Main manufacturers
Leading manufacturers of chainsaws produce consumables and lubricants for them, including those specifically for chains and tires. All other things being equal, you should give preference to the products of the manufacturer of the chainsaw itself. But the quality of the best brands is such that the use of lubricants from another manufacturer will not have a negative impact on the work.
The most famous brands are German Stihl, Swedish Husqvarna and Japanese Makita. They provide a fairly wide range of adhesive oils, including the following:
- mineral Stihl ForestPlus is designed to work at temperatures up to 15 ℃. Standard packing. 1 and 5 liters. For long-term work, it has recently been produced in a 20-liter container;
- highly sustainable Stihl BioPlus is plant-based. Once in the soil, it quickly decomposes without contaminating it. The working temperature is also up to 15 ℃. Packing. 1 and 3 liters;
- semi-synthetic Stihl SynthPlus is suitable for low temperatures, working usable up to 25 °.
- Eco-friendly, biodegradable Bio and Bio Advanced. It is presented as a universal multigrade oil. Bio Advanced option. improved oxidation resistance and up to 10% better lubricating properties;
- Makita. Biotop oil;
- adhesive oil Champion.
Of the Russian brands, especially for chains, there is ZUBR ZMPM-M. There are other, less well-known manufacturers, whose lubricating oil is significantly lower in price.
When and how to fill
Where to fill the chain oil is clear. There is a separate container for this. In most chainsaws, the size of this container is calculated taking into account the volume of the saw’s gas tank. When both tanks are full, they empty at about the same time. Therefore, it is recommended to fill the full volume of the oil tank at the same time as filling the fuel tank. Then you don’t have to be distracted by topping up twice.
Before starting work, it is useful to check if oil will flow to the chain. To do this, it is enough to direct the end of the tire onto a flat surface. Some of the grease will fly off the edge of the tire. Droplets on the surface indicate that the system is operating normally.
At high negative temperatures, summer oil thickens and its lubricity deteriorates. Therefore, it is worth using brands designed for winter conditions. If this is not possible, then it is worth taking the time to dilute the existing oil to reduce its thickness. It is best to dilute with kerosene in a ratio of 1 to 4.
Some models have an adjustable feed rate in the lubrication system. It is useful for correcting in the event of a change in the type of grease.
Note! Do not fill the tank with a mixture of oils of different types. mineral and synthetic.
If the oil from one manufacturer has run out, but the same type is available, but from a different company, then their mixing is allowed, provided that they are used immediately. Leaving such a mixture for a long time is not worth it.
What kind of oil should you use
It is widely believed that quality branded chainsaw oil should only be used in the engine’s gasoline-oil mixture. However, the choice of oil for lubrication is a simple matter. Anyone will do, as long as it gets to the right place.
But adding lubricant to the chain is half the battle. It is necessary that it hold on to the metal and remain on the lower edge, with which the tree is sawn. For this purpose, substances with increased adhesion are used, that is, the ability to adhere to the surface and adhere to it. Oil with poor adhesion will fly off the rapidly rotating chain, splattering around uselessly. Of course, some part will remain, but it is not known whether this will be enough so that during intensive work the circuit does not overheat.
Important! During all-season operation with a chainsaw, it is necessary to take into account the dependence of the oil supply conditions on the season and air temperature.
Mineral materials that provide chain and bar lubrication at freezing temperatures crystallize and thicken in the cold. This leads to the fact that the lubrication will be difficult to supply and the load on the oil pump will increase. Its service life is shortened and it may fail prematurely. In winter, it is necessary to choose synthetic materials with special additives that provide reliable lubrication in frosts down to 40 ℃. At low frosts and temperatures near zero, semi-synthetics are used.
Estimates of the use of different oils for lubricating chainsaw chains boil down to the fact that the wrong choice can increase the engine load by up to 10%. The service life of the chain and guide bar is further reduced.
Due to the fact that in recent years great importance has been attached to ecology, more and more branded oil products are made on the basis of decomposable substances. But during long-term operation, the consumption of chain lubrication can be measured in liters. And for people who are not indifferent to nature, this will be another reason to choose an environmentally friendly product. If you do not care what your site is sprayed with and what marks remain on the wood after cutting.
