the tank, since in the diluted state the properties of the oil gradually decrease.

Even with long-term use of the saw with Stihl mineral lubricant, carbon deposits on the piston skirt, cylinder and spark plug are minimal. This lubricant is relatively cheap and most popular in Russia.

How to dilute oil for “Stihl”?

The standard ratio is indicated as 50: 1. That is, 1 share of lubricant is poured per 50 shares of gasoline. If we proceed from the data on how much oil to pour into the Stihl 180 chainsaw (200 grams), then 1 full tank will need only 4 grams.

How to prepare a mixture for chainsaws. video

That is, for 1 liter of gasoline, you will need to add 20 grams of oil. Some Stihl grease cans have a built-in dispenser for easy dilution.

How to replace the original expensive oil and is it worth?

In situations where it is not possible to use the original ones, they can be replaced with oil for car engines. Cheap automobile oils such as autol or diesel lubrication options, due to low adhesion properties, are unsuitable for long-term use.

Some owners, despite the recommendations, still use analogs, preferring to change the tire and chain more often, but here everyone decides for himself. Such oil cannot have any negative effects on the chainsaw lubrication system, which means the difference is only in the quality of the tire protection against chain friction.

Chainsaw sprocket lubricant

To increase the service life and reduce friction on the drive sprocket, the manufacturer equips this mechanism with a needle bearing, which must be lubricated periodically. Stihl multipurpose grease can be used for lubrication.

If you do not want to overpay, it is better to use an inexpensive, but no less high-quality option, Litol or Litol 24 grease. Due to its viscosity, Litol will easily replace the original.

It is possible to lubricate the sprocket of the chainsaw tire with the same lubricants as the leading one, using a special filler for this. This allows the lubricant to be pressed in, through the technological holes in the tire, to the sprocket bearing.

Expert oil comparison

As a result of comparative tests, 3 winners were determined:

  • Caliber. cheap, good adhesion, biodegradability.
  • Oregon. average price, good adhesion, time-tested brand.
  • Stihl. expensive, time-tested brand, affordable price, a lot of fake.

Here everyone chooses what is closer to their liking and. the possibility of biodegradability or the price. Editor’s Choice. Oregon is a middle ground between quality and price.

What oil to use to lubricate the chainsaw chain

The answer to this question is quite simple, for this you need to open the instructions for any saw and it will indicate that you need to fill in oil that has a good adhesion effect.

Adhesion is a measure of the adhesion of a material, in this case oil, to the metal surface of the bar and chain.

What is it for? The fact is that the chain moves along the tire at a high speed, and if oil is used as a lubricant, which has low adhesion, then most of it, by inertia, flies off the end of the tire and lubrication of its lower part does not occur. This phenomenon can be observed with a small experiment.

Start the chainsaw, point the end of the tire towards a bright surface and add maximum gas. As a result, oil stains will appear on it, which are proof of the theory. Also, we definitely recommend reading an interesting article on how to start a chainsaw.

Other manufacturers

Less common manufacturers of adhesive oils specifically designed for lubricating saw chains, but popular with chainsaw owners, are:

  • Carver;
  • Adhesive CHAMPION, sold in containers up to 10 liters, which is convenient for use in forestry;
  • Makita Biotop;
  • Caliber;
  • Fubag;
  • Oregon;
  • Makita.


The company offers its customers Husqvarna Bio Advanced oil for use in normal and extreme conditions. The oil is produced from plant components and is environmentally friendly, it is supplied in one liter and five liter containers.

As an economical solution, the company has Vegoil oil, according to the manufacturer, its consumption is reduced by 40% compared to others. Supplied in a liter container.

The company also produces bearing grease, which it recommends for lubricating the bearings of the drive sprocket and the sprocket on the saw bar.

We recommend reading an interesting article about all Husqvarna oils.

You can also get acquainted with some oils for chains by watching the video below, in it a seller of a large network of tools, comments on the use of adhesive oils from various manufacturers.

Manufacturers of adhesive oils

Almost all manufacturers of chainsaws are engaged in the production of consumables for them, explaining that these products are most suitable for use in conjunction with their saws. There is no information about how true this is, but based on the experience of operating and repairing chainsaws, it can be noted that there are no significant differences in the service life of parts or at least visible wear.

But the fact is the fact, the manufacturers recommend and cannot be hidden. So, back to the manufacturers, and start with the popular Stihl brand.

Chainsaw chain oil. which one to use

You are a recent owner of a chainsaw, and you still do not know which chain oil is best to use. Lack of this knowledge can have a detrimental effect on the tool, since the type and quality of the lubricant determines how long the tire and the tool chain will maintain their performance.

After reading this article, you will fill the knowledge gap, because we will consider the use of oils, of various manufacturers and brands, to reduce friction between the parts of the saw headset. And also we will figure out what additional lubricants are used to service the chainsaw in order to maximize its service life.

Stihl HP Ultra

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.

Features of lubricants for chainsaws

Most oils are flammable because they contain hydrocarbons. Mineral oil is actually a product of oil distillation. However, in four-stroke engines, special mechanisms are provided to prevent the penetration of lubricant into the cylinders. The reverse process, when the engine “eats oil”, leads to increased smoke generation and is considered a malfunction.

In a two-stroke engine, the opposite is true. oil must enter the combustion chamber and turn into smoke from the exhaust system. This led to a number of rather stringent requirements for good chainsaw oil:

  • Maximum complete combustion. The less smoke and soot is produced when burning oil, the cleaner the channels through which the exhaust gases pass. A very important requirement for manufacturers of oil for two-stroke engines is its environmental friendliness. A large amount of smoke and soot from the exhaust pipe can not only harm nature. It is inhaled to one degree or another by the operator using the tool. Therefore, oil that burns completely, with a minimum amount of smoke, is preferable for modern models of chainsaws.
  • Purity and absence of impurities. The chainsaw carburetor is miniature in size. The channels through which the fuel mixture moves are so narrow that various foreign inclusions can partially block or even clog them.
  • Combustion of the oil-gasoline mixture should take place with minimal formation of carbon deposits. Otherwise, during regular operation, the working cylinder cokes: the resulting carbon deposits cover the walls of the combustion chamber and the piston, leading to wear of the cylinder mirror. The operation of such a motor becomes not only undesirable, but even dangerous.
  • The oil should not only lubricate, but also clean the interacting
  • . To a greater extent, this applies to synthetic fluids, the performance of which is one of the best on the market.

Manufacturers make oil for two-stroke engines colored. Dissolving in gasoline, it turns it into a pale pink or red color. So the operator can easily check if he (or someone from his team) forgot to prepare the mixture in the right proportion.

Engine oil

Without exception, all chainsaws, like their fellow lawn 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 through the use of 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.

You can’t spoil a saw with oil. But only good. Chainsaw lubricants overview

Chainsaw performance is impossible without fuel and quality lubrication. It makes no sense to buy an expensive model, which is reliable, and pour an unknown composition into it, like smelling of gasoline. The selection of oil for a chainsaw seems insignificant, but in fact it is very important for the normal operation of the tool.

Stihl HP Super

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.

Oleo-Mac Prosint 2T

High-quality semi-synthetics in bright packaging. not so little. But unlike cheaper counterparts, it has API TC approval. It is not necessary to understand this, it is enough just to know that such oil has passed the appropriate certification and test system.
