Oil For Two-Stroke Engines Of Chainsaws Proportions

A wide range allows you to choose oil that fully corresponds to the class and characteristics of the chainsaw, the conditions of its subsequent operation.

  • For budget models you can use oils of the Standard category, for professional chainsaws. Consumables of the Super and Ultra categories are recommended.
  • To prepare a full-fledged fuel mixture for a chainsaw, it is advisable to use branded oils or their branded counterparts recommended by the instruction manual. In particular, Stihl and Husqvarna engine oils are completely interchangeable in composition and application.

Experts recommend that owners of chainsaws exclude from the scope of attention motor oils intended for two-stroke engines of mopeds, boat motors and other mechanized household appliances.

The power units of this equipment operate in more comfortable conditions, which makes the requirements for their operational characteristics less stringent.

Measuring containers

To maintain the correct proportion of gasoline and oil, the calculation table printed on the saw body can be used. Branded containers of leading manufacturers of engine oils are equipped with built-in measuring devices that ensure accurate dosage of oil for different volumes of fuel mixture.

Volumetric utensils are included in the factory set of many models of budget chainsaws. In SEPARATE cases, dilute gasoline with oil in a given proportion will help a medical syringe with a volume of 20 cm3.

Features of running in a new tool

This concept includes the gentle operation of the chainsaw at the initial stage of its operation. The technology also provides for the operation of the engine on a mixture with an engine oil increased by 20%.

The running-in time in engine hours is indicated in the attached instructions. In practice, for the tool to reach the working level, it is enough to generate 3-5 refills of the saw’s gas tank.

New models do NOT need running-in, but the first hours of operation are not recommended for the chainsaw to be used with heavy loads.

Saw refueling algorithm

The gasoline / oil mixture is best prepared in a 2.5 liter plastic bottle if you have to refuel the tool frequently. If you need to prepare fuel for just a few fillings, then it is better to use a smaller container. It is imperative that you purchase measuring containers, this will allow you to maintain the exact proportions of both liquids. Most oil manufacturers offer such measuring devices.

Initially, fuel is poured into the container, and then oil is added. It is imperative to take into account that there must be enough space in the container to thoroughly mix the fuel mixture.

After preparation, it is recommended to store this mixture NOT more than 2 weeks. It is recommended to shake the mixture thoroughly with each refueling. If you are NOT sure that all the fuel will be used up, then it is better not to prepare it in large quantities.

The proportions of gasoline and oil for chainsaws: features of the preparation of the fuel mixture

The fact that it is prohibited to pour “clean” gasoline into chainsaws is warned by sellers of buyers at the time of purchasing the tool. Many buyers find out about this for the first time, wondering why it is necessary to dilute gasoline with oil. If you neglect this rule, then the consequences for the tool can be simply catastrophic. In most cases, even an overhaul of the engine will no longer be able to help. In the material We will find out what proportions of gasoline and oil should be for refueling a chainsaw, and also what may be the risk of non-compliance with this rule.

What will happen 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 capable of providing 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 along with small particles, they will leave their mark in the form of accelerated wear of the piston rings.
  • Generation of a large amount of black smoke, which indicates burning oil

Filling in surrogate materials It is impossible not only to the gasoline tank, but also to the chain lubrication tank. What happens if you use the working out in the chain lubrication tank can be seen on.

Using the instructions, you can independently prepare the correct fuel mixture on which the chainsaw will work. Improper dilution of the fuel mixture will not only reduce tool life, but also reduce tool performance.

The proportion of oil and gasoline for a chainsaw: how to dilute

All modern chainsaws are equipped with a two-stroke engine. Its long and trouble-free operation directly depends on whether the proportion of oil and gasoline is correct for the chainsaw. The variety of tool brands and the features of each of them are a prerequisite for the fact that this procedure is not easy for most novice users of chainsaws.

Step by step instructions for refueling

If you want to refuel your chainsaw, you need to follow a simple algorithm:

Instructions for refueling a chainsaw

Knowing the ratio of the preparation of the petrol-oil mixture, you can start refueling it. The refueling instruction is as follows:

  • First you need to prepare the mixture. Having combined the two main components, you should mix them thoroughly
  • Tool Place on a clean and level surface. Before unscrewing the gas cap, it is necessary to clean or blow off sawdust, dust and dirt
  • Tank neck must point up
  • Install a small watering can in the neck, then pour fuel
  • I control the filling process, since 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 motor 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. You can read how the chainsaw engine starts in this material (link).

Storage advice

The mixture is better prepared in an amount that should be enough for 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 for a few next days.

A mixture of gasoline with a month-old oil impairs the traction capabilities of the engine. There is also the formation of resinous compounds in the fuel system and intense carbon formation in the combustion chamber, loss of mobility of the piston rings.

  • With minimal damage to quality, it is advisable to store gasoline with oil for NOT more than 2 weeks. At an ambient temperature of 25 degrees or more, this period is reduced to 8-10 days.
  • In order to save money, the expired mixture can be gradually consumed by mixing it into the 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 for non-fiber material such as suede, or fine-mesh twill weaving, metal mesh.

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 brand name of leading manufacturers.

  • The characteristics of counterfeit products are an order of magnitude lower than the original ones. 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 the oil, so 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.

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 the 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 get advice from service specialists, 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 NOT leaded, otherwise the internal combustion engine may break. 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 provoke piston damage and engine breakdown. 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, dilute the gasoline like this: add 5 liters of gasoline for a chainsaw to 100 ml of oil. Partner recommends when refueling a chainsaw with fuel, dilute the fuel fluid at the following rates: add 100 ml of lubricant 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 100 ml of lubricating fluid 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.

Often plastic bottles and other containers are used to mix ingredients. Be careful with plastic and glass. Mixing the components may generate static electricity. It is necessary to ensure that no pebbles, sand or drops of water get into 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 the 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 engine, complete combustion of the gasoline-oil mixture without the formation of carbon deposits, smoke or damage.

Recommended oils for refueling chainsaw:

  • STIHL HP. specially developed for chainsaw engines. Perfectly proven in all weather conditions, 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 of 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. multigrade oil for budget models of chainsaws, intended for use at temperatures from 20 to 40C 0.

What gasoline to pour into a chainsaw

Let’s find out what 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. The saws are filled with a fuel mixture of fuel and oil. 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 rating of more than 92. To create a mixture, you cannot 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 95 gasoline.

It is better to start the motor 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. You can read how the chainsaw engine starts in this material (link).

The ratio of gasoline to chainsaw oil

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 sawflies. 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 put 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 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, which are offered by different manufacturers. These values ​​of the ratios differ insignificantly, but if you subtracted other values ​​in the passport for the instrument, 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 topping up 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 choose your chainsaw oil

Oil for two-stroke chainsaw engines should be chosen according to 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.

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.

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 Lukoil oil 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 that 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 company. When selecting indicators and characteristics of the product, Color is not taken into account. Carefully choose engine oil, the manufacturer and composition of which is unknown.

In addition to obtaining additional data on performance and product quality, it is better to refuse 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 branded oils or their analogues, which are recommended by the instruction manual for the chainsaw. So, for example, fuels and lubricants of the Husqvarna and Stihl categories can replace 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.

Features of running in a new tool

This concept includes the gentle operation of the chainsaw at the initial stage of its operation. The technology also provides for the operation of the engine on a mixture with an engine oil increased by 20%.

The running-in time in engine hours is indicated in the attached instructions. In practice, for the tool to reach the working level, it is enough to generate 3-5 refills of the saw’s gas tank.

New models do NOT need running-in, but the first hours of operation are not recommended for the chainsaw to be used with heavy loads.
