The proportion of oil and gasoline for the chainsaw “STIHL”: types of oil, selection of gasoline and proper mixing
Many users of the benzo tool relate to the preparation of the fuel mixture quite irresponsible. For example, I met the owners of the saw who diluted gasoline with oil “by eye”. They just poured as much as they want, and then came to me with a faulty tool.
It is important to understand that more, as less, does not mean better. It is the golden mean that is important.
If you prepare a mixture with a shortage of oil, then everything is clear. There will be a sufficient amount of lubrication for the cylinder and bearings, which means friction and temperature will increase, bunks are formed in the cylinder and can jam the crankshaft bearings.
And what will happen if you pour? A large volume of oil, during combustion, form a lot of residual combustion products that settled on the piston, in the exhaust window of the cylinder and muffler, making the movement of exhaust gases. As a result, a drop in power or complete loss of performance.
Freight that is formed with an excessive proportion of oil can settle under compression rings, preventing them from compensating the temperature expansion, which will entail bulletin, in general the consequences can be quite serious.
The device of the lubrication system
Depending on the brand of the chainsaw, the details of the lubricant can differ a little structurally, but their total number and connection scheme remains unchanged. The main components of the details of the lubrication system are:
Oil tank located, as a rule, in the engine crankcase.
Preparation of fuel mixture for a chainsaw
Gasoline should be with an octane number no less than AI92. You can also fill in AI95, but its quality at our gas station leaves much to be desired, so if you are not sure of the 95th, it is better to take gasoline AI92 gasoline to dilute gasoline into a chainsaw. You should not take gasoline in the same way for a long time in the canister, tank or any other capacity. Gasoline for the preparation of the fuel mixture in the chainsaw should be fresh, otherwise it loses its properties, in particular the octane number, and even if you run the chainsaw on such fuel, it will not give out full power. And the saddest thing in this case is that the failure of the chainsaw due to poor.quality fuel is considered a non.warranty occasion and leads to expensive repairs. Sometimes it’s easier to buy a new chainsaw than to repair it after such a breakdown!

Oil for 2-stroke engines according to the American Petroleum Institute (API) classification, the American Oil Institute has an API-TB class, there are also API-TC oil oils, but they are designed to work with less loads than most of the chainsups we common. If we take the classification class of Japan Automobile Standards Organization (JASO) Japanese standardization organization in the field of automotive industry, then focus on JASO-FB and JASO FD classes (see.Table 1 below.).Not in any case do not use oil for four.stroke engines! Remember that in a two.stroke engine the oil should be completely burned, which means it is better to take synthetic oil, since it gives less smoke and burning residues. And if you pour oil for four.stroke engines in your chainsaw, which will not burn completely and as a result of the fog, then you will fail. The best thing to be guided by when choosing oil for a chainsaw is an instruction for her.
When preparing a fuel mixture of gasoline and oil for a chainsaw, be sure to see the manufacturer’s recommendations. Why is it so important to observe these recommended proportions? With a small amount of oil in gasoline, the cylinder and the piston will occur and the bulletin will occur, and this is the exit of the CPG and repair. If there is a lot of oils in gasoline, then this is a dozen and the failure again.Each manufacturer has its own recommendations on proportions (see.Table 2 below). Try not to store the finished mixture longer than a month. Do not store it under direct sunlight and openly. Avoid water and dust, this will lead to the failure of the carburetor, since the fuel filter is often not able to completely clean the fuel.
Since they often come from search engines at the request of the same “how much oil is pouring 1.2.5 liters of gasoline”, then I add another table under which you can find out how much oil to gasoline according to the accepted proportions. The proportions can be viewed in table 2 or, more precisely in the instructions for your chainsaw.
The choice of oil
Unlike four.stroke engines, STIHL 180 chainsaw oil is poured directly into the gas tank, having previously mixed with gasoline. It is recommended to pour the oil specified in the instructions for this model in the chainsaw.
In no case can you use oil intended for low.speed engines (boats, scooters, etc. D.).
It can significantly reduce the life of the motor, and if traces of such a substance in the cylinder-piston group are detected, the tool will be considered removed from the guarantee, t. e. will not be subject to warranty repair or exchange.
