Why do chainsaws need to be filled with a mixture of gasoline and oil?
Why is it contraindicated to fill the unit’s tank with gasoline without oil, and what happens if you make a mistake? The reason for the need to dilute gasoline with oil is that two-stroke engines do not have an oil chamber, like four-stroke engines. The absence of this chamber leads to the fact that the rotating and rubbing metal parts of the engine do not receive lubrication, so the following disadvantages are observed:
- The friction force increases, which means rapid wear of parts.
- The temperature increases due to the friction force, which also negatively affects the operational life of the internal combustion engine.
- As the load increases, there is a significant loss of power and performance.
Oil is added to the gasoline of a chainsaw unit to prevent the development of the above processes. If you pour pure gasoline into the tank of the unit and start the engine, then in a short period of time it will simply overheat and jam. That is why, when purchasing a tool, it is important not only to find out how to start and operate a chainsaw, but also to understand the ratio of gasoline to oil.
How to adjust the oil supply to a chainsaw chain?
Adjusting the oil supply to the saw element is required in cases where the tool was susceptible to complex repairs such as replacing the piston group, fuel pump and other important mechanisms. Adjustment is also required as a result of mechanical damage to the saw.
To adjust the oil supply on a chainsaw, you need to find an image of an oil tank on its body. Next to the image there is a screw that needs to be turned.
The adjustment is performed in this order:
- Start the chainsaw and let it idle;
- Place the saw on the old newspaper;
- Insert a flathead screwdriver into the screw and begin to slowly turn it clockwise until small drops of oil appear under the saw;
- If too much oil drips from the chain, its supply must be reduced. To do this, turn the adjusting screw counterclockwise.
Do not forget to check the oil supply to the chainsaw chain, as its absence will lead to premature wear of the small gears inside the tool.
Why you need to adhere to the appropriate proportions when mixing
Having decided on the need to mix gasoline with oil in a chainsaw, you will need to find out why you need to adhere to the appropriate proportions when mixing the fuel mixture into a chainsaw.
- If you fill in gasoline with a low oil composition, this will contribute to the development of all of the above consequences - engine overheating, scuffing of the CPG and jamming of the internal combustion engine. Only in this case the internal combustion engine will work a little longer than on pure gasoline.
- If you fill the tank with fuel with a high oil content, then this is also dangerous, because in this case, in addition to strong smoke, carbon deposits will be observed on the cylinder walls, muffler and other parts. There will be a decrease in power and a decrease in the productivity of the unit. In this case, the engine will run longer, and if deposits occur, they can be removed.
To eliminate negative consequences, and at the same time increase the service life of the tool, it is recommended to understand how much oil should be added to gasoline for a chainsaw in order to achieve ideal engine operation.
Oil is not supplied to the chainsaw chain
Many chainsaw owners do not know why oil does not flow to the chainsaw chain. This is one of the most common breakdowns of chainsaws, to eliminate which you will have to completely dismantle the oil system of the tool and inspect the filter. If the filter is clean, you will need to pay attention to:
- Is there a break in the oil hose - if it is damaged, it will need to be replaced;
- Is there a thread on the oil pump shaft?
- What is the condition of the thread of the pump drive gear, are there any defects on it;
- Is there a blockage in the line? In this case, blowing the channels with compressed air will help;
- The presence of a main shaft corkscrew - if it is missing, then you can insert a regular nail in its place, shortening it to the required size.
In any of the above cases, replacing the faulty element will help. At the same time, the sooner you change the old part, the better for other elements and mechanisms of the chainsaw.
What gasoline is suitable for the tool?
There are different opinions among sawyers regarding the use of appropriate gasoline. Some recommend using AI-92 fuel, others argue that you should use fuel with an octane rating of AI-95.
Now it's time to dot the i's. All chainsaws operate on gasoline with an octane rating of 90 to 95. However, it is recommended to give preference to AI-92 fuel. The exception is when the manufacturer makes a recommendation about which gasoline is best to use.
Interesting to know! To produce AI-95 gasoline, most manufacturers use additives mixed with AI-92.
The most important requirement when using fuel is that it must be clean and free of contaminants.

. What kind of oil is used to lubricate the chain?