Sprocket grease
At the end of the chainsaw bar, there is a driven sprocket that rotates the chain. It also needs to be lubricated periodically. For this, thick materials are used. Stihl multipurpose grease can be used. Domestic lithol-based lubricants are also suitable. There is a special hole on the sprocket lubrication tire. You need to pump grease into it with a grease can or a syringe.

It should be noted that with frequent use of the tire toe, for example, when cutting grooves, the load on the sprocket increases and it needs to be lubricated more often.
Chainsaw chain oil selection rules
All modern chainsaws have a separate oil circuit for lubricating the cutting elements of the chain.
The quality of the saws largely depends on their condition and working conditions. Therefore, companies that produce accessories for chainsaws create special brands of oils that provide reliable surface lubrication.

How to replace expensive oil
Special branded chain lubricants have the disadvantage of their high price. It is not burdensome to buy a liter of other expensive oil. And if work is coming that requires several liters, or even tens of liters, thoughts of saving will certainly arise. The main thing is not to go to extremes when considering options. You can save on oil to such an extent that you will have to change the chain several times, or even the tire itself or the oil pump.
Chainsaw Basics: Fuel and Oil
There are three replacement options. Firstly, specialized products of little-known manufacturers can be used for chain lubrication. But such oils still need to be looked for. In addition, there is a risk of stumbling upon a low-quality product.
Application of oils for automobile engines. They can be used as a temporary replacement, but they cannot boast of high adhesion, so the quality of their work will be clearly worse than special ones. For this reason, it is not recommended to use spindle and diesel oils. the worst in adhesion.
And I must definitely say about one more option. working off. This is the name of the oil that has worked out its life in the engine and is drained from it when it is replaced.
In fact, this is not an option at all. Metal particles are always present in mining. And if they may not damage the chain itself, then they certainly will not damage the oil pump and the entire lubrication system. On forums on the Internet, you can find a “killer” argument in favor of working off. that the Soviet Druzhba chainsaw did not have chain lubrication at all and worked. So you can pour anything. and so it will do. Well, Stihl will also work with a working off or even with a non-lubricated chain. The question is how long it will work and how many chains will have to be changed during this period.
Caution for those who have a chainsaw within the warranty period. Masters of warranty workshops are able to identify cases of use of low-quality chain lubrication. Especially when using mining. Repairs under warranty will be denied immediately.
Oil does not flow to the chain, what are the reasons
It is not always during operation that you can immediately see that no oil is supplied to the chainsaw chain. Signs of lack of lubrication:
- the level in the tank does not drop;
- cutting is difficult, accompanied by the smell of burnt wood;
- oil droplets do not fly off the tip of the chainsaw tire.
Having found a malfunction of the oil system, you need to establish its cause. There are few of them. clogging, broken hose or malfunction of the oil pump.
Most often, the oil supply channel is clogged with dirt and sawdust. Air blowing or fine wire cleaning is sufficient to correct the fault. The oil reservoir has its own internal filter. When using normal oil, clogging is unlikely, and when filling, it is quite possible. Have to clean up.
The oil hose may be damaged or completely cut off. You can temporarily seal the damaged area, but it will be safer to replace it with a new one.
And the most serious problem is the breakdown of the oil pump. The reasons may be different. the teeth of the worm gear are worn out, the plunger has jammed, and others. Removing the pump and replacing a damaged part yourself will not be easy. It is safer and easier to contact the service center.
One of the important indicators of the durability of chainsaws and their high-quality operation is the correct observance of the ratios of the constituent liquids when preparing the fuel mixture. It is known that an insufficient amount of oil leads to excessive friction of parts and their rapid wear, and excess oil leads to the appearance of carbon deposits and overheating of the engine. This article will discuss the proportions of oil and gasoline for the Stihl chainsaw. This is especially important for beginners who have just purchased a tool.
