How much oil needs to be poured into the chainsaw

Why gasoline is mixed with oil for refueling chainsaws

It is necessary to dilute gasoline with oil in order to avoid the failure of the internal combustion engine. The reason for this is the design features of the lubrication system for two-stroke motors. In the design of such engines there is no chamber for filling engine oil, and if you fill in fuel without lubricant, then the crankshaft, piston, bearings and connecting rods will not receive lubrication. This will significantly reduce the service life of all the listed parts, therefore, it is prohibited to fill in clean fuel.

Gasoline and oil for the chainsaw must be poured in the appropriate proportions, which makes it possible to effectively lubricate the 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, from the first day of operation of the tool, it is necessary to fill it not only with high-quality materials, but also observe the correct proportions.

For the engine to work properly, the main thing is to fill it with clean fuel without contamination.

What gasoline to pour into a chainsaw

Let’s find out what kind of fuel is recommended for this type of device. Since there is a 2t (two-stroke) engine on chainsaws, and an oil pump cannot be installed on it, it is forbidden to use pure gasoline for the saw. A fuel mixture of fuel and oil is poured into the saws. The norms for refueling chainsaws of different models are regulated by the manufacturer.

Consider what kind of gasoline to pour into the chainsaw experts advise. Refueling the chainsaw is carried out with a fuel with an octane number of more than 92. To create a mixture, you must not use fuel with an expired shelf life, made from condensate, which includes water and various impurities.

Domestic saws run on AI-80 fuel. For foreign modifications, AI-92 gasoline is needed. It often happens that the instructions indicate the grade of AI-95 fuel. 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.

It is possible to use such gasoline for a chainsaw when creating a mixture only with its high quality. The complexity of the application lies in the use of additives, with the help of which manufacturers increase the performance characteristics of a fuel that has a lower octane number. Therefore, it is not recommended to fill in 95 gasoline.

How to choose your chainsaw oil

Oil for two-stroke chainsaw engines should be selected for more stringent requirements. Experts recommend using a mineral or semi-synthetic lubricating fluid, which is designed for 2-stroke internal combustion engines used at high speeds.

much, poured, chainsaw

The advantage of using mineral oil for chainsaws is its low price. Synthetic fluids are more expensive, but have improved quality indicators and meet European standards.

Synthetic oils can be used with a large temperature difference, they do not create carbon deposits, they contain additives useful for engine operation.

Motor oil is produced by a large number of manufacturers, both foreign and Russian. The best quality oils are made by Husqvarna. According to some characteristics of branded products, domestic oil of the Lukoil brand is inferior.

Benefits of branded products:

  • economical consumption;
  • preservation of quality during prolonged storage or operation in adverse conditions;
  • a small amount of toxins;
  • no carbon deposits.

In professional and household saws, oils prepared according to the American API-TB technology are used. An analogue of this Japanese-made JASO-FB product is also used. Liquid, which was created for 4-stroke engines, cannot be used to make a mixture.

The color of the oil, for example, green, red, indicates that the product is manufactured by a certain company. When selecting indicators and characteristics of a product, color is not taken into account. Carefully choose engine oil, the manufacturer and composition of which is unknown.

Until further data on performance and product quality is obtained, it is best not to use this oil for now. You can mix motor oils with each other, which have the same characteristics of purpose and composition, which are products of famous brands and are of high quality. Mineral and synthetic oils must not be mixed.

To prepare a high-quality mixture, it is necessary to use those branded oils or their analogues, which are recommended by the instruction manual for the chainsaw. For example, fuels and lubricants of the Husqvarna and STIHL categories can be substituted for each other.

Experts do not advise using grease in the gearbox for chainsaws, which is produced for 2-stroke engines of mopeds and motor boats. The motors of such devices are used in milder external conditions, due to which they have low requirements for quality indicators.

Gasoline and oil for chainsaws. which is better

Often beginners ask, which one is better to take gasoline for their instrument? In order not to make a mistake in the choice, it is recommended to read the instructions for the tool. In the instructions, each manufacturer indicates the corresponding brand of fuel. If the manufacturer indicates that the octane number should not be lower than 95, then it is not recommended to pour 92 gasoline.

Motor oils for two-stroke engines are produced by the following manufacturers:

How to Add Bar and Chain Oil to Your Gas Chainsaw

Usually, the ratio is indicated on the lubricant bottle, so it will be difficult even for beginners to get confused with the preparation of the fuel mixture. Do not under any pretext use the working off even as a chain lubricant. This will lead to the fact that soon it will be necessary to repair the tool.