Chainsaws. A popular tool for those who deal with numerous household chores. They can be used for different purposes. collect firewood, trim dry branches. But in order for the device to last as long as possible, it is necessary to take proper care of it by choosing the right different connections. A special role is played by chain saw oil, which is selected depending on the principles of the tool and its characteristics.
What to count?
Proper care should be taken when lubricating chain saws. , you should choose special oil that will not damage the oil pump
In addition, this will ensure high-quality operation of the self-lubricating system. The chain requires proper storage, i.e. immersion in oil, and if worn, do not attempt it. it is easier to replace. What is the best chain oil that is safe and meets all requirements?
Types and composition
The choice of specific oil depends on where and how the chainsaw operates. Mineral compounds are suitable for the summer and warm seasons. In other cases, it is better to use synthetic or semi-synthetic oils. If it is necessary to lubricate the chain, there is no need to use waste oils, which will clog the fuel system and then cause serious damage to the tool.
The chainsaw oil must be thoroughly cleaned to ensure that the lubricant is applied correctly and accurately. If you use poor-quality connections, there will be no contact between the saw elements and the bars, sparks will appear, and then the moving parts of the saw will wear out.
How to choose?
Each chainsaw has a two-stroke carburetor engine and two tanks: one filled with gasoline, the second. oil. When choosing a lubricant composition, zoning plays an important role. it should be minimal. Another important indicator is resistance to low temperatures: the oil should not freeze at extreme temperatures, which will ensure the quality of the entire tool.
For lubrication, it is recommended to use adhesive chain oil containing special substances that allow the composition to adhere well to the chain. High-quality oil will remain on the chain as it rotates, and the chain itself will be more reliable in operation.

Another important indicator of a lubricant is density: if the composition is liquid, it will be consumed in large quantities
To avoid harm to the environment, it is important to use vegetable oil when using a chainsaw. its waste will decompose in the natural environment
Which chainsaw oil should you choose because modern manufacturers offer a wide range of options? Among the specialized manufacturers, we can mention such brands as Divinol, Bio-Kettenol, Ravenol, VegOil, Mobil, Castrol, Shell. Let's take a closer look at the features of their products.

into a chainsaw. Always keep an eye on.
The ratio of oil and gasoline or how to remember the proportion
The most correct proportion of gasoline to oil is the value indicated by the manufacturer.
If you bought a chainsaw, don’t be too lazy to open the instructions and find the manufacturer’s recommendation on how much oil per liter of gasoline to mix into the chainsaw. These recommendations are present in the technical documentation for the unit. However, many people often lose the instructions, so they have to turn to friends or the Internet for help.
If you don’t know how much oil to add to gasoline when preparing fuel, then you should use universal data. Such data requires compliance with the following ratio - 1 to 50 or 1 to 40.
What does this mean? Let's look into this in detail.
A proportion of 1 to 50 means that for 1 liter of gasoline you need to add 20 ml of oil. A ratio of 1 to 40 is characterized by the use of 25 ml of oil per 1 liter of gasoline. Why are two universal values specified? It all depends on the time of year, so if the tool is used in the summer, then 20 ml of oil is added per 1 liter of gasoline, and if in winter, then 25 ml. It’s easy to remember this proportion; to do this, you can use a marker to write marks on the plastic body of the instrument. Below is a table of the ratio of oil and gasoline for chainsaws. Ratios of 1 to 35, 1 to 30 and 1 to 25 are appropriate for high-power units.

Aspects of the device and how to thread the saw
Now we will “plunge” into the very core of this tool, so that you can at least have a general idea of what your “assistant” consists of. In fact, this kind of tool can be responsibly attributed to classical mechanisms that operate by activating an internal combustion engine.
Two stroke engine
Without exaggeration, we can say that this type of tool is the simplest of all other mechanisms , since the saw does not have a gearbox and is equipped with a conventional two-stroke engine, which has one cylinder and runs on gasoline.
The main advantage of a chainsaw is that it is designed quite simply, which helps to increase reliability, as well as trouble-free operation in difficult and difficult conditions. Next, let's look at the design of the saw in more detail, so:
- engine;
- clutch;
- ignition system;
- carburetor (see carburetor adjustment);
- fuel system;
- air purification system;
- starter;
- chain (see how to sharpen a chain);
- tire;
- chain brake;
- chain tension mechanism;
- chain lubrication system (see chain lubrication oil).
