What Oil To Pour In Gasoline For Chainsaw
Choice of oil for chain lubrication
In addition to the engine, for which all the proportions of oil and gasoline for the Stihl chainsaw have already been found out, there is another important part, consisting of many moving links. the chain. For its lubrication, not motor oil, but chain oil is used. It has completely different properties and is cheaper.
For a new tool, only oils from the manufacturer are used, which are recommended in the instructions. Otherwise, if the saw breaks down, it will be removed from the warranty service due to non-observance of the operating conditions. It should be noted that the oils from the manufacturer are of really high quality. After the end of the warranty period, you can use any engine oil, making it change twice a year.
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.
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, oil envelops the cylinder walls and reduces the friction of the piston rings.
The engine of the chainsaw is high-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 a section 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.
Shelf life of the finished fuel mixture
Motorists know that it is not worth storing gasoline for a long time, and the finished fuel mixture deteriorates even faster. It is necessary to mix the required proportions of oil and gasoline for the Stihl chainsaw before starting work. Manufacturers allow storage of finished fuel up to one month, and experts recommend reducing this period to 10 days. Immediately after mixing, the solution begins to lose its original properties and over time it becomes not at all of the same quality as it was prepared. Learn to prepare enough saw fuel to be consumed in one go. It comes with experience. The mixture should be stored in a gasoline-resistant, opaque, tightly closed container. For this, any canisters made of plastic metal for combustible materials are suitable. And also use a container of oil or glass containers made of dark glass.
- 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 a burning mixture, this will negatively affect the exhaust system and, alternatively, the health of the operator.
- Third, chainsaw lubricant should burn with minimal carbon deposits. 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, up 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.
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.
Which brand to use motor oil?
For each model, the manufacturer advises a list of materials to be used. It is better for the user to adhere to these recommendations, because the warranty does not cover tool breakage due to inappropriate fuel and lubricant. In this case, the owner himself pays for the repair of the chainsaw, which can be up to 80% of its cost. When you can’t follow the manufacturer’s recommendations, try to follow these rules:
- Use oil only for 2-stroke engines.
- Do not use after expiration date.
- Do not add used oil with a large amount of impurity to gasoline, as the mechanisms of the tool can be damaged.
- Chain lubricant cannot be used for fuel mixture.
- It is preferable to use synthetic and semi-synthetic oils, which are more expensive than mineral oils, but do not form harmful deposits.
Stihl adhesive oils
The company’s website contains the following adhesive oils designed for various operating temperatures and having a good lubricating performance:

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 analogues, 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 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.

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 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.
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 the middle ground between quality and price.
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 chain saw tire sprocket 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.
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 hide it. So, back to the manufacturers, and start with the popular Stihl brand.
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 safe for the environment, 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.
