High-quality refueling of a chainsaw with fuels and lubricants determines its traction characteristics and durability of operation. Information about what kind of gasoline to fill in a chainsaw is available in the attached instructions, but there is practically no information about the nuances of choosing consumables in the description.
The design feature of the power units of chainsaw equipment is, first of all:
- the ability to work for a long time at high-speed operating modes;
- compact dimensions;
- small displacement and high compression ratio.
These characteristics impose special requirements on the choice and quality of fuels and lubricants.
The operational characteristics of the saw, in particular, the consumption of gasoline per hour, engine thrust and low-cost development of the overhaul life of the tool are largely determined by the competent adjustment of the carburetor and the correct selection of the components of the fuel mixture.
Recommendations for choosing gasoline
By current standards, the best chainsaw gasoline should be unleaded, high octane, and fairly fresh. A high degree of purification from foreign impurities is welcome.
- Refueling the fuel system with fuel more than six months old has a negative effect on the traction characteristics of the internal combustion engine, contributes to carbon formation and the occurrence of detonation phenomena.
- It is advisable for novice and experienced users to exclude low-octane gasoline for chainsaws, as well as cheap, unknown engine oils, from their scope. The use of leaded fuel is not prohibited, but in order to extend the life of the saw, it is best to refuse to use it at the selection stage.
Practice shows that saving on the quality and cost of consumables adversely affects the performance of chainsaw equipment and the duration of its full operation.
Fuel problems
Problems associated with the flow and combustion of fuel in the cylinder are most often associated with improper operation of the carburetor. Typically, such a malfunction manifests itself in the form:
- The engine starts poorly or does not start at all.
- Interruptions in work, when you press the gas, the engine "chokes" and stalls.
- Too high idle, the saw "roars".
- Increased gasoline consumption.
- The saw does not develop speed well.
Do-it-yourself adjustment of the carburetor of the Stihl 180 chainsaw will not be difficult.
It has 3 adjustment screws. One is responsible for idling, and the other two for fuel. Usually a simple adjustment is enough to make the saw work again, as it should. If this did not happen, then the carburetor should be cleaned with its complete disassembly. Before completely cleaning the carburetor, you should also flush the fuel filters, breather and tank. Otherwise, the entire system will be clogged again. For some reason, most people only flush the carburetor, ignoring the rest of the fuel system. It is best to disassemble and set up this element using the standard manual “Chainsaw Stihl 180 instruction manual”.
This manual describes in detail the scheme of the carburetor device, which has a difficult detail.
Alternative fuel option
For refueling household and professional chainsaws, it is recommended to use AI-92 motor gasoline that does not contain alcohol components and additional additives.
The question of whether it is possible to pour 95 gasoline into a chainsaw is still controversial. Theoretically, the antiknock properties of AI-95 gasoline are higher than those of standard AI-92 fuel, but in practice it is better to give preference to the second option.
The problem lies in the fact that in order to improve anti-knock characteristics, manufacturers and distributors introduce additives into the composition of 95th gasoline, the quality and effectiveness of which causes reasonable doubts among specialists.
Such fuel does not fully meet the required characteristics, does not have the proper stability during long-term storage. After 3-4 months of exposure, its working properties deteriorate by 25-30%.
How to replace expensive oil
The disadvantage of special branded chain lubricants is their high price. Buying a liter of another expensive oil is not burdensome. And if there is work to be done that requires several liters, or even tens of liters, then thoughts about saving will certainly arise. The main thing is not to go to extremes when considering options. You can save on oil to such an extent that you have to change the chain several times, or even the tire itself or the oil pump.
There are three replacement options. Firstly, specialized products from little-known manufacturers can be used to lubricate the chain. But such oils still need to be looked for. In addition, there is a risk of stumbling upon a low-quality product.
The use of oils for automobile engines. They can be used as a temporary replacement, but they cannot boast of high adhesion, so the quality of their work will be clearly worse than special ones. For this reason, it is not recommended to use spindle and diesel oils - the worst in terms of adhesion.