Synthetic and mineral oil oils for chainsaws STIHL are sold in bottles or cans of different containers: from 100 ml to 5 liters. Minerals have a lower cost, and semi.synthetic and synthetic provide complete combustion in the process of engine operation, t. e. lack of soot and a minimum of toxic compounds in the exhaust.
In addition, synthetic oils retain their qualities in a much wider temperature range, as well as contain special additives that are useful for engine operation: anti.orally, detergents, cannibal, etc. D.
You can choose motor oil for your tasks depending on the model of the saw and the frequency of its use: the oil consumption during the operation of the device is low, and given the shelf life of semi.synthetic and mineral lubricants, there is a risk of simply not having time to use even a liter bottle to the end.
So with small alleged volumes of work, you can not buy a voluminous canister, but limit yourself to a bottle. The expiration date does not have only mineral lubricants of Stihl.
Let’s talk about the installation of oil supply directly to the chain
First of all, I would like to put Accent on the fact that all the STIHL manufacturer’s chainsaws have quite small sizes, but, nevertheless, they are very powerful. It is these features that attract potential buyers of this kind of technology to the models of this company. over, you can easily produce various kinds of manipulations with this device regarding work with wood (see. how to cut down a tree).
Device for supplying oil to the circuit
In addition, Stihl chainsaws have a high level of cutting ability. over, this technique is equipped with the latest accessories (see.Nazadka for the chainsaw angular grinding) is additional due to which they contribute to convenience and ease of work. But actually let’s talk directly about the device itself, which the manufacturer has equipped with his chainsaws. So, the system of direct chain lubrication of the Stihl chainsaw consists of:
It is worth noting that the direct oil feed through the operation of the pump has a special adjustment. An important fact is that the chain is lubricated throughout the work of the chainsaw. It is for this reason that this part serves its owner for a rather long time.
During the operation of the device from the groove groove, the oil begins to exit directly and is immediately absorbed by sawdust.
That is why the process of lubrication of the chain area is carried out automatically. But it is worth noting that there are models that have the so.called “dosage” of oil, which should be supplied directly to the chain. And naturally models, the price category of which is quite low, are located only by a manual pump directly through the impact of the drive, which is located on the handle.
Choosing oil mushrooms
For trimmers engines, it is necessary to choose oils with “2T” labeling, which are used for ICE with a volume of 50 to 200 cm 3 and have air cooling
First of all, when buying oil, it is worth paying attention not to the price, but the protective properties of the material, since slight savings can subsequently become a real headache for the owner and, as a rule, large costs
The main factor that determines the quality of the oil for a trimmer for grass is an alkaline number. It is this component that excludes the oxidation of the rubbing parts and slows down their destruction. During operation, the oil gradually loses its alkalinity and becomes oxidized. The optimal level of acidity (pH) should not be less than 8-9 units.
The viscosity of the oil for motorcycles also has a great influence on the process of gasoline tools. This indicator determines the possibility of operating a trimmer for grass at different temperatures. For example, summer grades of lubricants thicken even with a slight drop in temperature. Due to the use of the lawn mower exclusively in the spring-autumn period, oil with summer marking will be an excellent option.
The temperature of the outbreak for a trimmer oil for grass should be more than 225C, otherwise the oil will quickly burn out, and the piston group will be subjected to intensive wear.
Why is gasoline mixed with oil for gas station refueling
Dilute gasoline with butter needs to avoid failure of the internal combustion engine. The reason for this is the design features of the lubrication system of two.stroke engines. There is no camera in the design of such engines for filling the engine oil, and if you fill in the fuel without lubricating the material, then the crankshaft, piston, bearings and connecting rods will not receive grease. This will significantly reduce the service life of all these parts, so it is prohibited to fill in pure fuel.
Gasoline and oil for chainsaws are required to be poured in the appropriate proportions, which makes it possible to effectively lubricate the rubbing parts. The lack of lubrication or its excess will lead to negative consequences in the form of a carbon formation. In order for the tool to work properly, from the first day of operation of the tool, it is necessary to season it not only with high.quality materials, but also to observe the correct proportions.
It’s important to know! A two.stroke engine is required to pour gasoline with an octane number of at least 92. Many experts argue that it is possible to fill up or the Ukrainian type of fuel with an octane number, not lower than 95, which is associated with its low quality. In order for the engine to work properly, the main thing is to fill in it pure fuel without pollution
In order for the engine to work properly, the main thing is to fill in it pure fuel without pollution.