Correct proportions
Most often, when preparing fuel for saw operation, proportions of 1:50 and 1:40 are used. This means that for 50 or 40 parts of gasoline, one part of oil is added. Calculations are made as follows: 1 l = 1000 ml, 1000/50 = 20 ml or 1000/40 = 25 ml, that is, in the first case, pour 20 ml into each liter of gasoline, and in the second. 25 ml of oil. If there are no instructions and you do not know the proportions for preparing the mixture, then use the following recommendations:
- Tool and oil from the same brand. For example, for a Stihl chainsaw, the ratio of gasoline to Stihl oil will be the same as indicated on the container with oil, usually 1:50.
- The substances used for the mixture have different brands. a ratio of 1:40 is chosen.
- There is only one brand, but there is no information on the ratios of substances in the oil. they dilute 1:40.
- In the absence of any data on saw and oil, dilute the mixture in a ratio of 1:40. The only thing to make sure that the oil is designed for two-stroke engines.
To run a new saw in the first three refueling of the fuel tank, add 20% more oil. In this case, instead of a ratio of 1:50, it will be 1:42, and the ratio of 1:40 turns into 1:33. A liter of gasoline will require 24 or 33 ml of oil, respectively. No other running-in measures are carried out with the new saw. Manufacturers advise to work only at the highest speed at all times. After running in the tool, use the usual proportions of 1:50 or 1:40. In some cases, the manufacturer of the equipment indicates other ratios, for example, 1:25 or 1:32, they must be observed.
How to prepare the mixture?
In order for the equipment to serve for a long time and properly cope with its functions, you need to know exactly how much oil you need to add to gasoline for the Stihl chainsaw. Earlier, we found out that it is better to use a lubricant product from the manufacturer Stihl and unleaded AI92 or AI95 gasoline as components. Leaded fuel grades adversely affect the operation of the unit and disable it. With these components, 20 ml of oil is added to the mixture per liter of gasoline. Any violation of the proportions leads to the appearance of carbon deposits on the spark plugs and pistons, as well as the formation of scoring. The oils used can be green, blue or red.
Their presence is easily determined by the color of the mixture. To dilute fuel, often complete with equipment, a special canister is attached. These containers have graduated marks and two holes. The user only needs to fill the tank with the components of the mixture to the required marks, close the lids and mix. Some people use plastic bottles and syringes to measure oil for this purpose. In this case, it is necessary to ensure that foreign particles or water do not get into the container, all this will worsen the operation of the engine.
Advice
Tips and life hacks are extremely useful in practical work, consider some of them:
- It is convenient to use canisters with dispensers, while experienced people filter gasoline through suede. The cleaner the fuel, the better the carburetor will work.
- Gasoline can actively evaporate, especially at high temperatures, a suspension falls out at the bottom of the canister, which cannot be poured into the engine.
- It is recommended to prepare fuel for no more than three operational fillings.
- The quality of the fuel can be affected by the material of the container, especially PVC materials react actively.
- If the combustible mixture is poured of poor quality, the chainsaw may be removed from the warranty.
- During operation, it is necessary to test the tightness of containers and the rhythmic operation of the engine.
- One of the first signs of a malfunction is undue heating of the circuit.
- Before subjecting the tool to severe stress, it should be tested at idle speed.
- The tank is enough when working for half an hour.
- There is still grease (residues) in the second container when it has run out in the tank.
- If a large amount of smoke is generated during operation, this means that the fuel is of poor quality.
- During the operation of the unit, do not approach an open fire.
- (distance up to 2 meters).
- Fuel should not be poured “under the rim”, leave a little space.
The highest quality product is considered to be the product of Husqvarna, followed by Lukoil machine oil.
The advantages of these oils:
- Low consumption.
- Maintaining quality.
- Ability to maintain technological qualities for a long time.
- Can work in extreme conditions.
- No toxins.
- Minimum amount of carbon deposits.
Many professional tools use a lubricant made using API-TB technology (USA). Products made according to the JASO-FB method (Japan) are also popular.