And it is necessary to say about one more option - working off. This is the name of the oil that has worked out its life in the engine, and drained from it during replacement.
In fact, this is not an option at all. In mining, metal particles are necessarily present. And if they may not damage the chain itself, then they certainly will damage the oil pump and the entire lubrication system. On the forums on the Internet, you can find a “killer” argument in favor of mining - that the Soviet Druzhba chainsaw did not have chain lubrication at all and worked. So you can pour anything - and so it will do. Well, the “Calm” will also work with mining or even with a non-lubricated chain. The question is how long it will work and how many chains will have to be changed during this period.
A word of caution to those with a chainsaw under warranty. Masters of warranty workshops are able to identify cases of poor-quality chain lubrication. Especially when using mining. Refusal to repair under warranty will follow immediately.
Engine oil selection criteria
For self-preparation of a combustible mixture, in a dosed amount, heat-resistant branded engine oil recommended by the manufacturer is used.
- The specificity of this lubricant is the use in high-speed air-cooled internal combustion engines, which are equipped with household and professional chainsaws.
- Depending on the season, engine oil of different densities is used to prepare a combustible mixture, which retains its operating properties in the temperature range indicated on the label.
- Branded oils are recommended for use, providing full lubrication of the piston group and the connecting rod and crank mechanism in all operating modes of the power unit.
- Branded products differ in color. In particular, Shtilevsky mineral oils are red, synthetic ones are colored green. Husqvarna branded engine oils are blue or green.
Even taking into account the lower cost of mineral oils, it is recommended to use the advantages of synthetic analogues to prepare a high-quality fuel mixture.
Correct Proportions
In most cases, 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 performed as follows: one l \u003d one thousand ml, 1000/50 \u003d 20 ml or 1000/40 \u003d 20 5 ml, in other words, in the first case, pour 20 ml into each liter of gasoline, and in the 2nd - 20 5 ml of oil . If there is no annotation and you do not understand the proportions for making the consistency, then use the following tips:
- Tool and oil of the 1st brand. For example, for a Stihl chainsaw, the ratio of gasoline and Stihl oil will be the same as indicated on the oil container, usually 1:50.
- The substances used for the consistency have different brands - a proportion of 1:40 is selected.
- There is only one brand, but there is no information on the ratio of substances on the oil - they are diluted 1:40.
- In the absence of all data on the saw and oil, the mixture is diluted in a ratio of 1:40. The only thing you need to make sure that the oil is created for two-stroke engines.

For the running-in of the newest saw, 20% more oil is added during the first 3 refuelings of the fuel tank. In this case, instead of the ratio of 1:50 it will be 1:42, and the ratio of 1:40 will be converted to 1:33. For a liter of gasoline, you will need 20 four or 30 three ml of oil, respectively. No other running-in activities are carried out with the latest saw. Manufacturers recommend working only at the highest speed at all times. After running the tool, the usual proportions of 1:50 or 1:40 are used. In some cases, the manufacturer of the equipment also shows other ratios, for example, 1:25 or 1:32, they must be observed.
Risks of using fuel and oil surrogates
The design features of internal combustion engines of domestic and imported chainsaws exclude the use of more affordable biofuel and gas condensate gasoline substitutes. The performance of such fuel is currently far from perfect.
In the total volume of sales of motor oils, counterfeit lubricants, according to various sources, range from 8 to 15%. Only an experienced specialist can distinguish original products from fakes.
To eliminate possible risks of early failure of the saw, it is recommended to purchase consumables at branded outlets and representative offices of dealer companies.
With all the external similarity, it is forbidden to use oils for two-stroke internal combustion engines of mopeds and light motorcycles to prepare a working fuel mixture. The use of non-recommended lubricants may cause the service departments to refuse warranty obligations.
