Gasoline to oil ratio for the STIHL grass trimmer
build gasoline for chainsaw
For 1 liter of gasoline, add 30 g of special engine oil. The resulting mixture is poured into a special compartment for fuel.
to build gasoline for your chainsaw. Before that, you need to consult with experts. Better to ask those who work in the service center to repair them.
And the sellers who advertise them in the supermarket, and will hang all the noodles on our ears, we will not be offered anything.
I was like that, but not with a saw, but with a scythe. I worked poorly, did not start a lot, exploded strongly and did everything mixing gasoline and oil, as the sellers said.
But when I went to the service center. said a completely different ratio of fuel parts.
For a saw, it is necessary to take AI-95 or AI-92 gasoline and mix in relation to oil. in 1 liter of gasoline 40 g of oil.
How to build gasoline for a chainsaw
To ensure that the chainsaw works for a long time and does not cause repair problems, it is necessary to properly prepare the fuel mixture. Internet forums are teeming with questions about this topic. We interviewed experts and put together a quick guide.
Use AI-92 or AI-95 gasoline to prepare the fuel mixture. Lower octane will not work. The gasoline is not necessarily running (otherwise the engine will fire) and not old (octane can change over time). Do not use boat and 4-stroke engine oil.
Main problem. these are proportions. Excess oil will cause deposits on pistons and spark plugs. Excessive gasoline will cause piston blockages and early engine breakdown. On average, one liter of gasoline is mixed with 20-50 ml of oil. For example, STIHL and Husqvarna recommend taking 4 liters of gasoline with 100 ml of oil. This ratio is optimal for chainsaws up to 1.5 kW. For chainsaws with a power of more than 1.5 kW of the same brands, use a ratio of 1/50 (100 ml of oil per 5 liters of gasoline). Recommendations from partner and Jonsered: 1/33 share (3.3 liters of gasoline. 100 ml of oil). The supersynthetic oil is added at a rate of 100/1. These figures are approximate. Always use the information provided in the instructions for your specific chainsaw model. Trust the numbers on the oil labels to a lesser extent.
How to dilute gasoline with a chainsaw?
As fuel for the chainsaw, gasoline is used with a high octane number: AI-92 or AI-95.

What to pour gasoline into a chainsaw?
The work of any chainsaw, a wide selection of which is available at zakazik.ua/products/benzopila.html. 2-stroke engine, the design of which does not imply the presence of an oil pump. This is why they only fill a mixture of gasoline and oil. It is strictly forbidden to use gasoline in its pure form.
Fuel mixture for STIHL fs 55 petrol trimmer
I decided to show how I prepare the mixture for the benzotrimmer. For correct and long-term operation of the tool, the correct
What to mix? On sale are canisters with sized sections and two holes. for oil and gasoline. Pour in the ingredients, twist off the lids and stir by tilting the container.
Many people use glass and plastic bottles, baby horns and syringes. Be careful with glass and plastic, and beware of static electricity. Do not allow solids or water droplets to enter the mixture. Remember to stir the mixture thoroughly.
Finished fuel cannot be stored for more than 25-30 days. The oxidation process changes its composition. Engine malfunction caused by overexposed fuel is not guaranteed. The amount of repairs reaches 80% of the cost of a new chainsaw. At the end of the working season, use the remaining fuel, stop the engine, remove the remaining fuel mixture.
Remember what your goal is. create a mixture that will ensure smooth operation of the engine, complete combustion of fuel without the formation of carbon deposits, smoke or a bully.
The proportions of the mixture for refueling the chainsaw
The specific proportions must be indicated by the manufacturer in the instructions for use. Quite often they write that it is necessary to fill AI-95 gasoline. But the octane number in domestic fuel is added to various additives, which significantly reduces its quality. Therefore, it is recommended to use AI-92 gasoline for refueling modern STIHL band saws.
The oils are selected specialized for a two-stroke engine corresponding to the class of a power chainsaw. the best option would be a mixture of the Shtil brand of the same name. They are red (mineral) and green (synthetic).
