Gasoline Dilution Chainsaw Oil
The most correct decision is to follow the recommendations indicated in the instructions for the product! In the absence of such an opportunity, you can use the special fuel preparation formula.
- Qualitative fuels and lubricants;
- Correct proportions;
- Tools and mixing technology.
If you want the tool to do its job perfectly and last for more than one year, you must provide it with the proper quality fuel and lubricants.
According to experts, it is necessary to use unleaded fuel with an octane rating exceeding 90. The gasoline A92 and AI92 are considered ideal. You can use the 95th, but there is an opinion that it is better to refrain from this kind of gasoline, since some of them are made on the basis of the 92nd with the addition of additives. The latter, in turn, although harmless to 4-stroke automotive engines, but they will be superfluous for the “sensitive” mechanisms of 2-stroke engines.
Gasoline for a chainsaw is recommended to use fresh, because when stored in cans, fuel can lose octane properties.
According to the international classification, oils of the following markings are used for chainsaws:
- Use oil only for 2-stroke engines;
- Do not use the material after the expiration date;
- It is strictly forbidden to add mining (it contains many unnecessary impurities. Harmful to the central mechanism of the chainsaw);
- Do not use chain lubricant (for each device: chain and engine. It is its own);
- The use of synthetics or semi-synthetics is preferable (during mining, it almost does not form combustion products, but the price of such a material is higher than that of mineral oils).
There are several options for the ratio of fuel and lubricant. As a rule, this number ranges from 20 to 50 ml of oil per 1 liter of gasoline.
We repeat, it is necessary to follow the instructions for the product or the recommendations indicated on the oil label (priority of the instruction). For lack of such, before you dilute gasoline, you need to pay attention to the power indicator of the product, since the created proportion directly depends on it.
For chainsaws with power:
- Up to 1.5 kW, the recommended ratio of 25 ml of oil per 1 liter of gasoline;
- Above 1.5 kW 20ml / L.
In gasoline for a chainsaw, the addition of oil is allowed slightly more than the recommended proportions (up to 5 ml per 1 liter). In this case, you should be extremely careful, because non-observance of proportions can lead to breakage, and as a result, costly repairs.
If you dilute gasoline with a large volume of oil, then during the operation the number of impact loads on the cylinder-piston system will be increased, and soot may form, as a result of which the CGP will fail.
Adding a small amount of oil to gasoline for a chainsaw can lead to insufficient lubrication of the surfaces of moving elements, which will lead to additional friction of the elements and their heating, followed by failure of the entire mechanism.
Not only the quality and proportion of fuels and lubricants is important (although it is dominant in this matter), but where and how (how) gasoline is diluted with oil for chainsaws.
The technology involves the use of tanks with graduated divisions, some brands (along with chainsaws and oil) produce containers for mixing and storing fuel. Made of special non-combustible material, they are available in canister or bottle forms, often endowed with measured fishing lines, and some of them have two entrances (separate for each type of fuel and lubricants).
Often, improvised means are used for mixing:
- Plastic / glass bottles;
- Syringe (without needle);
- Measuring glasses;
When using household products, be extremely careful, because during mixing during the interaction of combustible material with the surface of non-specialized containers, static electricity may arise. This is fraught with explosion. In the manufacture of the mixture, oil is added to gasoline, since it has a higher density.
It is recommended that a small amount of fuel be diluted without surplus. You cannot store such a mixture for a long time (the properties of gasoline are lost), up to a maximum of 25-30 days. Upon completion of the work, it will not be superfluous to drain the remaining fuel and idle to work out its resource. This is because storing the mixture in the product tank increases the wear of the seals.
Remember, the use of high-quality fuel and compliance with the manufacturer’s recommendations guarantee a long and fruitful operation of the product.
A chainsaw is used when cutting trees, in repair work. The popularity of this tool is growing every year. Each owner buys it at home. However, to use it for a long time, you must properly care for the tool. Only with quality care, the saw will last a lifetime and will not harm your health.
