At What Proportion To Breed Chainsaw Oil
The ratio of gasoline and oil for chainsaws
Household and professional chainsaws are powered by two-stroke ICEs operating on a dosed mixture of gasoline and engine oil adapted to the difficult operating conditions. The correct proportions of oil and gasoline for a chainsaw is one of the important conditions for stable traction characteristics of the engine and low-cost development of its assigned resource.
The need to obtain a sufficiently high power from a small-cubic power unit makes it necessary to operate gas-powered engines in high-speed modes, therefore, increased demands are placed on the quality of both components of the fuel mixture.
The main component of the fuel mixture for gasoline-powered engines is gasoline with an octane rating of at least 92. Consumables with expired storage made on the basis of gas condensate with water and mechanical impurities are not suitable for fuel preparation.
- Opinions of experts on the use of gasoline of various brands are mixed. On the one hand, incomplete compliance of domestic A-92 gasoline with European standards is recognized.
- On the other hand, the quality of A-95 gasoline is questioned because of the high content of anti-knock additives. Use this fuel for the preparation of fuel for a chainsaw is possible only with full confidence in its quality.
- The difficulty lies in the presence of various improving additives, with the help of which unscrupulous manufacturers and distributors increase the operational properties of motor gasoline with a lower octane rating.
Irreversible changes in the working properties of the fuel also occur when it is stored for a sufficiently long time in a plastic container, regardless of the level of its benzo and oil resistance.
stringent selection criteria for the oil component. In the best case, this is a mineral or semi-synthetic engine oil recommended by the manufacturer, intended for use in high-speed two-stroke ICE with air cooling.
The advantage of mineral oils in their lower cost. Their more expensive semisynthetic and synthetic analogues are favorably distinguished by improved performance and compliance with environmental standards.
- keep working properties in a wide range of working temperatures;
- do not form soot;
- contain detergents, antioxidants, preservatives and other additives useful for the operation of the power unit.
Benefits of Branded Oils
Many domestic and foreign manufacturers specialize in the production of special motor oils, but Stihl, Husqvarna and Makita branded products have the highest ratings.
Only in certain parameters are domestic motor oils of the Lukoil trademark inferior to the branded assortment.
→ HUSQVARNA AT THE BEST PRICE list of the benefits of branded motor oils:
- economical consumption;
- stability of performance in difficult operating conditions and during long-term storage;
- minimum amount of toxic compounds in exhaust gases;
- almost complete absence of soot.
According to the American classification, API-TB oils can be used to work in household and professional models. The Japanese counterpart is JASO-FB and JASO FD. The preparation of a combustible mixture using oil for 4-stroke engines is strictly excluded.
Red, green or any other color of oil determines whether the product belongs to the assortment of a particular manufacturer, therefore, it is not taken into account when determining the characteristics of the material. Extremely cautious should approach the choice of engine oil of unknown composition and origin.
Before receiving additional information about the quality and operational parameters, it is better to temporarily refuse to use such material.
It is allowed to mix motor oils of the same types and composition for the production of well-known brands of the quality of their assortment. Under no circumstances is it permitted to mix mineral and synthetic oils.
A large assortment allows you to choose oil that fully meets the class and characteristics of the chainsaw, the conditions for its subsequent operation.
- For budget models, you can use oils of the Standard category, for professional chainsaws, lubricants of the Super and Ultra categories are recommended.
- To prepare a complete fuel mixture for a chainsaw, it is advisable to use branded oils recommended by the instruction manual or their brand analogues. In particular, Stihl and Husqvarna engine oils of the same composition and application are completely interchangeable.
Experts recommend that owners of chainsaws exclude motor oils intended for two-stroke engines of mopeds, boat engines and other mechanized appliances of the household group from the spotlight.
The power units of this equipment operate in more comfortable conditions, which makes the requirements for their operational characteristics less stringent.
Chinese oil dosage
Many Chinese-made chainsaws are simplified copies of popular models of European design. No special materials and proprietary technologies helps preserve legacy proportion of gasoline and oil in a ratio of 25: 1.
Twice the consumption of engine oil is offset by its lower cost. According to the assurance of the developers, the original components are introduced into the composition of Chinese oils, which contribute to increasing the wear resistance of power units and real extension of their assigned resource.