The fuel mixture of gasoline and oil is prepared in strict accordance with the manufacturer’s recommendations. For chain saws The rest of the proportions is usually 1:50, that is, 1 gram of AI-92 gasoline should be added with 20 g of oil.
Measure the amount of oil you can in any way. syringe or any measuring utensils. But the most convenient to use are the dispenser bottles in which the oils are produced by STIHL.
What gasoline to fill in the STIHL chainsaw
Poor quality fuel can damage your tool. STIHL chainsaws are usually refueled with unleaded gasoline, where the number of lead-free additives exceeds 90. AI fuel is completely suitable for this. 92. AI is also used. 95, which is used much less frequently. It is manufactured on the basis of AI. 92, but contains various additives that are deposited on the internal elements of the engine and can disrupt the operation of the mechanism. In this case, it is permissible to mix both fuels to achieve an optimal result.
It should be remembered that it is recommended to use fresh gasoline. during long-term storage in closed containers, useful octane properties are lost.
Calculation of the proportions of the fuel mixture
In the event that the substances for the mixture have different brands, it is recommended to use a ratio of 1:40.
When rolling a new chainsaw in the first 3 fillings, 20% more oil is added. In this case, 1:42 will be used instead of 1:50, and 1:40 is replaced by 1:33.
Violation of the ratios of fuel substances can lead to the formation of scoring, as well as to the appearance of carbon deposits on the spark plugs and pistons.
How to choose oil for chain or motor lubrication
A good lubricating mixture prolongs the life of your chainsaw and guarantees high quality work. It is recommended to use STIHL branded chain oil recommended in the instructions for new tools. Otherwise, the chainsaw may be removed from the warranty service. for non-observance of the operating conditions. At the end of the warranty period, you can use any other brand of oil. It should be remembered that it needs to be replaced twice a year.
STIHL has developed a complete range of lubricant mixtures for two-stroke engines. High cleaning power will improve the environmental friendliness of your tool.
All synthetic oils are made on the basis of primary raffinates, which can reduce the amount of emissions and prevent damage to the moving parts of the chainsaw during continuous operation.
STIHL HP oil is a mineral based oil with excellent combustion and lubrication properties. Available in various volumes from 20 ml to 55 liters.
HP Ultra Oil. Suitable for extended use of the tool. Provides complete combustion of the fuel mixture and thoroughly lubricates the necessary components. Highly biodegradable. over 80% in 21 days.
SAE 30 engine oil. used for all operating conditions in the garden. Helps reduce fuel consumption and features high quality base oils.
Motor oil 10 W-30. designed for 4-stroke engines. Temperature resistant up to. 30 ° C.
Depending on the design of the chainsaw, the refueling process may vary.
Using a special tool:
- Find a level and clean surface for refueling. Place the tool with the filler holes facing up.
- Wipe your chainsaw thoroughly with a clean cloth.
- Remove the fuel tank and saw chain oil reservoir using a combination wrench or wrench.
- Start refueling carefully. Take care not to splatter the mixture. Fill the tank with fuel and the tank with oil. The filling can be controlled by the transparent walls of the tanks.
- Tighten the tank caps securely to prevent accidental opening. Carefully monitor the tightness of the system. Do not start the engine if fuel leaks. it can pose a threat to your life.
In all other cases, observe the following refueling sequence for your STIHL chainsaw:
- Choose a flat and clean surface for the necessary manipulations.
- Clean the area of the filler openings from possible contamination.
- Pull the latch up and turn the tank cap counterclockwise as far as it will go to remove it.
- Fill fuel tank and oil reservoir carefully.
- Turn the covers until they stop and close the latches. If fuel is leaking, do not start the engine. it is dangerous.

Petrol. Energy Education
Petrol. also known as gasoline . it is a high-density secondary fuel that can be considered energy currency. It is used to power many heat engines, and most importantly, it fuels a large proportion of cars. Gasoline is produced when crude oil is broken down into various petroleum products in a fractional distillation process, and the finished product is then distributed to gas stations through pipelines.
