Advantages and disadvantages of oil
Any quality machine oil has its pros and cons.
Any quality lube has its pros and cons. Some experts say that any chainsaw oil will work. This is not entirely true, almost any substance can be used for the Khurstavna chainsaw, but for the Calm chainsaw only gear oil is required. When choosing, you need to know the color of the oil well, a two-stroke engine requires a composition that has a reddish, bluish or greenish tint.
To prepare the mixture yourself, you need to use a heat-resistant lubricant, which has a well-known brand name.
Seasonality affects the density of the product:
- Air temperature.
- Humidity.
- The intensity of solar radiation.
- Pressure.
What are the features of different oils, you can find out precisely by carefully studying the label on the container. In the absence of instructions or labels on the packaging, you should refuse to use such a substance. At the same time, the performance characteristics of the oil should not change dramatically with a difference in temperature conditions.
The specificity of the lubricant lies in the fact that it is optimal for engines with high rpm, which have air cooling. It is with such power plants that chainsaws are equipped. Oils of mineral origin have a reddish tint, and "synthetics" have a greenish tint.
You should not use any substitutes, often there are counterfeit products among them (up to 20%). It is quite difficult to distinguish a fake; you need to have special equipment.
It is recommended to store fuel in metal containers. It is best to prepare the fuel mixture in a canister.
There are a large number of oils and each has its own characteristics.
The consistency is done in the ratio:
Expert opinion
Vasily Kuznetsov
There are almost no chainsaws on the market that operate on a mixture in a ratio of 25: 1. After pouring a new mixture, the tool should run for a while at idle speed.
The performance characteristics of mineral or organic oils intended for the chain itself are not suitable for preparing the fuel mixture. The finished product is poured into the tank (up to half), then mixed (the container must be hermetically closed). Thus, a homogeneous composition is obtained. It is better not to prepare fuel ahead of time, it loses its functional properties quickly enough. At room temperature, the flammable liquid deteriorates within two weeks.
How to make the correct chain lubricant mixture
it is better to dilute the mixture 1:40
For self-preparation of the mixture, you need to use gasoline A-92 and A-95, if the octane number is lower, this can lead to engine breakdown. If gasoline has stood in a canister or other container for a long time, it is considered stale and loses its properties. Chainsaw on poor fuel will not be able to work powerfully and efficiently.
Experts advise to choose oil for most chainsaws that are used in our regions, having API-TB and API-TC classes, designed for two-stroke engines. You should not skimp on ingredients, but buy high-quality oils from well-known manufacturers and precisely observe the proportions for preparing the mixture.
If you add more oil to the mixture, it will lead to the formation of deposits in the candles and pistons. Excess gasoline will contribute to the appearance of seizure marks on the pistons and the rapid failure of the chainsaw engine. Before preparing the mixture, you need to read the instructions carefully for this model of technology.
It is not recommended to store ready-made mixtures for a long time, maximum 1 month; it cannot be kept open or in the sun. Water or dust trapped in the mixture can damage the carburetor as an installed filter cannot completely clean the fuel.

graduated canisters
You can also use simpler containers that are always at hand, for example, plastic bottles or glass, but static electricity arises in such objects. It is imperative to make sure that dust or moisture, solid particles do not get into the container, if all proportions are observed, then you need to mix everything well.
When the mixture is finally ready, it can be poured into the tank without carefully developing the fuel and so that it is not completely filled. Depending on the use of the chainsaw, you need to either completely use all the lubricant or drain it into a container and then refill it as needed, but no later than 30 days.
It is good to use various additives recommended by equipment manufacturers so that the fuel is of better quality. There are a lot of additives on sale and you can choose the one suitable for your chainsaw.

- The budget option is Nanotek Standard, which can be operated at temperatures up to -20 ° C, Nanotek Premium up to -30 ° C. Also in this category can be attributed a product from Enkor, with a capacity of 1 liter.
- Mineral oils with Bio attachment - Makita Biotop, Stihl Bio Plus.
- Oils recommended by chainsaw manufacturers - Makita Biotop, Makita, Oregon.
- In containers of large volumes - Enkor oil 3-5 liters, Stihl 5 liters, Oregon 5 and 25 liters.