According to independent experts, the best brands of Chinese motor lubricants in quality correspond to analogues of European manufacturers in the mid-price range. This is the level of standard engine oils of the Standard group and partially Super.
Small private companies from China and other Asian countries specialize in the production of motor oils, which are sold at less cost in the markets under the brand name of leading manufacturers.
- Characteristics of fake products are much lower than branded originals. The constant use of counterfeit negatively affects the operation of the chainsaw and the durability of its operation.
- Only an experienced specialist can determine the status and quality of the oil, so you can avoid possible risks by buying consumables in a network of branded and licensed outlets.
- The use of substandard lubricants for service specialists is a legitimate reason for depriving the owner of a faulty saw of warranty repair and restoration obligations.
The working proportions of the fuel mixture
The standard ratio of gasoline and oil in the fuel mixture for chainsaw carburetor engines of different models is 40: 1 and 50: 1. This proportion provides a complete lubrication of the rubbing parts of the crank mechanism and piston group, and also does not prevent the complete combustion of the gasoline-air mixture.
Taking into account external factors, the fuel mixture can be adjusted in the direction of increasing the amount of oil. Such a need arises at the stage of running in a new tool, as well as at high air temperature. In this case, the standard dosage of oil is increased by 20%.
In practice, an increase in the percentage of oil in the fuel mixture is applied if its characteristics do not fully meet the stated requirements. How much oil per liter of gasoline is needed in each case, the sawmill determines.
→ CHEAP ANALOGUE FOR THE BEST PRICE
To maintain the correct proportion of gasoline and oil, a spreadsheet applied to the saw body may be used. The branded packaging of leading manufacturers of motor oils is equipped with built-in measuring devices that provide an accurate dosage of oil for different volumes of the fuel mixture.
Measuring utensils included in the original set of many models of chainsaws budget category. In some cases, dilute gasoline and oil in a predetermined proportion will medical syringe volume of 20 cm3.
Features of the preparation and storage of the fuel mixture
Safety regulations require that gasoline and oil be diluted in a metal canister. This eliminates the risks of static electricity and fuel ignition.
Experts advise pouring oil into an incomplete container, mix thoroughly, and then add pure gasoline to a predetermined level. It should be excluded from everyday practice the saving of working time by preparing the working mixture directly in the gas tank of a chainsaw.
This technology is fraught with fuel system failures due to the ingress of a large amount of oil into the carburetor, the need for disassembly and thorough washing.
It is better to cook the mixture in an amount that should be enough to perform one-time work. The problem lies in the irreversible deterioration of the working properties of the mixture during storage. The finished composition is recommended to be used over the next few days.
A mixture of gasoline with a monthly oil degrades the engine’s traction capabilities. There is also the formation of resinous compounds in the fuel system and intense carbon formation in the combustion chamber, the loss of mobility of the piston rings.
- With minimal damage to quality, it is advisable to store gasoline with oil for no more than 2 weeks. At an ambient temperature of 25 or more degrees heat, this period is reduced to 8-10 days.
- In order to save, the expired mixture can be gradually spent, mixing in a fresh composition in an amount of not more than 10% of the total volume.
In order to avoid problems associated with the failure of the fuel system, it is recommended to filter the prepared mixture through non-fiber material such as suede, or fine-mesh twill weaving, a metal mesh.
Features of running a new tool
This concept includes the gentle operation of a chainsaw at the initial stage of its operation. The technology also provides for engine operation on a mixture with a 20% increase in engine oil content.
Break-in time in hours is indicated in the attached instructions. In practice, for the tool to reach the working level, it is enough to develop 3-5 gas stations for the saw’s gas tank.
New models do not need a run-in, but the first hours of operation of the chainsaw are not recommended for use with heavy loads.

Dear friends and site visitors!
Thank you for your views of the content, I hope that you find useful information on the site about tools. Today I want to ask you for help for my friend Mikhail Pogorelov, who was in trouble. His two-year-old daughter Snezhana was diagnosed with the "Sensoneural hearing loss" disease. The degree of the disease is quite high, and the baby loses hearing every day. Parents collect on a hearing aid, but in addition to it, the baby will need an operation for both ears, the cost of which is simply sky-high. 30 thousand euros for one ear. Parents raise funds to do the operation in the near future, as the older the baby becomes, the more she loses contact with the outside world. I ask for the help of everyone who can and possibly who knows Mikhail. Baby wants to hear this beautiful World, so let’s help her.