Gasoline is required for most internal combustion engine vehicles to operate. Because of this, gasoline is one of the most widely used petroleum products. Gasoline accounts for about half of all petroleum products used. In contrast, diesel was
20%, and kerosene (or jet fuel)
eight%.  The price of gasoline is changing dramatically around the world and this affects the cost of running a vehicle. In addition, the global economy is increasingly intertwined with oil production and prices, which affects our lives far beyond the cost of filling a full tank of gas. [four]
How to breed
STIHL saw fuel mixture is prepared by mixing high-octane gasoline and two-stroke engine oil. The proportion of oil and gasoline for a chainsaw is as follows: if the power of the unit does not exceed 1.5 kW, then the ratio will be 1:40 (i.e. 25 ml of oil per liter of gasoline), and with a power higher than this value. 1:50 (20 ml for 1 l).
Looking at the table of proportions, we will analyze, using the example of two saws of different power, how to mix oil gasoline.
- For the low-powered STIHL MS 180 with a 2-stroke engine, the dilution will be 1:40. The volume of the fuel tank is only 0.25 liters. In order to mix fuel with oil for one filling, we need 6.25 ml of oil for 0.25 liters of gasoline.
- For the STIHL MS 660 heavy-duty professional chainsaw, dilute oil and gasoline in a ratio of 1:50. This model has a fuel tank capacity of 0.825 l. In order to understand how much oil to pour for such a volume of gasoline, multiply 0.825 by 20. It turns out that 16.5 ml of engine oil is required.
In practice, of course, it is not necessary to calculate what proportion of the lubricating fluid will be diluted in the volume of gasoline per filling. Usually, the fuel mixture is diluted in a volume of 1-2 liters, which is enough for several refueling of the chainsaw.
Dilute the gasoline for the STIHL chainsaw in a separate canister, in no case pouring the components into the saw’s gas tank separately. These engines do not have an oil pump and the possibility of installing it, so only ready-made fuel is poured into the tank. There are even special canisters with two necks on sale to make it easier to dilute the mixture, but you can add oil to gasoline for a chainsaw and in an ordinary canister.
It is better to observe the proportions of refueling the chainsaw as accurately as possible: excess oil will create carbon deposits on the spark plugs and pistons and provoke detonation during fuel combustion. This can shorten the engine life. In addition, the user of the saw in this case is forced to inhale the exhaust gases with unburned fractions. At the same time, excess gasoline can damage pistons due to insufficient lubrication.
Some folk craftsmen, in the absence of special measuring accessories, advise using a plastic bottle: a full cap (from the same bottle) of oil is poured into a half-liter container filled with gasoline. The output is an approximate ratio of 1:50.
It is better to calculate the amount of mixture for refueling in advance based on the expected amount 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 consume about 1.2 liters per hour of operation (for more precise characteristics of the saw, see the instructions). Thus, it makes no sense to prepare a mixture in volumes exceeding 3 fillings in a row.
Before starting the preparation of the mixture, it is recommended to thoroughly clean and dry the neck of the canister and the area around it in order to avoid the ingress of impurities: dust, water, etc. The same is done with the tank before filling the fuel: the lid and neck are cleaned of dust and adhering dirt, so that it does not get into the gas tank, and then into the engine.
Add remaining gasoline and shake for another 10-15 seconds.
Every chainsaw has three main elements that make it work. These include a 2-pin carburetor engine and two tanks. One is filled with the fuel mixture, the other is filled with the oil necessary to lubricate the chain. The volume of the fuel tank is 0.25 liters, which allows you to work without stopping for 45–55 minutes. The volume of oil is about two times less. With this ratio of volumes, the contents of both tanks end almost simultaneously.
When operating 2-stroke engines, the oil pump system is not used, therefore, for the STIHL chainsaw, oil must be added to gasoline to lubricate the shaft, piston and other rubbing parts. Attempts to run on one gasoline or non-observance of the proportions specified in the instructions for drawing up a fuel and lubricant mixture of two components lead to a breakdown of the tool.
What’s the difference between oil and gasoline?