It is permissible to mix oils from different brand manufacturers with similar characteristics. Mineral and synthetic oils are incompatible. The best oil for household chainsaws is considered “Standard”, for professional equipment the technical fluid “Ultra” is optimal.
Some oils can successfully replace each other. For example, substances produced by Husqvarna and Stihl. Lubrication for scooter engines or motor boats is not suitable for chainsaws, the oil quality in them is low. If the proportions of oil and gasoline are not maintained, then the tool will quickly fail due to the abundant formation of carbon deposits.
Risks of using fuel and oil surrogates
Thus, mixing counterfeits will significantly worsen the condition and operation of the tool, causing premature breakdowns, in special situations, complete failure.
For this reason, it is necessary to be especially careful about what kind of oil and gasoline to buy.
What gasoline should you use for your chainsaw? How to breed it correctly?
The chainsaw is simple to operate and is sometimes needed in a private household. The device cannot fully function if you do not use the correct fuel mixture, which you should be able to prepare.
Chainsaw fuel mixture: how much oil is needed per liter of gasoline
Any gasoline equipment will perform work properly only if the operating rules and the correct preparation of the fuel mixture are taken into account. This feature also applies to chainsaws. How much oil per liter of fuel to use for refueling and how to properly prepare fuel, we will analyze in more detail.
The proportion of oil and gasoline for the Stihl chainsaw: types of oil, the choice of gasoline and the correct mixing

One of the important indicators of the durability of chainsaws and their high-quality operation is the correct observance of the ratios of the constituent liquids when preparing the fuel mixture. It is known that an insufficient amount of oil leads to excessive friction of parts and their rapid wear, and excess oil leads to the appearance of carbon deposits and overheating of the engine. This article will discuss the proportions of oil and gasoline for the Stihl chainsaw. This is especially important for beginners who have just purchased a tool.
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 that 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.
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 cans made of plastic metal for combustible materials are suitable. And also use a container of oil or glass containers made of dark glass.
Chainsaw “Stihl”: which gasoline oil to use?
A number of manufacturers that produce equipment also develop their own consumables that are adapted to the operation of a particular engine. So the Stihl company produces oil exclusively for its equipment. It is equipped with special additives that can compensate for the quality of the fuel, improving lubrication and cleaning of the fuel mixture. It should be noted that Husqvarna HP oil is universal and can be used for all chainsaws. It can be applied at a temperature not lower than 10 degrees.
And also for two-stroke engines, products of the following brands are used: Sadko, Kraissmann, Oleo-mac Prosint. If you use a Stihl chainsaw, how much oil should you add per liter of gasoline? The ratio will be 25 ml of additive per liter of fuel. It must be remembered that there are oils for chains and motors. They are intended for different purposes and are not interchangeable. The use of chain oil for the preparation of a combustible and lubricating mixture leads to tool breakage.
Fuel selection
Which fuel to choose for a chainsaw is a non-idle question, the success of the unit directly depends on it. According to existing canons, good gasoline for a chainsaw is considered not leaded, but high-octane from a trusted manufacturer. The cleaner the fuel, the better. If gasoline has been stored in a canister for a year or a year and a half, this will adversely affect the nature of the device’s operation, therefore, the substance should be prepared before starting work.
It is important to monitor that there is no alcohol in the fuel, any additives that can disrupt the functioning of the power plant. Experts are still debating which is better than 95 or 92. The first has more stable detonation indicators, but most often the 92nd is still used. The reason is simple: questions often arise by the 95th, it contains a large number of various additives that have a bad effect on the operation of the saw engine. Micro-knock occurs (piston impulse in the opposite direction), which occurs practically at every revolution of the crankshaft. If the octane number is even higher (98), then the micro impacts will become even more intense.
The consequences of improper gasoline on the quality of the unit can only be negative:
- The mechanism will be difficult to start.
- The power will be minimal.
- Parts will wear more intensively.
Consumer reviews of Stihl saws are mostly positive. It is lightweight and affordable. There are some complaints about the low power of the instrument. But for occasional use at home, it is quite suitable. And if you use the correct proportions of oil and gasoline for your Stihl chainsaw, it will last for many years.
