How to dilute gasoline for a chainsaw partner

Gasoline for chainsaw

For domestic chainsaws (Ural, Druzhba, etc.), AI-80 gasoline is used. Oils can be used domestic, such as M8-V (or early marking AS-8.10), M-12 TP, M-12TPU, MGD-14M. It is also possible to use oils from foreign manufacturers.

In any case, the proportions when mixing oil and gasoline should be 1/25, that is, one hundred grams per two and a half liters of gasoline.
For modern chainsaws from foreign manufacturers, the proportions are usually equal to 1/40 (100 grams per 4 liters of AI-92), 1/50 (100 grams per 5 liters of AI-92).

Use AI-92 gasoline. You can often see that the AI-95 brand will be indicated in the instructions. but with our quality of this gasoline, the octane number of which is catching up with additives, I would not recommend using the 95th if you are not sure of its quality.

about mixing proportions:


To measure the required amount of oil, you can use a syringe, a measuring bottle, a special dispenser or, for example, a bottle with a dispenser from Stihl.
Oils from different manufacturers in different colors. As you can see in the picture above, HP calm oil (mineral water) is red, more expensive synthetic ones are green. Husqvarna oil can be green or blue.


[important] Tips: It is better to overfill the oil than underfill! If it is written 1/50, then when you pour 25 grams per liter, terrible will not happen, since coking in this case is unlikely. But if you add 15 grams per liter, it is quite possible that this will not be enough. Do not store the ready-made fuel mixture for more than a month (preferably less), as it loses its octane number (gasoline “fizzles out”). Run out the entire tank or drain before the season to avoid loss of gasoline quality and wear of rubber and plastic seals.

Never use oils for mopeds. they are designed for lower rpm [/ important]

Features of the preparation of the mixture

For safety reasons, it is recommended to prepare the fuel mixture in a metal canister that is not subject to the formation of static electricity.

  • The recommended proportions of gasoline and oil for each model are individual. In most cases, this is a ratio of 50: 1 and 40: 1. Chainsaws running on a gasoline-oil mixture in a ratio of 25: 1 are much less common.
  • According to the manufacturers of branded chainsaw equipment, their products do not need running-in. Nevertheless, during the first hours of operation, experts advise to operate a new chainsaw on a fuel mixture with an increased m of oil and, if possible, in a gentle mode.

For preparation of the working mixture, containers with built-in dispensers are convenient. The selectivity of fuel filters at gas stations, in some cases, leaves much to be desired, therefore, it is recommended to filter gasoline through suede or non-fiber material.

The implementation of these recommendations will save you from spontaneous equipment failures associated with a malfunction of the carburetor.

The specific characteristics of mineral or organic chain oil are focused on the lubrication and cooling of the saw set, therefore not suitable for preparing a fuel mixture.

Incorrect operation of any tool not only significantly shortens its service life, but also makes it potentially traumatic. This is especially true for devices with the highest injury risk at the beginning, to which the chainsaw belongs.

The operation of the tool always begins with its preparation for work. What kind of gasoline should be poured into the chainsaw. Green tint oil is premium. What kind of gasoline do you need so what kind of gasoline do you put in your chainsaw? Husqvarna, Partner.

What kind of gasoline so what kind of gasoline should you put into your chainsaw? Therefore, pour pure gasoline into. In the case of a chainsaw, this is first refueling.

And although refueling a chainsaw itself is not a super-complicated operation, its incorrect or careless execution can become a prerequisite for a severe threat of tool breakage and injury to the person working with it.

Why oil does not flow to the chainsaw chain?

In the event that the oil does not go to the chainsaw chain at all, it means that either the oil pump drive itself has failed, or there are problems with air leaks.

  • Breakdown of the oil pump. If, when the oil pump plunger adjustment screw is unscrewed, oil is still not supplied to the chainsaw chain, then the drive, which is a plastic ring with grooves, has broken. Over time, the grooves can wear out, and the drive will fail, after which it will simply have to be replaced.
  • The hose that supplies pressurized oil to the chain is loose or worn out. You need to re-attach it to the fitting or replace it.
  • The grooves along which the oil is supplied to the chainsaw chain are clogged. this is the most common occurrence. They need to be cleaned, after which the feed will resume.

    What gasoline to fill?