In essence, we have sorted out the device, but now an important issue remains the lubrication of the chainsaw parts. Many people do not understand why it is needed at all? The answer is quite simple, like all mechanisms, a chainsaw, especially its individual parts, require special care, including periodic lubrication.
This is necessary in order for your tool to serve you for many years , since during operation, the chainsaw spare parts produce a movement that must be smooth, smooth, so as not to damage nearby spare parts.
Just as everyone knows that the friction force disrupts the surface, so here, if you do not lubricate the chainsaw as necessary, the spare parts will simply wear out quickly and the tool will fall out of tune. You need it? Don't think. Therefore, it is necessary to take care of your chainsaw so that it “has the strength” to serve you for many years.
When choosing a chainsaw, you need to focus on your needs and what you want to use it for.
If you need to take it into use, then choose a mini chainsaw.
For woodworking, saw blade sawmills are better suited.
Instructions for making a fuel mixture
Let's find out in more detail how gasoline is diluted with oil. Some tool owners do this - pour clean gasoline into the tank and add the required amount of oil. After this, close the lid and stir. This method of diluting gasoline with oil is incorrect. Instructions for preparing a gasoline-oil mixture are as follows:
- You need to take a plastic bottle of equal volume - 1 or 2 liters. You can use a 1.5 liter, but this can cause confusion when adding oil.
- Fill the container halfway with gasoline.
- Add lubricant. It is recommended to dose the oil using a syringe. It is advisable to use a 5 cc syringe, which will allow you to measure exactly 25 ml of oil.
- After adding the lubricant to the container, shake thoroughly.
- Add gasoline until the container is full and mix thoroughly again.
- The result is a ready-made gasoline-oil mixture for a chainsaw, which should be used within 1-2 weeks.
Many people do not pay enough attention to storing the prepared mixture, and therefore can immediately prepare 5 liters and use it throughout the year. However, this approach is extremely incorrect, since the shelf life of the finished mixture is 15 days. If you are sure that gasoline does not contain alcohol, then you can store the finished mixture longer - up to 3 months. After this, the mixture loses its properties, having a negative effect on the internal combustion engine.
Interesting to know! Make it a rule not to prepare chainsaw fuel in large quantities. It is better to prepare 2 times one liter, than to immediately mix 2 liters, which will remain and will be stored indefinitely.
After combining gasoline with oil, all that remains is to refuel the tool and start using it. When refueling a chainsaw, there are some important points that should be taken into account. We'll look into them.
Storage recommendations
The mixture must be prepared in the quantity necessary to carry out a small amount of work, since when the solution is stored for a long time, its quality characteristics deteriorate. The prepared mixture must be consumed within several days.
A fuel mixture that has been stored for about a month will reduce engine performance. Resinous substances are formed in the nodes, and carbon deposits appear, the piston rings lose mobility. The longest shelf life of the mixture is no more than 2 weeks. During this period, the solution will not lose its quality. If the air temperature is more than +25ºC, then the shelf life of the product is reduced to 10 days.
Some experts allow the use of expired mixture to save money. To do this, it can be spent gradually, gradually mixing it into a fresh solution in a volume of no more than 10% of the total amount of the mixture. The finished gasoline-oil mixture must be filtered.
If you follow all of the above recommendations, you can ensure reliable operation of the chainsaw. Also, when performing work, you must observe safety precautions, since the chainsaw operates using a chain that rotates at high speeds and, if operating rules are violated, can pose a danger to the worker himself and the people around him.
How to properly fill a chainsaw with a gasoline-oil mixture
Freshly prepared mixture should be stored in a dark room, but no more than 2 weeks. It is best to mix immediately before using the tool. The refueling procedure is carried out by performing the following manipulations:
- Before unscrewing the tank cap, you need to clean the surface, or even better, blow it with a hose from the compressor.
- Place the chainsaw on its side with the lid on top. At the same time, keep in mind one important point: refueling should not be done in the wind in order to prevent dust and other contaminants from entering the tank.
- Place a watering can on the neck, which will eliminate the possibility of fuel spillage.
- Fill the tank, but do it so that there is room left. This is done in order to eliminate the possibility of gasoline leaking when screwing on the cap.
- After refueling the chainsaw, be sure to pour oil into the tank to lubricate the chain.
We start the engine and make sure it is functioning properly. The smoke from the chainsaw should come out light in color and in volume only when the speed increases.