We deal with the choice of gasoline for the AI-92 or AI-95 lawn mower
How many people, so many opinions, which applies not only to the choice of oil for a trimmer for grass, but also gasoline. Similarly, in order not to make a mistake with the choice, it is recommended to use gasoline of the brand that the manufacturer recommends (indicated in the manual to the tool). However, not everything is so simple here, since at each gas station of the gasoline brand they are only called the same, but have a completely different composition. It is required to figure it out, and come to a single conclusion about which brand it is better to pour gasoline into a two.stroke engine for your trimmer for grass.
Manufacturers recommend using A-92 gasoline for their technique, and some models require the use of the A-95 brand that do not contain ethyl alcohol. It is not recommended to use gasoline of the AI-90 brand and below, as they will entail the rapid wear of engine parts. Buying gasoline of one brand, one cannot be 100% sure that it is true. The result is the following picture:
- The manufacturer recommends pouring fuel into a trimmer for the grass of the AI-92 brand
- The summer resident uses only gasoline of this brand, but buys it at gas stations, where the price is lower or where you have to
- This negatively affects the internal details of the motor, since at one gas station it is really high-quality AI-92 gasoline, and at the second, at best, if it is AI-80, not AI-76
As a result, the engine suffers, and after a couple of years of operation a new trimmer for the grass, it is necessary. In order not to analyze the quality of fuel or buy only expensive gasoline, it is recommended to refuel only at one gas station. At gas stations, gasoline is poured only into metal canists, not plastic.
There are manufacturers that produce special cleaned fuel for two.stroke engines. If this option is selected, then you will not need to choose the best gas station, a brand of gasoline and control its storage periods.
Oil for two.stroke chainsaw engines
Modern garden chain saws can be pre-equipped with 2- and 4-stroke power units. The engines of these two types are slightly different in terms of action and the scheme for using the added lubricant material. In powerful gross chainsaws with a 4-stroke ICE, the engine crooked-shawl is lubricated with oil, which is in the crankcase of the factory motor during the active operation of the gas tools. In 2-stroke factory ICE, the lubricant comes from gasoline directly to the cavity located under the standard piston-it is there that there is a crooked-shaped group equipped with a pair of bushings and bearings requiring continuous lubricant. That is why in the gasoline used for refueling for 2-stroke factory ICE you need to add motor oil.
In order to accurately choose a specific lubricant for the continuously rubbing parts of the power supply of the chainsaw, its owner must study the most important properties of the material:
- The volumes of the resulting ash. during the combustion of gasoline, the exhaust gas vapors appear, and when combustion of oil. ash and tarry deposits. They accumulate on the walls of the cylinder and the piston, which makes it difficult to make its unhindered movement up and down. Some manufacturers do not guarantee sufficient grease combustion, however, branded products are almost completely burned;
- The level of purification from extraneous impurities. in the composition of oils, may contain not only useful additives, but also harmful substances. A lubricant is considered high.quality, in which the percentage of harmful components will be minimal;
- anti.dimensional, anti.corrosion and continuously lubricating properties. the oil should cover the rubbing parts of the power unit with a thin film, thereby protecting them from increased wear, heating and exposure to rust.
When developing lubricants to maintain the operation of 2-stroke engines, manufacturers are guided by 2 standard: 2T and TC-W3. The second type of oil is used for operation in standard engines equipped with liquid cooling. such an internal combustion engine is equipped with hydraulic cycers and boat engines. 2T standard oils are used mainly for lubricating engines with constant air cooling. chainsaws, trimmers and other types of household appliances.
In the market, oils of such brands are the most popular among experienced gardeners and rollers:
Husqvarna. This Swedish manufacturer never saves on quality. Direct evidence of this is not only a proprietary garden technique, but also high.quality products for lubricating its parts. The oil of this brand. Husqvarna HP. contains a large number of additives aimed at stabilizing the work of the internal combustion engine. This oil is produced on a carefully prepared semi.synthetic basis and has substances that reliably protect the power unit from corrosion and increased wear. During continuous operation, the lubrication of the Swedish manufacturer burns almost completely, forming minimal volumes of ash;
- STIHL is the most famous brand manufacturer of garden technology. The lubricants of this brand have a balanced company composition, which contains all the required additives. STIHL HP oils can work properly during the operation of the saw at temperatures to.10⁰C;
- Partner-oils of this manufacturer of chainsaws are compatible with all 2-stroke power units. They are distinguished by increased lubricants, high m of anti.corrosion and anti.intelligent additives, as well as the ability to work stably at temperatures before.15⁰C.