Conclusion
The main task of creating a mixture for lubricating the chain is the uninterrupted operation of the engine, complete combustion of the fuel, so that as a result, smoke, soot or scuffs cannot form. Observance of the necessary proportions, correct operation and high-quality ingredients will help to use the chainsaw for various household tasks as long as possible.
How to refuel a chainsaw
Let's take a look at how to refuel your chainsaw. Failure to feed the saw correctly could pose a threat to the life and limb of the operator.
There are rules that must be followed when refueling the saw:
do not spill oil and fuel mixture;
the place where the saw will be refueled must be flat;
the place must be more than 2 m away from the area where the device will be used;
the site must be located away from fire; no smoking in this place;
while the fuel tank is being filled, you need to fill the oil tank, which is intended for automatic chain lubrication; you can distinguish containers by special icons;
before pouring, wipe the container necks with a rag;
during operation, grease and gasoline must not be spilled, so you need to be careful when unscrewing the canister caps; when refueling, it is better to use a funnel;
care should be taken when screwing the lid with the latch;
experts advise not to fill the container completely, but to leave some free space.
During the operation of a properly refueled chainsaw, it is necessary to regularly check the tightness of the containers and the operation of the motor. If the chain gets too hot, or gasoline is consumed too quickly (faster than oil), this should alert you. Before starting work, the chainsaw is run in.
With proper operation of the chainsaw, 1 tank of gasoline should be enough for 30 minutes of operating the device at maximum load. When gasoline runs out, there is still lubricant in the second container, but in a small amount.
Fuel and lubricants
Petrol
Engine manufacturers recommend using high-octane gasoline AI-92, 95. It is not allowed to use fuel with various additives to increase the octane number.During this time, the process of resinification and polymerization can take place in it, which negatively affects the operation of the engine.
Most chainsaw engines use leaded gasoline. If you have purchased a tool with a catalytic converter (the tank cap will be green), we recommend unleaded gasoline.
Butter
Air-cooled two-stroke motors do not have a separate lubrication system. Moving parts are lubricated with oil in the fuel mixture. Therefore, it is so necessary to use only high-quality oils from trusted manufacturers.
Recommended oils for refueling chainsaw:
- STIHL HP - specially developed for chainsaw engines. It has proven itself in all weather conditions and ensures perfect engine operation.
- Husqvarna HP is an oil from a renowned manufacturer of garden equipment. Special additives reduce carbon formation on the engine crankcase, which can occur due to the use of low-quality fuel.
- Oleo-Mac Prosint 2T is a multifunctional oil with synthetic esters. Protects engine parts from corrosion, reduces wear on mechanisms and parts.
- CHAMPION JASO FD is a quality oil from a well-known company. Provides good protection for all moving engine parts;
- Vitals Semisynthetic is a multigrade oil for budget models of chainsaws, intended for use at temperatures from -20 to + 40C.
How to dilute gasoline for a chainsaw
Consider how the mixture is prepared for a chainsaw. It is necessary to calculate the correct ratio of gasoline and oil for the chainsaw. For a chainsaw, they take fuel with a high octane index: AI-92 or AI-95.
To prepare the fuel mixture, it is necessary to add 30 g of oil to 1 liter of gasoline, which corresponds to the design of the saw. The resulting fuel fluid is poured into the fuel compartment. Before diluting gasoline, you should consult a service specialist who specializes in the repair of chainsaws.
In order for the saw to have a long service life, it is necessary to properly prepare a gasoline-oil mixture, for which only AI-92 and AI-95 brands can be used. The fuel must be unleaded, otherwise the internal combustion engine may break down. Do not use an old product that has expired, because over time, the fuel can change the octane number. The proportion of lubricant and fuel is strictly adhered to.
You should not save when choosing oil for chainsaws of the Husqvarna brand and others. The proportions must be observed due to the fact that excess oil can lead to the growth of carbon deposits on the chainsaw units. Excess gasoline can cause damage to the piston and damage to the internal combustion engine. So, 1 liter of fuel is mixed with 20-50 ml of oil. Husqvarna recommends adding 100 ml of lubricant to 4 liters of gasoline. This proportion is suitable for saws with a power of up to 1.5 kW.
For structures with a power of more than 1.5 kW, an oil ratio of 1:50 is used. That is, it is necessary to dilute gasoline like this: add 5 liters of gasoline for a chainsaw to 100 ml of oil. Partner recommends that when refueling the chainsaw, dilute the fuel fluid at the following rates: add 100 ml of lubricant to 3.3 liters of fuel.