This is especially true in gasoline-oil mixtures. It must be diluted and filled strictly according to the instructions that will be given below.
Why dilute lubricant
At the very beginning, it is necessary to deal with the cause of the dilution of the fuel. The mixture used for the chainsaw is diluted primarily to extend the service to its owner. The instructions to it strictly prohibit operation without diluting gasoline.
The basis of the chainsaw motor is a piston internal combustion engine. It consists only of a cylinder, so it does not have additional systems for lubricating parts. The mixture enters it, settles, lubricates the piston rings and walls. In tools like chainsaws, oil with gasoline is a unique lubricant. The mixture extends the life of all parts.
In addition, it contains additives that are useful for engine operation. It has antioxidant, preservative and other properties that are also useful for the engine and its parts.
What proportions exist to dilute the components for the mixture
The quality of the chainsaw will depend on the correct refueling of the chainsaw with a mixture of lubricants and fuel. To determine the proportion of components and how to dilute the fuel, it is recommended to read the instructions. If you forgot how to dilute, or lost the instructions. You can contact the Internet for help. It should be said that the proportion between oil and gasoline for a chainsaw should be observed exactly.
The most common ratio of gasoline to oil is a 1:50 ratio.
That is, one liter of gasoline is diluted with twenty milligrams of lubricant. This ratio is quite suitable for tools whose power is more than one and a half kilowatts per hour.
For those chainsaws whose power is less than one and a half kilowatts per hour, it is recommended to mix gasoline with oil in a ratio of 1:25. That is, one liter of gasoline is diluted with twenty-five milligrams of motor oil.
It must be remembered that the presence of a large amount of oil in gasoline will lead to rapid wear of parts. When the level is exceeded, the loads on the cylinder and piston increase. Faster carbon deposits form faster.
In addition to the instructions, you need to know what oil you need to add for a chainsaw. Since there are many varieties, it is difficult for the ordinary owner of a chainsaw to choose the best of the proposed ones. Let’s consider some of them.
Proportions of gasoline and oil
For example, Stihl, along with quality saws, produces special lubricants that are used in these tools. Special oils are produced by companies such as:
The above three companies are simultaneously manufacturers of chainsaws and special lubricants for them. The next step in the proper maintenance of the tool will be the saw refueling algorithm.
How to refuel a saw
A plastic bottle is best for refueling a chainsaw. The volume of the container should be equal to two liters, if you will often use the tool. A smaller container should be used when you rarely use a saw.
Dilute fuel and lubricant in a separate bottle. The exact proportions indicated in the instructions must be observed. It is recommended that you leave an empty space so that the liquid mixes well.
Gasoline Dilution Chainsaw Oil
Such a mixture should be stored no more than two weeks. Shake the bottle before use. Experts do not recommend diluting a large amount of the mixture immediately and store it for years. Storage temperature should not exceed more than twenty-five degrees Celsius. If more, then the shelf life is reduced.
Chainsaw oil refueling
Long-term storage of the mixture greatly affects the traction capabilities of the engine. A carbon deposit forms, the ability of the pistons to move quickly decreases.
How to dilute the components of the mixture
As mentioned above, gasoline with oil should be diluted in a specially prepared container. Do not do this in a gas tank. The latest technology will cause some of the oil to fall into the carburetor. As a result, you will have to disassemble the engine and wash it.
The standard dilution ratios are 50: 1 and 40: 1. Such a mixture will not interfere with the combustion of gasoline in the gas tank and will improve the lubrication of the moving parts of the mechanism. When running a new tool, it is advisable to add twenty percent more lubricant. Diluting with large quantities of oil is recommended in areas with high air temperatures.
Many owners will be interested in information on how to dilute gasoline with oil, if there is no measured capacity. For this, twenty cubic medical syringes are suitable. Although most often measuring tanks are included in the kit for chainsaws.