You can provide assistance by transferring any amount of funds to Michael’s bank account:

Pogorelov Mikhail Andreevich
Thank you all personally from me.
The chainsaws of various companies are based on a two-stroke internal combustion engine, which drives the cutting headset of the tool. To activate the internal combustion engine, the proportions of gasoline and chainsaw oil are used. Combining gasoline with oil is a must, so if you just bought a tool, you need to understand the features of its refueling.
Dilute gasoline with oil to avoid failure of the internal combustion engine. The reason for this is the design features of the lubrication system of two-stroke engines. In the design of such engines there is no chamber for filling engine oil, and if fuel is filled without lubricant, the crankshaft, piston, bearings and connecting rods will not receive lubrication. This will significantly reduce the service life of all of these parts, therefore it is forbidden to fill clean fuel.
The recipe for the fuel mixture for chainsaws
Gasoline and chainsaw oil must be filled in appropriate proportions, which makes it possible to effectively lubricate rubbing parts. Lack of lubricant or its excess will lead to negative consequences in the form of carbon deposits. In order for the tool to work properly, you need to refuel it not only with high-quality materials from the first day of operation, but also observe the correct proportions.
It’s important to know! It is required to fill gasoline with an octane rating of at least 92 in a two-stroke engine. Many experts argue that Russian or Ukrainian fuel can only be filled with an octane rating of at least 95, due to its low quality.
For the engine to work properly, the main thing is to fill in clean fuel without pollution.
The ratio of gasoline and oil for chainsaws
The proportions of oil and gasoline for refueling two-stroke engines of chainsaws of different brands is 40 to 1 or 50 to 1. This ratio is standard, which is used not only by beginners, but also by experienced filers. It is this ratio for the preparation of the fuel mixture that is close to ideal, and provides lubrication of the rubbing parts of the crank mechanism and piston.

The proportions of the fuel mixture
It is interesting! Before mixing petroleum products, external factors should be considered. If the chainsaw is new, then it requires a break-in, and for this you need to add 20% more to the fuel oil than the standard values. 20% more lubricant also needs to be added if tool work is carried out at low temperatures.
How much oil do you need to pour in gasoline in milliliters? Per ml ratio of oil and gasoline 1 to 50 is 20 ml per 1 liter. In order to prepare the right mixture, pour 1 liter of gasoline into a plastic bottle and dilute it with 20 ml of oil. To correctly measure how much oil to pour, you should take a special measuring container and fill it to the appropriate mark. If it is immediately planned to prepare 2 liters of fuel, then 40 ml of lubricant must be added to this amount of gasoline.
There are other ratios offered by different manufacturers. These values of the ratios differ slightly, but if you subtracted other values in the passport to the tool, then you need to stick to them. Values of 1 to 50 or 40 are standardized. Pour 15 ml of oil per 1 liter of fuel in the summer, and in the winter add at least 20-25 ml. Knowing the recipe for the preparation of the mixture, you should also figure out the question of which gasoline to pour into the chainsaw?
Gasoline and chainsaw oil. which is better
Often, beginners ask, which is better to take gas for your tool? In order not to make a mistake in the selection, it is recommended that you read the instructions for the tool. In the instructions, each manufacturer indicates the corresponding brand of fuel. If the manufacturer indicates that the octane should not be lower than 95, it is not recommended to pour 92 gasoline.
How to prepare the fuel mixture for two-stroke engines
It’s important to know! It is necessary to distinguish that manufacturers produce two types of lubricants for chainsaws. for chains and engines. Chain materials are poured into a separate tank of the tool, and they are expended on chain lubrication during operation of the chainsaw.
Engine oils for two-stroke engines are produced by such manufacturers:
Usually, the ratio is indicated on the bottle with lubricant, so it will be difficult even for beginners to get confused with the preparation of the fuel mixture. Under no circumstances should you use refining even as chain lubricant. This will lead to the fact that soon it will be necessary to carry out tool repairs.
Instructions for refueling a chainsaw
Knowing the ratio of the preparation of the benzo-oil mixture, you can proceed to refuel it. The fueling instruction is as follows:
- First you need to prepare the mixture. Combining the two main components, mix them thoroughly.