    The manual for Husqvarna chainsaws says that you can refuel with gasoline with an octane rating of 90. However, we recommend using AI-92 gasoline. Why 92? Esters are used in AI-95 and AI-98 gasoline as anti-knock additives to increase the octane number.

    And AI-95 is generally AI-92 with 5% methyltrebutyl ether (antiknock additive).

    Increased in gasoline additives (low-quality) to increase the octane number leads to the appearance of rust on the electrodes of the spark plugs, carburetor jets and “poisoning” of the catalyst, which in turn leads to an increase in fuel consumption.

    While AI-92 is a mixture of 92% isooctane and 8% n-heptane. The octane number of isooctane is 100 (it does not give detonation), but n-heptane, on the contrary, provokes detonation, its octane number is 0. AI-92 is ideal for refueling your chainsaw.

    Fuel mixture preparation

    In fact, all engines of the chainsaws available now are two-stroke.

    In practice, this means that for their normal and non-hazardous work, they do not need clean gasoline, but a fuel mixture of gasoline with the addition of engine oil in a certain proportion to it.

    This is a feature of all two-stroke engines: they are lubricated during operation with oil entering the cylinders simultaneously with the supply of gasoline.

    The optimal ratio of engine oil and gasoline in a mixture for a chainsaw is considered to be 1:50.

    Usually the octane number of gasoline preferred for optimal engine performance and the recommended brand of oil are indicated by the manufacturer of the chainsaw in the operating manual attached to it.

    The same manual also indicates the optimal ratio of engine oil and gasoline, and this ratio is not static and, depending on the type of oil, varies in the range from 1:25 to 1: 100.

    But in the overwhelming majority of cases, a ratio of 1:50 is used, and quite often this ratio is used when there is no operating manual (for example, when buying a used chainsaw).

    But such actions still cannot be considered fully justified. The engine of a modern chainsaw can operate at a maximum speed of 13.5 thousand per minute, which leaves no room for experiments with its lubrication. What gasoline to pour into the chainsaw, the oils used are painted into the tank.

    What kind of gasoline to pour into the chainsaw. from calm to. Components for preparing a fuel mixture which gasoline to pour into chainsaws. how many.

    The only thing that is justified to allow, when preparing a fuel mixture for a used chainsaw, in which the engine is already very worn out, is to increase the initially recommended amount of engine oil added to gasoline by 5-6%.

    To sentence the fuel mixture, it is advisable to use a special container with marks on the body.

    Ratio numbers indicate the number of parts of gasoline per 1 part of oil. If we translate the ratio 1:50 into a more familiar system of measures, then this means that 1 liter of gasoline needs 20 ml of oil.

    Hello! Tell me what kind of gasoline can be poured into a modern chainsaw. What gasoline to pour into a chainsaw.

    The fuel mixture is prepared in accordance with the specified proportions in a certain sequence.

    First, oil is completely poured into the iron container, then half of the required volume of gasoline is added to it. It is not recommended to use plastic canisters or plastic bottles for this, as their material can react with gasoline, quickly oxidizing.

    On the Stihl chainsaw, what gasoline should I fill with 92 or 95? In gasoline in the tank you need to fill it with a chainsaw for.

    Then the poured oil and gasoline are thoroughly mixed until a uniform color of the mixture is obtained, only then the second half of the gasoline is added, bringing its amount to the required volume.

    The proportions of oil and gasoline for a chainsaw: what to use, the ratio, how to fill, dilute

    The chainsaw is started by an engine running on a mixture of gasoline and oil adapted to the ambient conditions.

    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 at high engine speeds.

    Therefore, increased requirements are imposed on the quality of lubricants and fuel.

    For imported chainsaws, the following oils are recommended:

    • classification of TA, TB and TC (TSC-1/2/3) according to American API standard.
    • 2t oil for chainsaws of the Japanese JASO standard, corresponding to classes FA, FB and FC;
    • oil of the European standard ISO, class EGB and EGC.

    As for domestic chainsaws, high-quality oil is also recommended for them.

    If it is not possible to purchase it, then you can use a lubricant intended for 2-stroke motorcycle engines.

    What gasoline should you use for your chainsaw? How to breed it correctly?

    The chainsaw is simple to operate and is sometimes needed in a private household. The device cannot fully function if you do not use the correct fuel mixture, which you should be able to prepare.