Before diluting the fuel, it is necessary to clean and degrease the neck of the gas tank. It is desirable to fill in through the filter. Any rag will serve as a filter.
After use, the remaining mixture must be drained and disposed of. Remember that it’s better to overfill than underfill. What will happen if you do not take into account the recommendations, read below.
If you do not follow the instructions, you can bring the tool to an inoperative state. For example, if you do not dilute the fuel, soot will form more often, the necessary lubrication of the pistons will not occur, as a result of which the temperature in the engine rises. And this will cause the pistons to break. Or the owner of the saw will inhale large quantities of toxic fumes throughout the work. Thus, he will earn health problems, break the tool.
Mixing Oil and Gasoline
If you use poor quality lubricant and fuel, they can also lead to engine damage. It is not recommended to dilute engine oil made for cars. Fuel must be bought with a high octane rating.
Overview of manufacturers of oils for internal combustion engines
Synthetic materials retain their lubricating properties for a long time. With increasing temperature, they are able to not fade after the first heating. Do not emit toxic substances that can damage the health of the owner.
Husqvarna lubricant is used to lubricate chainsaw engines of the same company. It must be diluted in gasoline in a proportion of 1:50. Or 20 grams per liter of fuel. Lubrication of engines from manufacturers of another company must be diluted in a proportion of 1 to 33. That is, 30 grams per liter of gasoline. This component for fuel dilution consists of seventy percent mineral elements. Synthetic impurities are also added. But their share is a small part. 30 percent. This grease is intended for the CIS countries, where there are problems with high-quality gasoline.
Kreissman, an example of which was given above, is used for two-stroke chainsaw engines. It is necessary to dilute the oil with fuel in the same proportions as indicated above. “Kreissman” prevents the formation of soot, perfectly lubricates pistons and other engine parts.
Tool manufacturers usually complete their chainsaw with their own lubrication material. This achieves the best ratio of lubricating properties and increases the service life of the saw.

Leskhozes, forestry enterprises, private households buy chainsaws for specific production, household chores. Consider the correct proportions of oil and gasoline for a chainsaw. Today, the country’s liquid market offers an assortment of domestic and import mechanisms.
Power plants in chainsaws are internal combustion engines, fueled by certain grades of gasoline, diluted with the required parts of the oil.
Knowledge and strict observance of the compilation of a combustible mixture is the key to long operation, productive use of small-scale mechanization units.
The main fuel component is the AI brand. Below or above 92 octane is not recommended. Ideal for many types of mechanized sawmills of domestic or foreign manufacture.
The ideal ratio of gasoline and oil for a chainsaw:
- Increases unit productivity;
- Increases operational resource;
- Creates money savings.
The proportion of the mixture for “Stihl”
The German family-owned company Stihl has production facilities in many countries around the world. The office is located in Waiblingen. Among the manufactured assortment for the needs of forestry, a place of honor is occupied by small-scale mechanization means.
Today the Stihl chainsaw is in a liquidated golden age:
The manufacturer set the standard for dilution of oil in a ratio of 1:50. The proposed proportion establishes the ability to dilute 1 fraction of oil in 50 parts of gasoline. Or in a ratio of 1:40.
The calculation is simple. We know that 1 liter of flammable liquid equals 1000 milliliters. The value is divided by 50, we get 20 milliliters of oil. A similar algorithm determines its volume, recommended in a ratio of 1:40. After making simple calculations, we get the value of 25 milliliters.
Proportions for Swedish Husqvarna chainsaws
Depending on what power is required from the units, choose the appropriate component dilution:
From 40 to 50 parts of oil is diluted in one liter of fuel. These are ideal proportions of gasoline and oil.
Along the way, we inform you that only unleaded gasoline of the AI-92 or AI-95 grades is used. Leaded combustible product is considered an unfortunate choice for internal combustion engines, as it shortens the engine’s service life.