- Place the tool on a clean and even surface. Before unscrewing the gas tank cap, it is necessary to clean or blow off sawdust, dust and dirt
- The neck of the tank should look up
- Install a small watering can in the neck, then pour fuel
- Control the refueling process, as the tank volume is small, so it quickly fills up
- Fill up to a full maximum, as when you close the tank lid, the remaining fuel will splash out
- After the fuel is poured into the tank, immediately add lubricant to the chain
- Fuel consumption and chain lubrication are approximately the same, therefore both tanks must be refilled
- After refueling, you can start to start the engine
The ratio of substances for cooking fuel
It is better to start the engine not at the place where the refueling was carried out, but to move to a distance of 2-3 m. The tool is ready to work, and you can start to start it. How the chainsaw engine starts can be found in this material (link).
What will happen if you pour mining into a chainsaw
If you do not want your chainsaw to fail at the wrong time, use only high-quality fuels and lubricants. It is forbidden to mix mining with gasoline. The reasons for this are the following factors:
- Another viscosity of the material, so mining is not able to provide effective lubrication of rubbing parts and mechanisms
- The mining contains small metal particles and chips, which, falling into the tank, will lead to clogging of the fuel filter and channel. If grease enters the cylinder with small particles, they will leave their mark in the form of accelerated wear on the piston rings
- Emission of a large amount of black smoke, which indicates the burning of oil
Surrogate materials cannot be poured not only into the tank with gasoline, but also into the tank for chain lubrication. What will happen if you use mining in the tank to lubricate the chain, you can see in the video.
Using the instructions, you can independently prepare the correct fuel mixture, on which the chainsaw will work. With improper dilution of the fuel mixture, not only the tool life is reduced, but its performance is also reduced.

Proportions of oil and gasoline for a chainsaw: what to use, ratio, how to pour, dilute
A chainsaw is started by means of an engine running on a mixture of gasoline and adapted to environmental conditions oil. It is necessary to observe the proportions of oil and gasoline for the chainsaw, then the device will work stably. To achieve high power, the saw is used in working at high engine speeds. Therefore, high demands are placed on the quality of lubricant and fuel.
What gasoline to fill in a chainsaw
Find out which fuel is recommended for this type of device. Since there is a 2t (two-stroke) motor on chainsaws, and it is impossible to put an oil pump on it, clean gasoline for saws is prohibited. A fuel mixture of fuel and oil is poured into the saws. The rules for refueling chainsaws of different models are regulated by the manufacturer.
Consider what kind of gasoline to pour into a chainsaw, experts advise. Chainsaw refueling is carried out with fuel with an octane rating of more than 92. To create a mixture, do not use fuel with an expired shelf life made of condensate, which includes water and various impurities.
Domestic saws are powered by AI-80 fuel. For foreign modifications, AI-92 gasoline is needed. It often happens that the fuel grade AI-95 is indicated in the instructions. But experts believe that AI-95 gasoline, which is produced in the Russian Federation, does not meet the quality standard. This fuel contains many anti-knock additives.
To use such gasoline for a chainsaw when creating a mixture is possible only with its high quality. The complexity of the application lies in the use of additives, with the help of which manufacturers increase the operational characteristics of fuel, which has a lower octane rating. Therefore, pouring 95 gasoline is not recommended.
How to choose oil for a chainsaw
Two-stroke chainsaw engine oil should be selected according to more stringent requirements. Experts recommend the use of mineral or semi-synthetic lubricating fluid, which is designed for 2-stroke ICEs used at high speeds.
The advantage of using mineral oil for chainsaws is its low price. Synthetic fluids are more expensive, but have improved quality indicators and comply with European standards.
Synthetic oils can be used in a large temperature difference, they do not create deposits that contain beneficial additives for the motor.
Motor oil is produced by a large number of manufacturers, both foreign and Russian. The best quality oils are those made by Husqvarna. According to some characteristics of branded products, domestic oil of the Lukoil brand is inferior.
Advantages of branded company products:
- economical consumption;
- preservation of quality during prolonged storage or operation in adverse conditions;
- a small amount of toxins;
- lack of soot.
In professional and household saws, oils prepared using American API-TB technology are used. An analogue of these products of Japanese production JASO-FB is also used. Do not use liquid that was created for 4-stroke motors to make a mixture.
The color of the oil, for example green, red, means that the products are produced by some company. When selecting indicators and product characteristics, color is not taken into account. Care must be taken to choose engine oil, the manufacturer and composition of which is unknown.