    Fuel selection

    Which fuel to choose for a chainsaw is a non-idle question, the success of the unit directly depends on it. According to existing canons, good gasoline for a chainsaw is considered not leaded, but high-octane from a trusted manufacturer. The cleaner the fuel, the better. If gasoline has been stored in a canister for a year or a year and a half, this will adversely affect the nature of the device’s operation, therefore, the substance should be prepared before starting work.

    It is important to monitor that there is no alcohol in the fuel, any additives that can disrupt the functioning of the power plant. Experts are still debating which is better than 95 or 92. The first has more stable detonation indicators, but most often the 92nd is still used. The reason is simple: questions often arise by the 95th, it contains a large number of various additives that have a bad effect on the operation of the saw engine. Micro-knock occurs (piston impulse in the opposite direction), which occurs practically at every revolution of the crankshaft. If the octane number is even higher (98), then the micro impacts will become even more intense.

    The consequences of improper gasoline on the quality of the unit can only be negative:

    • The mechanism will be difficult to start.
    • The power will be minimal.
    • Parts will wear more intensively.

    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 the Stihl chainsaw only requires gear oil. 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.
    • 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 rather quickly. At room temperature, flammable liquid deteriorates within two weeks.

    The highest quality product is considered to be the product of Husqvarna, followed by Lukoil machine oil.

    The advantages of these oils:

    • Low consumption.
    • Maintaining quality.
    • Ability to maintain technological qualities for a long time.
    • Can work in extreme conditions.
    • No toxins.
    • Minimum amount of carbon deposits.

    Many professional tools use a lubricant made using API-TB technology (USA). Products made according to the JASO-FB method (Japan) are also popular.

    It is permissible to mix oils from different brand manufacturers with similar characteristics. Mineral and synthetic oils are incompatible. The best oil for household chainsaws is considered “Standard”, for professional equipment the technical fluid “Ultra” is optimal.

    Some oils can successfully replace each other. For example, substances produced by Husqvarna and Stihl. Lubrication for scooter engines or motor boats is not suitable for chainsaws, the oil quality in them is low. If the proportions of oil and gasoline are not maintained, then the tool will quickly fail due to the abundant formation of carbon deposits.

    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.

    If we take, for example, a 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 a 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 will be required.

    How to dilute engine oil and gasoline, in what proportions? This question arises for all users. First you need to stock up on containers:

    • Measuring liter bottle
    • Dispenser and syringe
    • A watering can, which will allow you to pour the substance into the tank

    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.

    Chainsaw device

    Each chainsaw has different technical data and can do different work.

    Powerful saws are suitable for felling centuries-old trees, small-format chainsaws are more suitable for various tasks in the home garden:

    • Cutting tree branches
    • Harvesting firewood

    Chainsaw standard blocks:

    • Power point.
    • Clutch.
    • Ignition unit.
    • Carburetor.
    • Fuel block (oil and fuel tank).
    • Filters for cleaning incoming air.
    • Starter.
    • Chain.
    • Tire.
    • Chain brake.
    • Tension mechanism.
    • Chain lubrication element.

    Each chainsaw requires high-quality fuels and lubricants, it is they that ensure long-term productive operation of the unit. What gasoline for the chainsaw to fill, in what proportions?

    For domestic chainsaws, simple oils are suitable, foreign chainsaws need more complex fuel mixtures that have been thoroughly cleaned.


    Tips and life hacks are extremely useful in practical work, consider some of them:

    • It is convenient to use canisters with dispensers, while experienced people filter gasoline through suede. The cleaner the fuel, the better the carburetor will work.
    • Gasoline can actively evaporate, especially at high temperatures, a suspension falls out at the bottom of the canister, which cannot be poured into the engine.
    • It is recommended to prepare fuel for no more than three operational fillings.
    • The quality of the fuel can be affected by the material of the container, especially PVC materials react actively.
    • If the combustible mixture is poured of poor quality, the chainsaw may be removed from the warranty.
    • During operation, it is necessary to test the tightness of containers and the rhythmic operation of the engine.
    • One of the first signs of a malfunction is undue heating of the circuit.
    • Before subjecting the tool to severe stress, it should be tested at idle speed.
    • The tank is enough when working for half an hour.
    • There is still grease (residues) in the second container when it has run out in the tank.
    • If a large amount of smoke is generated during operation, this means that the fuel is of poor quality.
    • During the operation of the unit, do not approach an open fire.
    • (distance up to 2 meters).
    • Fuel should not be poured “under the rim”, leave a little space.