Gasoline to chainsaw oil ratio

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 sawers. It is this ratio for preparing the fuel mixture that is close to ideal, and provides lubrication of the rubbing parts of the crank mechanism and the piston.

How much oil should be poured into gasoline in milliliters? Calculated per ml, the proportion of oil and gasoline 1 to 50 is 20 ml per 1 liter. To prepare the correct mixture, you should fill 1 liter of gasoline in 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 up to the appropriate mark. If you plan to immediately prepare 2 liters of fuel, then 40 ml of lubricant must be added to this amount of gasoline.

There are other ratios that different manufacturers offer. These values ​​of the ratios differ insignificantly, but if you have subtracted other values ​​in the instrument’s passport, then you need to adhere to them. A value of 1 in 50 or 40 is standardized. Pour 15 ml of oil into 1 liter of fuel in the summer, and in winter, add at least 20-25 ml. Knowing the recipe for preparing the mixture, you should also figure out what kind of gasoline to pour into the chainsaw?

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 Husqvarna chainsaws 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 grease 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 when refueling the chainsaw with fuel, 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 need to use the information that is given in the instructions for any modification of the saw.

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 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, 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 motor, complete combustion of the gasoline-oil mixture without the formation of carbon deposits, smoke or damage.

Let’s start with the engine

Engine care includes blowing out the cylinder cooling fins, checking the spark plug, oil, fuel and air filters.

The air filter and cylinder cover must be removed to clean the cylinder fins. When refitting the cylinder cover, check that the wires of the switch and the sealing ring are in the correct position.

To clean the fuel and oil filters, you need to remove them and rinse them with gasoline for chainsaws, or replace with a new filter.

It does not hurt to check the spark plug periodically. In case of contamination, clean the electrodes with a wire brush and restore the gap to 0.65 mm.

To check the air filter, we take it out, remove the dust from the surface. If it is heavily clogged, then it is better to rinse it in gasoline.

If cleaning with compressed air, direct the jet towards the inner surface.

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.

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 Hurstavna chainsaw, but only transmission oil is required for the STIHL chainsaw. 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:

  • Solar radiation intensity.
  • 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 oils should not change dramatically with a difference in temperature conditions.

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:

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, flammable liquid deteriorates within two weeks.

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 the 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 the 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.

Chainsaw Oil to Gasoline Ratio

Regardless of the type of chainsaw, such a tool is powered by a two-stroke engine. It runs on a mixture of special oil and gasoline. However, not every user of the equipment knows in what ratio these elements should be mixed, how to properly store the prepared mixture, etc. As a result, many problems can arise during operation, especially if a person did not correctly carry out all the listed manipulations.

Therefore, for stable and long-term operation, it is necessary to ensure the optimal ratio of oil and gasoline for the chainsaw. At the same time, due to the high loads and different operating conditions of the equipment, special attention should be paid to the quality of both fluids.

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.

What gasoline to use

Various types of fuels can be found at gas stations. Each of them has its own cost and technical characteristics, including special additives in gasoline. However, not every brand is suitable for a chainsaw. In order not to spoil the equipment and ensure optimal operation, it is necessary to fill fuel above 92. Some experts note that due to the poor quality of Russian fuels and lubricants, instead of 92, 95 should be used.

Another rule for the proportion of oil and gasoline for a chainsaw is related to leaded fuel. It is strictly forbidden to choose this type of fuel, as it increases the failure of the engine and its components.

What happens if you pour working off 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 working off with gasoline. The reasons for this are the following factors:

  • Other viscosity of the material, therefore, mining is not able to provide effective lubrication of rubbing parts and mechanisms
  • The mining contains small particles of metal and shavings, which, getting into the tank, will cause clogging of the fuel filter and channel. If the grease enters the cylinder together with small particles, they will leave their imprint in the form of accelerated wear of the piston rings.
  • Emitting a lot of black smoke, which indicates burning of oil

It is impossible to pour surrogate materials not only into the gasoline tank, but also into the chain lubrication tank. What happens if you use the development in the tank for chain lubrication can be seen in the video.

Using the instructions, you can independently prepare the correct fuel mixture on which the chainsaw will work. If the fuel mixture is diluted incorrectly, not only will the tool life be reduced, but also its performance will decrease.