Husqvarna HP Structural Firm
The brand structure of the Swedish manufacturer Husqvarna HP includes a company that manufactures mechanized hand tools and lubricants for them, effective chemical additives.
The manufacturer for the Partner chainsaw has developed an original ratio of the proportion of fuel and oil for two-stroke power plants:
The mixing ratio of the fuel consistency is deduced by the standard formula 1:50. This is a constant. That is 20 milliliters per 1 liter of AI-92.
There are moments of non-compliance with the standard approach to dilution with a lubricant product of the company’s own production. This is when the ICE goes through the break-in stage. A fuel mixture of 1:40 is allowed for the engine.
Proportion for chainsaw Friendship
For engines, low octane numbers are used. The unit shows the highest performance when pouring AI-76 and AI-80 gasoline into the internal combustion engine.
It is recommended to dilute gasoline and oil according to the following algorithm:
Take 2 clean containers, dried from moisture with volume marks. Then dilute the fuel with push-pull oil in a ratio of 1:50. That is, the fuel is diluted with 20 milligrams of oil.
Need quality components
Practice proves the influence of the quality of the prepared mixture, taking into account the necessary proportions on the operational life of the tool, power, productivity:
- It is not recommended to use components that have expired.
- It is especially important for the components of gasoline and oil. Not to use components obtained on the basis of gas condensates, since the molecular structure contains harmful ones, to add water for ICE.
- Partial non-compliance of AI-92 with international standards. Ai-95 brand is saturated with additives that extinguish the detonation moments of ICE.
The noted drawbacks limit in time the operational life of hand-held chainsaws whose ICEs work on complex consistencies of a combustible mixture.
Why do you need to keep the proportion of gasoline and oil?
Many buyers, when purchasing a chainsaw, are puzzled why they should be added in the exact amount to the oil recommended by the manufacturer. It’s all about the intricacies of a two-stroke engine, which differs from a 4-stroke counterpart in a number of specific design solutions.
One of them: the manufacture of a single-cylinder engine, in which there is no crankcase for pouring grease. This is the technological success of his time.
You can imagine how the incoming combustible mixture loses the molecules of oil that settle on the stacks of the cylinder. It subsequently creates a sliding protective film in the rubbing units and parts of the internal combustion engine, reducing the physical contact of the piston rings with the wall of the cylinder, connecting rod and crankshaft.
To provide the unit with maximum performance, long-term operating mode is achieved by the correct ratio of pure gasoline with recommended oil. Violation of the rule guarantees a quick exit of the tool from the functional state. Damage to the internal combustion engine will require significant funds for repair or replacement with a new analogue.
Many users of manual mechanized tools present in the unit oil tank is considered a reservoir for lubrication and power plant. This is fundamentally wrong. The grease is designed for the chain during operation. But only. The oil tank is not a priori connected by a pipeline to the engine.
Rules for the preparation of the mixture
Even experienced lumberjacks do not always make up the combustible mixture for a chainsaw if the work is done in a hurry.
The algorithm of actions is as follows:
- Prepare a plastic container containing 2.5 liters or less;
- There should be a measured container. Many use a regular medical syringe;
- First, fuel is poured into the container, and then a precisely measured portion of the oil;
- The final task is to thoroughly dissolve the oil product by actively shaking the consistency.
When making a mixture of gasoline and oil, one should adhere to the prohibitive action. You should not try to mix it in the gas tank of the tool.
After the finished combustible product is recommended to be stored for 14 days. If more, the oil will settle to the bottom of the tank. A new shake of consistency will be required. People busy with business often forget about this.
How to increase the life of a chainsaw?
A chainsaw will be technically sound under one condition:
When buying a tool, read in detail the instructions and manufacturer’s recommendations for use.
Strictly adhere to and comply with the requirements for the selection of components for the formation of a combustible mixture consisting of gasoline and recommended oil.
It is impossible to use oils intended for motor vehicles to form a working product. This is strictly prohibited.