Before will be obtained additional data on performance and quality of products, the use of this oil is better to give up yet. You can mix together motor oils that have the same characteristics of purpose and composition, which are products of famous brands and are of high quality. Do not mix mineral and synthetic oils.
To prepare a high-quality mixture, you need to use those branded oils or their analogues that are recommended by the operating instructions of the chainsaw. For example, fuels and lubricants of the Husqvarna and Stihl categories can replace each other.
Experts do not recommend the use of lubricant in the gearbox for chainsaws, which is available for 2-stroke engines of mopeds, motor boats. The engines of such devices are used in milder external conditions, due to which they have low requirements for quality indicators.
How to breed gasoline for a chainsaw
Consider how the mixture for a chainsaw is prepared. It is necessary to calculate the correct ratio of gasoline and oil for a chainsaw. For a chainsaw they take fuel with a high octane rating: AI-92 or AI-95.
To prepare the fuel mixture, it is necessary to add 30 g of oil per 1 liter of gasoline, which corresponds to the design of the saw. The resulting fuel fluid is poured into the fuel compartment. Before you dilute gasoline, you should consult a service specialist who specializes in repairing chainsaws.
In order for the saw to have a long service life, it is necessary to properly prepare the gasoline-oil mixture, for which only AI-92 and AI-95 brands can be used. The fuel must not be leaded, otherwise the internal combustion engine may break. You cannot use an old product that has expired, because over time, fuel can change the octane number. The proportion of lubricant and fuel is strictly maintained.
You should not save when choosing oil for chainsaws brand Husqvarna and others. The proportions must be observed due to the fact that excess oil can lead to an increase in soot at the nodes of the chainsaw. Excess gasoline can cause piston damage and engine failure. So, 1 liter of fuel is mixed with 20-50 ml of oil. Husqvarna recommends adding 100 ml of grease to 4 liters of gasoline. This proportion is suitable for saws with power up to 1.5 kW.
For designs 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 as follows: add 100 l of gasoline for chainsaw in 100 ml of oil. Partner recommends diluting the fuel fluid when refueling the chainsaw with the following standards: 100 ml of grease is added to 3.3 liters of fuel.
When using super-synthetic oils, the indicators are 1: 100. That is, the fuel mixture for the chainsaw must be prepared according to the recipe: add 1 ml of lubricant per 1 liter of fuel. When choosing components, you need to use the information that is given in the instructions for any modification of the saw.
Often, plastic bottles and other containers are used to mix the ingredients. With plastic and glass should be careful. When mixing the components, static electricity may appear. 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 must not be stored for more than a month, as materials may oxidize and the composition of the mixture will change.
Damage to the motor, which was caused by fuel expired, acknowledged in the service is not a guarantee. At the same time, the cost of repair 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, remove the remaining mixture.
For best operation of the device it is necessary to make a mixture that will provide smooth operation of the motor, complete combustion of gasoline-oil mixture without the occurrence of soot, smoke or damage.
How to refuel a chainsaw
Consider how to refuel a chainsaw. If the saw is not correctly threaded, this can endanger the life and health of the device operator.
There are rules that must be followed when refueling a saw:
- do not spill oil and fuel mixture;
- the place where the saw will be refueled must be level;
- the place must be removed from the zone where the device will be operated by more than 2 m;
- the site should be located away from fire; no smoking in this place;
- while the fuel tank is filling, you need to fill the oil tank, which is designed to automatically lubricate the chain; You can distinguish containers by special icons;
- before pouring, wipe the neck of the containers with a rag;
- during operation, grease and gasoline must not be spilled, therefore care must be taken when unscrewing the canister lids; when refueling, it is better to use a funnel;
- care should be taken when tightening the lid with the lock;
- experts advise to fill the tank not completely, but leave a little free space.
During operation of a correctly refueled chainsaw, it is necessary to regularly check the tightness of the containers and the operation of the motor. If the chain heats up too much, or gasoline is consumed too quickly (faster than oil), this should cause wariness. Before starting work, a chainsaw is run-in.
With the correct operation of the chainsaw, 1 tank for gasoline should be enough for 30 minutes of operation of the device with maximum load. When gasoline runs out, the lubricant in the second tank still remains, but in small quantities.
The mixture must be prepared in the amount necessary for the implementation of a small amount of work, since with prolonged storage of the solution its quality characteristics deteriorate. The prepared mixture must be spent within a few days.