When using supersynthetic oils, the indicators are 1: 100. That is, the fuel mixture for the chainsaw must be prepared according to the recipe: add 100 ml of lubricant to 1 liter of fuel. When choosing components, you must use the information that is given in the instructions for any modification of the saw.
Let's consider in which container the fuel can be mixed. There are canisters with graduated marks in stores, which have 2 holes: for fuel and for lubrication. Using such a canister, pour both ingredients, tighten the lids and mix the substances by tilting the canister in different directions.
Plastic bottles and other containers are often used to mix ingredients.Be careful with plastic and glass. Mixing the components may generate static electricity. Care must be taken to prevent pebbles, sand or water droplets from entering the fuel mixture. The fuel mixture must be mixed well. The prepared fuel mixture should not be stored for more than a month, as oxidation of the materials may occur and the composition of the mixture will change.
Engine breakdown, which was caused by expired fuel, is recognized in the services not under warranty. At the same time, the cost of repairs can reach 80% of the price of a new design.
After all work with the use of a chainsaw has been completed, you need to spend the remaining fuel, turn off the engine, and remove the remaining mixture.
For the best operation of the device, it is necessary to make a mixture that will ensure uninterrupted operation of the engine, complete combustion of the gasoline-oil mixture without the formation of carbon deposits, smoke or damage.
Oil for two-stroke engines of chainsaws
Lubrication of engine parts can ensure the proper operation of the factory mechanism only if it meets certain requirements.
These include:
- the ability to lubricate parts - the composition should create a uniform oily film that will penetrate into the smallest grooves of the engine, and also prevent friction of the internal combustion engine elements and exposure to high temperatures;
- smoke formation - good quality grease should not smoke. If black smoke comes out of the chainsaw muffler, then the engine lubricant must be replaced;
- no carbon deposits - during operation, the oil should not form carbon deposits, which, settling on the walls of both the carburetor and the muffler, reduces their performance and service life;
- detergent properties - while maintaining the engine's operation, the engine oil for the chainsaw should clean the walls and engine parts from accumulations of tar and dirt;
- the ability to work at extremely low and high temperatures - a high-quality lubricant for engine parts should not freeze in frost or boil in direct sunlight. It is best to choose formulations that are capable of working in the range from -20 to +40 ⁰C;
- the ability to protect against corrosion - when operating a chainsaw in conditions of high humidity, condensate inevitably seeps into the engine, which provokes the formation of rust. Engine oil should protect the internal combustion engine components from rust. For this, it must contain appropriate additives.
An important role in choosing a lubricant for an engine on your own is played by its type. Most often, you can find mineral and synthetic oils on sale. Means of the first type have a less balanced composition, which lacks most of the useful additives. Synthetic oil is more popular because it more reliably protects engine parts from wear, corrosion and carbon deposits. That is why synthetic grease is more expensive than mineral grease.
There are a number of oils that are popular with both general users and experienced fellers.
These include:
- Stihl HP - this grease shows high stability and reliable engine protection in all weather conditions. The oil resists corrosion well and practically does not smoke. The composition of the product contains all the additives necessary for the operation of the engine, including components that prevent the formation of carbon deposits;
- Stihl HP Ultra - belongs to the group of oils of the highest category. The product has excellent lubricating properties, good resistance to wear and corrosion. It contains ashless additives, which guarantees the absence of carbon deposits on the carburetor and muffler;
- Husqvarna HP - a product of this brand stands out for the presence in its composition of additives designed to compensate for the poor quality of gasoline used. The grease is made on a semi-synthetic basis and has a high resistance to corrosion.
When choosing oil for 2-stroke chainsaw engines, it is very important to study its shelf life in advance. It must be remembered that high-quality grease will not last more than 5 years, even if it is stored in a closed container.
Therefore, it is best to buy products that have a shelf life of 2–4 years.
Can 95 gasoline be poured into a chainsaw?
Almost 75% of manufacturers in the passport for chainsaw indicate that it is necessary to use AI-92 gasoline. Those owners of such equipment, who first encounter it and do not know what gasoline is needed for a chainsaw, draw parallels with car engines and conclude that the higher the octane number, the better. As a result, not understanding how to properly dilute gasoline for a chainsaw, they dilute AI-95 oil and gasoline.