When choosing oil for 2-stroke chainsaw engines, it is important to pay attention to its expiration date. The gardener should alert the manufacturer’s marks that the terms of the operation of its lubricant can be 3-5 years or more. After all, the additives contained in the oil have a tendency to evapon and loss of basic working properties
As a rule, well.known brands are advised to use their lubricants for 6-12 months, since after this time the oil becomes unusable
After all, the additives contained in the oil have a tendency to evapon and loss of basic working properties. As a rule, well.known brands are advised to use their lubricants for 6-12 months, since after this time the oil becomes unusable.
How to breed
STIHL fuel mixture is prepared by mixing high.octane gasoline and oil for two.stroke engines. The proportion of oil and gasoline for the chainsaw is as follows: if the power of the unit does not exceed 1.5 kW, then the ratio will be 1:40 (t. e. 25 ml of oil per liter of gasoline), and with a power above this value. 1:50 (20 ml per 1 l).
It is necessary to dilute gasoline for the Stihl chainsaw in a separate canister, in no case, without filling the saw in the gas tank of the saw separately. There are no oil pump and the possibility of installing it in these engines, so only the finished fuel is poured into the tank. There are even special canists with two necks on sale to make it more convenient to dilute the mixture, but you can add oil to gasoline for a chainsaw and in an ordinary canister.
The proportions of the gas station refueling are best observed as accurately as possible: the excess oil will create soot on candles and pistons and provoke detonation when fuel combustion. This can reduce the engine operating resource. In addition, the user of the saw in this case is forced to inhale exhaust gases with unburned fractions. At the same time, an excess of gasoline can damage the pistons due to insufficient lubrication.
To dilute gasoline, it is recommended to use special tools. this is a measured container for gasoline, a lubricant dispenser, a syringe, a canister for the preparation of the mixture and a watering can for refueling the sawdaulu a tank. All these auxiliary accessories are sold in official stores and at Stihl dealers.
Some people’s craftsmen are advised to use a plastic bottle in case of lack of special measuring accessories: a full cover (from the same bottle) is poured into a half-liter container filled with gasoline. The output is an approximate ratio of 1:50.
The amount of the mixture for refueling is best calculated in advance based on the estimated volume of work and the declared consumption of this engine. The volume of the tank in most chainsaws is about 0.5 liters, a 2 kW engine will spend about 1.2 liters per hour of operation (more accurate descriptions of the saw can be seen in the instructions). Thus, it makes no sense to prepare a mixture in volumes exceeding 3 in a row.
What will happen if the manufacturer’s recommendations do not take into account?
In case of violation of the rules for the preparation of fuel and lubricants and non-compliance with proportions when adding oil to gasoline at the Stihl 180 chainsaw; the following problems arise:
- With an increase in friction, the wear of the working surfaces of parts will increase.
- Due to the insufficient amount of the lubricant, the bearings will begin to collapse.
- The full functioning of the mechanical nodes is violated in connection with the premature wear of the parts, their service life is significantly reduced.
- When using low.grade varieties of gasoline and oils, the performance of the unit decreases with subsequent breakdown of important nodes and parts.
Fuel is prepared before refueling the saw, avoiding excessive contacts with oxygen. After the end of work, the remaining mixture must be drained.
Answers to frequently asked questions
We will briefly answer the most frequently asked the owners of the chainsaws.
Is it possible to pour car oil in a chainsaw?
Yes, you can. Once to perform simple tasks without serious loads. For example, we will present this situation.
Initially, no work was planned using a chainsaw. Therefore, specialized lubrication of 2t was not purchased in advance.
But upon arrival at the cottage, it was found that, for example, a tree fell on a fence. And it needs to be urgently divided and removed. In this case, you can use one.time lubricant.
How much oil is needed for a chainsaw in this case?
It is recommended to pour 30-50% more lubrication. The saw will smoke stronger, but the probability of piston damage will decrease. For example, it is better to take 2.5-3 grams of oil per 100 grams of gasoline. The main idea here is this: for a saw it is better inappropriate lubrication than without it at all.