Octane number
This is where the fun begins. Is it possible to fill a ninety-five chainsaw with gasoline? In all annotations for the operation of chainsaws, manufacturers indicate in bold: "Do not use gasoline with an octane rating higher than 92 for the manufacture of fuel consistency." It is understandable, but apparently not to many, because From time to time, chainsaws with a burnt-out cylinder are brought to service centers!
READ Stihl 180 Chainsaw Starts And Stops
Let's figure out which gasoline is worth pouring into a chainsaw and which is not! For all two-stroke saw engines, ninety-two gasoline must be used; the tool is specifically designed for it. Filling ninety-five gasoline, detonation will begin to occur in the engine (piston push in the opposite direction), something like a micro impact that will occur with almost every revolution of the crankshaft. About ninety-eight gasoline, I think everything is clear, the effect will be even stronger, and these will already be mini blows.
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 options, this is a ratio of 50:1 and 40:1. Chainsaws operating on a gasoline-oil mixture in a ratio of 25: 1 are much less common.
- According to manufacturers of branded chainsaw equipment, their products do not need to be run-in. However, during the first hours of operation, experts advise operating a new chainsaw on a fuel mixture with a high oil content and, if possible, in a gentle mode.
For the 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, so 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 lubricating and cooling the saw set, therefore they are not suitable for preparing a fuel mixture.

The operation of the tool always begins with its preparation for work. What kind of gasoline can be poured into a Stihl chainsaw? What to pour gasoline into a chainsaw, what to fill. In the case of a chainsaw, this is first its refueling. What kind of gasoline to fill in a chainsaw Stihl? And although refueling a chainsaw in itself is not an extremely complicated operation, its incorrect or inaccurate performance can become a prerequisite for a severe threat of tool breakage and injury to the person working with it.
Fuel mixture preparation
In fact, all engines of chainsaws currently available are two-stroke. In practice, this means that for their normal and non-hazardous operation, they do not need clean gasoline, but a fuel mixture of gasoline with the addition of engine oil in a certain proportion. This is a feature of all two-stroke engines: their lubrication during operation is carried out by oil entering the cylinders simultaneously with the supply of gasoline.
The optimal ratio of engine oil and gasoline in a chainsaw mixture is considered to be 1:50.
Usually, the chainsaw manufacturer indicates the preferred octane number of gasoline for optimal engine operation and the recommended brand of oil in the instruction manual that comes with it. Pour not pure gasoline, but in a mixture with which gasoline to pour into the chainsaw.) c. What kind of gasoline can be poured into a Stihl chainsaw? What to fill in a 2-stroke engine with oil. 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. What kind of gasoline do you need so what kind of gasoline to fill in a chainsaw? Husqvarna, partner. But in the vast majority of cases, a ratio of 1:50 is used, and quite often this ratio is used when there is no instruction manual (for example, when buying a used chainsaw).
But such actions still cannot be considered fully justified. What kind of gasoline to pour into a Stihl chainsaw? What to fill the volume of oil, but in. 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 kind of gasoline to fill in 92 or 95 on a chainsaw? What kind of pouring gasoline into a chainsaw, they are not intended for a chainsaw, why do you need a manual one. The only thing that is justified is to allow, when preparing a fuel mixture for a used chainsaw, in which the engine is already very worn out, to increase the initially recommended amount of engine oil added to gasoline by 5-6%.

To prepare the fuel mixture, it is advisable to use a special container with marks on the body.
The ratio numbers indicate the number of parts of gasoline to 1 part of oil. If we translate the ratio of 1:50 into a more familiar system of measures, then this means that 20 ml of oil is needed for 1 liter of gasoline. What kind of gasoline to fill in a chainsaw Stihl? Clean gasoline, do not try to pour.) c. The fuel mixture is prepared in compliance with the specified proportions in a certain sequence.
Oil is first completely poured into an iron container, then half of the required volume of gasoline is added to it.

Chainsaw refueling sequence
So that no unpleasant incidents occur during start-up and subsequently during the operation of a refueled chainsaw, you must strictly follow the rules and sequence of its refueling:
When refueling the chainsaw, the necks are directed upwards and wiped dry, and fuel is poured into the funnel, all covers are carefully clogged.