With constant media coverage of rising or falling oil prices, fuel and gasoline prices, and the price of a barrel of crude oil, it can sometimes be difficult to tell the difference between oil and gasoline. To ease confusion, both are surrounded by many related terms that are sometimes misused. Understanding the individual properties of oil and gas and how they relate to each other will make it easier to understand the differences between them.
Gasoline is produced from crude oil in refineries around the world.
When oil is referred to in a gasoline company, crude oil. this is exactly what it is for. Crude or unrefined oil is also called oil. Oil. It is a naturally occurring liquid fossil fuel made up of a variety of hydrocarbons and other organic compounds found in rocks on the earth’s surface. Crude oil is useless until it is processed into various products. Oil is extracted from the ground using wells and sent to a refinery where hydrocarbons are separated during distillation and other chemical processes. After the oil is distilled, it is used to make a variety of petroleum products, with fuel derivatives being the most common.
Pool of crude, unrefined oil.
The main difference between petroleum and gasoline is that gasoline is a fuel derivative of oil. Its name is abbreviated to “gas” in the United States and is called “gasoline”, which is abbreviated from “petroleum alcohol” elsewhere around the world. Other fuel derivatives of petroleum are ethane, diesel, jet fuel, kerosene and natural gas. In addition to fuel, refined oil is also used to make olefins, lubricants, wax, sulfur or sulfuric acid, tar, asphalt and many other products.
Gasoline obtained from crude oil is used as fuel for internal combustion engines.
specifically, gasoline is a liquid petroleum derivative that is mainly used as a fuel in internal combustion engines. Produced in refineries; however, this type of primary gas does not meet the specifications for modern engines. Generally speaking, today’s gasoline is composed of a mixture of three different derivatives: paraffin, naphthenes and olefins. The mixing ratios depend on the refinery processing, the crude oil used and the octane number of the gasoline to be produced, which is a measure of the gasoline’s resistance to normal combustion.
Refined oil is used to make asphalt.
Drilling and extracting crude oil from underground, combined with the burning of oil and its derivatives, has created major social problems for the environment. One of the biggest challenges is oil’s contribution to global warming. Burning oil and its derivatives such as gasoline releases carbon dioxide, which is believed to contribute to global warming.
Gasoline can be stored in a bank for emergencies. Motor oil is used to lubricate a car engine. Oil well. Gasoline is purified from light oils extracted from underground wells. Gasoline is made from crude oil. Gasoline is a fuel oil derivative, while oil is the main ingredient used in products including gasoline. Crude oil is separated into products such as gasoline and kerosene in cracking columns in refineries. ,
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
Mixing 2-Stroke Fuel for STIHL Machines
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.

What to do if the saw stalls at idle speed?
If the STIHL MS 180 chainsaw stalls some time after starting in idle mode, then this indicates a breakdown of the fuel pump. To verify this, you need to use a vacuum gauge. If the device showed a pump malfunction, then the mechanism will need to be replaced.
Another reason for the malfunction is the wear of the STIHL MS 180 oil seals. After a long use of the saw, they lose their shape and elasticity, passing a large amount of fuel. If the oil seals are worn out, they will need to be replaced.
Recommended brands of fuels and lubricants for powering chainsaws
The specific brand of gasoline for the saw is always given in the manufacturer’s instructions. It is recommended to strictly follow it.
The octane number can often be slightly lower than the declared one. it is recommended to use a higher grade gasoline. For example, if the instructions say to use 92nd gasoline, then it is worth buying at a gas station and filling only the 95th in the tank.
- for engine,
- for chain and bar lubrication.
Do not confuse or misuse them. This is guaranteed to cause damage to the tool. Repairing it can cost almost as much as a new saw.
Do not try to use motor vehicle oil. The engine will be damaged very quickly. Automotive lubricants are designed for a different power plant and for different operating temperatures.
The most popular chainsaw lubricating oils are:
Each container with branded oil always indicates the proportion of oil and gasoline for the chainsaw (STIHL, Husqvarna, Partner, Ural), which must be adhered to when making the mixture.