The thing is that an increase in the octane number is achieved by introducing various additives into gasoline, as is done in AI-95 and AI-98 gasoline. For two-stroke engines, additives are harmful due to their special design, so you need to use AI-92 gasoline, especially in our country. Firstly, it is correct and will extend the life of the motor, and secondly, it is cheaper. But for some manufacturers, for example for Stihl, AI-95 can also be used, but it is better to take it at good proven gas stations.
Fuel mixture preparation instructions
We will find out in more detail how gasoline is diluted with oil. Some tool owners do this - pour clean gasoline into the tank, and add the required amount of oil. Then close the lid and mix. This method of diluting gasoline with oil is incorrect. Instructions for preparing a petrol-oil mixture are as follows:
- You need to take a plastic bottle of equal volume - 1 or 2 liters. You can use a 1.5 liter, but this can get confusing when adding oil.
- Fill the container with gasoline halfway.
- Add lubricant. It is recommended to dose the oil with a syringe. It is advisable to use a 5 cc syringe, which will accurately measure 25 ml of oil.
- After adding the lubricant to the container, shake thoroughly.
- Add gasoline until the container is full and mix thoroughly again.
- It turns out a ready-made gasoline-oil mixture for a chainsaw, which should be consumed within 1-2 weeks.
Many do not pay enough attention to storing the prepared mixture, and therefore can immediately prepare 5 liters and use it throughout the year. However, this approach is extremely incorrect, since the shelf life of the finished mixture is 15 days. If you are sure that the gasoline does not contain alcohol, then you can store the finished mixture for longer - up to 3 months. After that, the mixture loses its properties, having a negative effect on the internal combustion engine.
Interesting to know! Make it a rule not to prepare too much fuel for your chainsaw. It is better to cook 2 times one liter at a time than immediately mix 2 liters, which will remain and will be stored indefinitely.
After combining gasoline with oil, it remains only to fill the tool and start using it. There are some important points to consider when refueling your chainsaw. We will understand them.
How much oil do you need to add to gasoline?
Types of oils used for dilution in gasoline
Chainsaws do not have oil pumps, so combustible mixture alone cannot be used. You should carefully read the instructions that are attached by the manufacturer to each product. There is a lot of information on the Internet, it is not difficult to find it.
If there is no lubrication, the saw will fail after a short time. It is recommended to do preventive maintenance of the unit, fill in properly diluted fuel, in this case the tool will function for many years.
You should carefully read the recommendations from the manufacturer (see."Instruction"), it always signs in detail: what composition is required for the power plant. It is not worth saving on oil, the benefit is small, and the engine resource can be significantly reduced. Tool repair is expensive, up to 85% of its cost.
If we take, for example, the Husqvarna chainsaw, then unleaded gasoline with the first addition of grade 92 is suitable. If the composition has a greenish color, then this indicates that the product is of the premium class. AI-92 is the optimal product that can be suitable for such a device. On average, professionals advise adding 20 to 50 ml of machine oil per liter. If the power of the unit is one and a half kilowatts, then only 25-27 ml of oil is required.
Expert opinion
Vasily Kuznetsov
If the instrument is more powerful, then about 30 ml of oil is required, and in some cases even more.
How to dilute engine oil and gasoline, in what proportions? This question arises for all users. First you need to stock up on containers:
The process of mixing oil and gasoline is technologically uncomplicated
It is important to observe safety precautions so that static electricity does not accumulate, not a drop of water gets into the fuel.
Types of oils used for dilution in gasoline
What proportions should be done? The engines are mostly two-stroke, so the mixture is usually 1:50. Russian-made chainsaws function with products of the following brands:
- M8-B
- M-12TPU
- TP
- MGD-14M
For foreign analogues, it is permissible to use two liters of gasoline per 80 grams of oil. Foreign saws are distinguished by economical fuel consumption, the proportions of oil in them vary from 40 to 49 shares.
Shades of oil can vary significantly, this should be taken into account during operation. For example, HP produces reddish engine oil. If the composition has a greenish (sometimes blue) tint, then this is a sure sign that the product is synthetic premium. The quality of such compositions is high, the cost is also rather big.