- to perform refueling, you need a clean and even surface;
- do not refuel close to sources of fire;
- the necks of the fuel and oil tanks must be turned upwards during refueling;
- before refueling, the mouths of the tanks must be wiped with a clean, dry rag;
- the fuel tank cap must be removed with the utmost care to prevent spillage of fuel residues;
- fuel must be poured into the tank slowly and carefully, it is better to fill it with a funnel;
- oil in the oil tank must also be poured with extreme caution;
- the cap of the filled tank must be screwed up to the stop and fixed with a latch to prevent its spontaneous unscrewing;
- refueling tanks must be absolutely sealed; if the slightest leak is detected, it is strictly forbidden to start a refueled saw;
- you can’t start the chainsaw at the very place where it was refueled: you need to move at least 2 m;
- Do not smoke or use open flames while refueling.
Remember that following these simple but very important rules is the key to your safety during refueling and in the future while working with a chainsaw.
Features of refueling a chainsaw
For refueling imported chainsaws, gasoline below A-92 cannot be used, and A-76 is also suitable for domestic products. Immediately before pouring the mixture into the tank, it must be shaken again directly in the container until a uniform color is obtained.
You need to refuel the chainsaw carefully, without spilling the mixture past the fuel tank.
For the same reason, you should not fill the tank completely, you need to leave at least one finger of free space in it.
To control the level of the fuel mixture in the tank, it is released with transparent walls.
Chainsaw fuel system: 1 - fuel filter, 2 - carburetor, 3 - manual pre-priming pump.
The volume of the fuel tank of a chainsaw with a power of 2 kW (which corresponds to 2.7 hp) is slightly more than 0.5 liters. During continuous operation at maximum load, the average fuel consumption is 1.2 l / h. It is easy to calculate that one gas station is enough for about half an hour of intensive work. What kind of gasoline can be poured into a Stihl chainsaw? What kind of gasoline to pour in for a chainsaw. What kind of gasoline can be poured into a Stihl chainsaw? What kind of gasoline to pour into a Stihl chainsaw? Flood. For less powerful chainsaws, in which the tank volume is smaller, and the operating time on one gas station is reduced.

In addition to refueling the fuel tank, the design of the chainsaw has another tank, which also needs to be filled simultaneously with refueling. What kind of gasoline to pour into a chainsaw for preparing a fuel mixture? In petrol. To dilute gasoline in a chainsaw, take what brand of gasoline to pour? Calm in the chainsaw. This tank is designed for special chain oil. It is easy to distinguish between them - the fuel tank cap usually has a filling station logo, and the oil cap has a stylized image of an oil drop.
Manufacturers of chainsaws for chain lubrication produce branded oil containing special additives to help keep it on the chain. But it is quite expensive, so chainsaw owners often replace it with gear or engine oils in order to save money.
Such a replacement is not welcomed by chainsaw manufacturers, but it does not have a noticeable negative effect on the operation of the tool, except for a slightly higher replacement expense compared to the original oil.
The flow of these two tanks is adjusted so that the oil production in the oil tank slightly lags behind the production of the fuel mixture. What gasoline to fill in a chainsaw and others.

Recommended sequence
In accordance with the standard fuel mixture preparation technology, the calculated amount of oil is poured into a half-filled reservoir.
The mixture, with the stopper closed, is thoroughly mixed, after which the rest of the gasoline is poured. This sequence contributes to the uniformity of the resulting composition.
It is advisable to prepare fuel for a chainsaw in an amount sufficient to perform a one-time job. The finished composition at a standard temperature of 20 ° C can be stored for no more than one month. At higher temperatures, the shelf life is reduced to 2 weeks.
An expired mixture initiates the formation of resinous compounds that contribute to clogging of the jets, the formation of carbon deposits and limiting the mobility of the piston rings. In order to save money, the overexposed composition can be spent by adding up to 15-20% of the total volume to the fresh mixture.