Household and professional chainsaws are powered by two-stroke internal combustion engines operating on a metered 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-cube power unit makes it necessary to operate chainsaw engines at high-speed modes, therefore, increased requirements are imposed on the quality of both components of the fuel mixture.

Caution. counterfeit!

Small private companies from China and other Asian countries specialize in the production of motor oils, which are sold at a lower cost in the markets under the trademarks of leading manufacturers.

  • The characteristics of counterfeit products are an order of magnitude lower than those of the branded originals. The constant use of counterfeit products adversely affects the operation of the chainsaw and the durability of its operation.
  • Only an experienced specialist can determine the status and quality of oil, therefore, you can avoid possible risks by buying consumable components in a network of branded and licensed retail outlets.
  • The use of substandard lubricants for service specialists is a legal basis for depriving the owner of a faulty saw of warranty repair and restoration obligations.

Chainsaw refueling instructions

Knowing the ratio of the preparation of the petrol-oil mixture, you can start refueling it. Refueling instructions are as follows:

  • First you need to prepare the mixture. Having combined the two main components, you should mix them thoroughly.
  • Place the tool on a clean and level surface. Before unscrewing the gas tank cap, it is necessary to clean or blow off sawdust, dust and dirt.
  • The filler neck must point upwards.
  • Install a small watering can in the neck, then pour fuel
  • Control the refueling process, as the volume of the tank is small, so it fills up quickly
  • Do not fill up to the full maximum, since when the tank cap is closed, the remaining fuel will splash out.
  • After the fuel is poured into the tank, immediately add chain lubricant.
  • Fuel consumption and chain lubrication are approximately the same, therefore both tanks must be filled at the same time.
  • After refueling, you can start starting the engine.

It is better to start the engine not in the place where the refueling was carried out, but to move to a distance of 2-3 m. The tool is ready for work, and you can start to start it. How the chainsaw engine starts, you can read in this material (link).

Chain saw oil

  • Mineral
  • Synthetic

Experts advise using synthetic chainsaw oil, but it is always more expensive at a price. The main advantage of this type of lubricant is that during the operation of the equipment, carbon deposits do not form in the cylinder, and this prolongs the service life of the equipment.

If mineral oil has been used for 100 working hours, then it is better to continue using it, since carbon deposits could accumulate during operation. A synthetic product has the ability to cleanse and wash away the deposited layer from the cylinder walls, and this will damage the equipment.

Gasoline to chainsaw oil ratio

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 sawers. It is this ratio for preparing the fuel mixture that is close to ideal, and provides lubrication of the rubbing parts of the crank mechanism and the piston.

How much oil should be poured into gasoline in milliliters? Calculated per ml, the proportion of oil and gasoline 1 to 50 is 20 ml per 1 liter. To prepare the correct mixture, you should fill 1 liter of gasoline in 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 up to the appropriate mark. If you plan to immediately prepare 2 liters of fuel, then 40 ml of lubricant must be added to this amount of gasoline.

There are other ratios that different manufacturers offer. These values ​​of the ratios differ insignificantly, but if you have subtracted other values ​​in the instrument’s passport, then you need to adhere to them. A value of 1 in 50 or 40 is standardized. Pour 15 ml of oil into 1 liter of fuel in the summer, and in winter, add at least 20-25 ml. Knowing the recipe for preparing the mixture, you should also figure out what kind of gasoline to pour into the chainsaw?

Features of preparation and storage of the fuel mixture

Safety regulations prescribe to dilute gasoline and oil in a metal canister. This eliminates the risk of static electricity and fuel ignition.

Experts advise to pour oil into an incomplete container, mix thoroughly, and then top up with clean gasoline to the specified level. Saving working time by preparing the working mixture directly in the gas tank of the chainsaw should be excluded from everyday practice.

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 flushing.

Petrol

The main component of the fuel mixture for chainsaw engines is gasoline with an octane number of at least 92. Consumables with expired storage, made on the basis of gas condensate, which have water and mechanical impurities in their volume, are not suitable for the preparation of fuel.

  • The opinions of experts on the use of gasoline of different brands are ambiguous. On the one hand, the incomplete compliance of domestic gasoline A-92 with European standards is recognized.
  • On the other hand, the quality of A-95 gasoline is questioned due to the high content of anti-knock additives. It is possible to use this fuel for the preparation of fuel for a chainsaw 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 performance properties of motor gasoline with a lower octane index.

Also, irreversible changes in the working properties of the fuel occur when it is stored for a sufficiently long time in a plastic container, regardless of the level of its petrol and oil resistance.