A fuel mixture that has been stored for about a month reduces engine performance. Resinous substances are formed in the nodes, and soot appears, piston rings lose their mobility. The longest shelf life of the mixture is no more than 2 weeks. During this period, the solution will not lose its quality. If the air temperature is more than 25ºC, then the shelf life of the product is reduced to 10 days.
Some experts allow the use of an expired mixture to save. To do this, you can spend it gradually, gradually mixing in a fresh solution in a volume of not more than 10% of the total amount of the mixture. The finished gasoline-oil mixture must be filtered.
If you follow all of the above recommendations, you can ensure reliable operation of the chainsaw. Also, when performing work, safety precautions must be observed, since the chainsaw operates using a chain that rotates at high speeds and, if the operating rules are violated, can be dangerous for the worker himself and those around him.
Preparation of the fuel mixture: the proportion of oil and gasoline for a chainsaw
The chainsaw engine is the "heart" of the tool, so it is very important to use a properly prepared fuel mixture.
The fuel mixture for the chainsaw is prepared from two components. oil and gasoline. Chainsaws are equipped with two-stroke engines, so the oil is not added to the lubrication system (like a four-stroke engine), but directly to gasoline. In this case, it is very important to observe the correct proportions of the ingredients, of course, in no case try to work on clean gasoline, because in this way you will very quickly “kill” the chainsaw.
If we talk about which gasoline to be poured into a chainsaw, it will optimally use fuel with an A-95 octane rating, in this case, fuel savings can turn out deplorably. Often, European manufacturers indicate that you can use A-90 or A-92 gasoline, but in post-Soviet countries the quality of gasoline is inferior to European, so in our realities it is better to use better gasoline.
As for the proportion of the benzo-oil mixture, then everything is simple: you must follow the instructions for the tool. All manufacturers of chainsaws indicate the required ratio in the instruction manual or in the instrument passport, in addition, the proportions for refueling the chainsaw may differ depending on the model of the chainsaw. As a rule, the proportion of oil and gasoline to the chainsaw of famous manufacturers is a ratio of 1:40 or 1:50, which means 1 part of oil for, for example, 40 parts of gasoline. Now the arithmetic of 1 liter of gasoline = 1000 ml of gasoline, divide by 40 and get 25 ml of oil. If you perform the same actions to a ratio of 1:50, then we get 20 ml of oil per 1 liter of gasoline. As for budget-made chainsaws made in China, the situation is slightly different. The ratio of gasoline to oil for chainsaw made in China 1:25, that is, 1000 ml of gasoline divided by 25, we get 40 ml of oil. The thing is that in branded chainsaws a good assembly and the distance between the pistons and cylinders in the engine is much smaller than that of Chinese chainsaws, therefore the required amount of oil differs almost twice.
In order to measure the correct portion of oil, use an ordinary medical syringe of sufficient volume.
Another subtlety. pour gasoline into a dry canister for gasoline, and then oil. The procedure, on the contrary, is fraught with a poor quality fuel mixture, because the oil is more dense, sticks to the bottom of the canister. what a good mix.
Be sure to prepare the fuel mixture in a canister and pour ready-made special fuel into the gas tank! Never cook or mix directly in the fuel tank of a chainsaw!
If you figured out how to breed gasoline for a chainsaw, then a few words should be said about the storage conditions and shelf life of the fuel mixture. It’s best and easiest to cook a 1-liter gasoline-oil mixture, it is recommended to do this immediately before working with the tool. The fuel tanks of chainsaws have a volume of 0.3 to 1 liter. In domestic use, in one session, the entire volume of the prepared combustible mixture is rarely used, so the remainder can be saved until the next session. It is necessary to store the fuel mixture in a special canister for gasoline, in a dry, dark place. It is optimal to expect that the shelf life of the finished mixture will be 7-10 days. The fact is that the oil currently on the market is not synthetic, but organic, that is, natural. After 10 days, all lubricating properties are lost, gasoline simply “eats” the oil. Naturally, it is no longer possible to use such fuel, this can cause breakdown and failure of the chainsaw.
At the end of the work, it is necessary to drain the fuel mixture, start the chainsaw, the tool will stall (so that the saw has a dry carburetor) and now you can leave it until the next operation session.
Unsuitable fuel mixture must be disposed of.