Choose synthetics, semi.synthetics or mineral oil?
Here again it all depends on the type of saw and its constructive purpose, as well as the nature of the work. If the saw works in industry on the cut of thick logs or the processing of solid wood, and not at home (for household needs), in the long run, the use of synthetics or semi.synthetics may well be more profitable.

If the chainsaw is in domestic use, then an ordinary mineral water is quite suitable.
How to stir gasoline with butter?
The exact technology of the mixing procedure itself (not a proportion), which should be adhered to, does not exist. Usually an empty container with a measured scale is taken, gasoline is poured into it.
For example, 1 liter. After adding a lubricant is added. A syringe or a measured glass with a price of division of 1 ml is used for a fence of the necessary portion of lubrication. The mixture is thoroughly mixed and poured into the saw.
It is not recommended such a method as breeding oil with gasoline immediately in the fuel tank of braids for grass. Especially if the tank was completely dry before. Immediately after pouring into the tank, gasoline will fall into the fuel line without oil.
That is, after the oil is added, all the same, some time after starting the saw will work without lubrication. And this one is just at the time of starting and warming up, when the engine is required most.
What oil is the best oil for gasoline?
There is no unequivocal answer to this question. It all depends on the design features of the chainsaw and its operation mode. In any case, a win.win option would be the purchase of corporate oil from a saw manufacturer.
In general, the trend is this: the more lubricating the liquid is more expensive, the more reliably it protects the engine from wear and forms less deposits in the cylinder.
Today on sale you can find fake gas oil oils, which, at best, are a tinted vice.
Therefore, to buy two.stroke lubricants, especially branded, which are so fond of fake counterfeit manufacturers, is better in large authoritative networks.
The probability of buying a fake in large specialized stores is minimal. Such points of sale value their reputation and almost never contact fake products.
There are two more well.known manufacturers of chainsaws, the products of which occupy a considerable market share in this Makita and Patriot. Motor oil for chainsaws of these manufacturers is also produced under their own brands.
What oil for the makita chainsaw oil? Ideally, of course, the original from the same manufacturer. Lubricants manufactured under the Makita brand have a balanced set of qualities and a relatively low price among such branded products.
What oil for the Patriot chainsaw oil? There are also branded lubricants here. It is best to use them. And these oils are produced in several versions.
The line of company products also contain lubricants for chains. Lubrices for the chainsaws of the Patriot brand have proven themselves well. And today they are often used as alternatives and in another technique.
From domestic products, 2-stroke oil “LUKOIL” is pronounced brightly. At a low cost, this product has really impressive properties.
After its use in most cases, soot is not formed in the combustion chamber. LUKOIL oil mixes perfectly and has good lubricating and protective properties.
It is also worth noting such an immortal option as ordinary M8 motor oil. Despite the great abundance of specialized lubricants, many owners of the chainsaws use it in the old fashioned way.
This option is permissible in the short term and only for easy operating modes. But you need to be prepared for the appearance of heavy deposits, if you use motor lubricants on an ongoing basis.
In the industrial sphere, they cannot be used: it will greatly affect the saw resource. It is more reliable to use specialized lubricants.

The assortment of the company presents two types: summer SAE 30 and all-season 10 W-30, differing in viscosity and threshold of soot. The summer is recommended for operation at air temperature from 4 to 40 ° C, and all.season can be used in the range from minus eighteen to plus forty degrees Celsius. The basic recommendation for these products is the first replacement in the new engine after 5 motorized hours, the next. every 30 30 hours worked.
The ratio of gasoline and oil for chainsaw
Domestic and professional chainsaws are driven by two.stroke ICE, working on a dosed mixture of gasoline and adapted to difficult conditions of engine oil. Correct proportions of oil and gasoline for the chainsaw are one of the important conditions of stable traction characteristics of the engine and the low.cost production of its prescribed resource.
The need to obtain a sufficiently high power from a small.to.cubic power unit forces to operate chainsaw engines in high.speed modes, therefore, increased requirements are imposed on the quality of both components of the fuel mixture.
00 ml jars
A separate story, these are 100 ml jars.
Sellers in benzotechnics stores always confidently claim that to prepare the mixture, it is enough to dilute such oil with five liters of gasoline and that’s all, you can go into battle. But in fact, this is not so and we have just been convinced of this, so be careful and prepare the mixture correctly.
