The ratio of gasoline and oil for a chainsaw

Regardless of the type of chainsaw, such a tool is driven by a two-stroke engine. It works on a mixture of special oil and gasoline. However, not every user of the equipment knows in what ratio these elements should be mixed, how to properly store the prepared mixture, etc. As a result, many problems can arise during operation, especially if a person has not correctly performed all of the above manipulations.

The ratio of gasoline and oil for a chainsaw

Therefore, for stable and long-term operation, it is necessary to provide the optimal ratio of oil and gasoline for a chainsaw. At the same time, due to high loads and various operating conditions of the equipment, special attention should be paid to the quality of both liquids.

Why add oil to gasoline to refuel chainsaws

The main reason why oil is necessary for the operation of the chainsaw is the safety of the internal combustion engine. Since the main unit is push-pull, it does not have a special oil reservoir. If only gasoline is poured into the tool, then all elements of the system will undergo rapid wear due to lack of lubrication. In such a situation, the chainsaw will fail very quickly. The piston, crankshaft, bearings and connecting rods will be especially deformed. Thus, it is forbidden to use only gasoline for the operation of the tool.

However, there is a feature that is associated with observing the ratio of gasoline-oil for chainsaws. With regard to such a rule, one should know that the wrong proportion, both up and down, can cause system defects. Therefore, immediately after buying a chainsaw, you must carefully monitor the mixture that is poured into the engine of the tool.

Proportions of oil and gasoline for chainsaws

One of the main questions of all chainsaw owners is how much oil per liter of gasoline is in a chainsaw. Most often, mixing the two elements falls directly to the owner of the equipment. It is important to understand that the better the quality of both elements, the more reliable and efficient the mixture obtained.

Depending on the chainsaw model, the ratio may vary slightly. In a standard form on 1 liter of gasoline it is necessary to prepare from 25 ml to 50 ml of oil. However, the value may vary depending on the characteristics of the tool, including power. So, if this indicator is equal to 1.5 kW, then the optimal ratio of gasoline and oil for a chainsaw will be 1 to 25 ml. If the equipment has a higher power, it is recommended to fill in from 30 ml or more. For some Stihl chainsaw models, the optimal amount of oil per 1 liter of gasoline is 50 ml.

It should be noted that more often than not, oil producers indicate on each type of packaging what ratio should be observed when refueling.

When choosing a proportion, it is necessary to take into account the fact that only a purchased tool needs a break-in. With this process, the oil level in the mixture should be 20% higher than the standard value. The same rule applies if the equipment is operated at low temperatures.

A specific mixing algorithm does not exist. In normal situations, gasoline is poured into the container, then oil is added.

Features of the preparation and storage of the fuel mixture

An important step when working with chainsaws is to refuel them. If the proportions were observed, then improper preparation of the mixture can cause new problems. Therefore, it is recommended to adhere to some rules by which it is necessary:

  1. Refrain from using mixing tanks made of plastic or glass, as these materials cause a spark, which in the future can cause gasoline fumes to ignite. It is best to use special aluminum cans for fuel.
  2. Carefully ensure that foreign bodies, debris, dirt and other substances do not get into the tank with the mixture. Negative effects can cause even a few grams of water.
  3. Stir the mixture before pouring it into the chainsaw.

These rules will help people who do not know how to breed gasoline for a Stihl chainsaw or any other brand.

Features are associated not only with the creation of the mixture, but also with its further storage. Do not use oil and gasoline if their contact lasted more than 30 days (shelf life). Such actions will damage the engine system. At the same time, it is not possible to use the warranty for repairs, since such a reason is considered not to be warranty.

If the season when the chainsaw is needed is completed, then all fuel together with the oil should be removed from the system.

Risks of using fuel and oil substitutes

Thus, mixing falsifications significantly worsen the condition and operation of the tool, causing premature breakdowns, in special situations a complete failure.

For this reason, which oil and gasoline to buy should be treated with particular care.

Benefits of Branded Oils

The proportion of oil to gasoline for a chainsaw is not the main factor affecting the stable operation of equipment. The quality of the oil plays an important role, since it will depend on it how much all the elements of the engine system will be lubricated.

It is recommended to purchase liquids from brand names. In this case, the choice must be stopped only on oils for two-stroke engines. It is forbidden to use lubricants for automobile engines to breed fuel.

Brand names, including Husqvarna, Kreissman, Stihl and Sadko, have many advantages, which include:

  • fuel economy;
  • lack of soot;
  • reduction of toxicity of exhaust gases;
  • stable operation under the most difficult conditions.

However, the main advantage is a long service life.

Which oil to use

Oil color

Depending on the manufacturer and characteristics, you can find oils of the following lights:

However, the shade of the liquid does not have any effect on the characteristics and functionality of the oil. The main task of color is to identify one or another manufacturer from the total mass. Therefore, you can pour oil of any color into gasoline. It is recommended to refrain from acquiring products that cause concern due to an unknown composition or manufacturer.

Mineral or synthetic

Qualifying oils for several types can distinguish products of the type:

  1. Synthetic. They have high stability during operation in all weather conditions, maintaining their structure and consistency. over, they have less volatility and greater anti-friction properties.
  2. Semi-synthetic. Mixed type, which is obtained from a ratio of 30 (synthetics) to 70 (mineral). Therefore, the quality of such a lubricating element is at an average level.
  3. Mineral. The disadvantage of this oil is working only in warm climates. In extreme cold, the mixture quickly solidifies, adversely affecting the operation of the instrument.

However, experts recommend using a two-stroke engine or mineral oil or semi-synthetic. They are distinguished by stable characteristics and low price. However, before choosing the optimal type of oil, it is important to consider the further operating conditions of the chainsaw. So, for example, for home use, it is better to opt for mineral or semi-synthetic oil. To work on an industrial facility on a larger scale and in difficult climatic conditions, it will be optimal to purchase synthetic lubricants for chainsaws.

Another factor is the characteristics of the equipment and the advice of the manufacturer.

Which gasoline to use

At gas stations you can find different types of fuel. Each of them has its own cost and technical characteristics, including special additives in gasoline. However, not every brand is suitable for a chainsaw. In order not to spoil the equipment and ensure optimal operation, it is necessary to fill the fuel above 92. Some experts note that, due to the poor quality of the Russian fuel and lubricants, 95 should be used instead of 92.

Another rule of proportion of oil and gasoline for chainsaws is associated with leaded fuel. Choosing this type of fuel is strictly prohibited, since it increases the failure of the engine and its components.

What will happen if you do not take into account the recommendations

An inexperienced person does not know how to dilute gasoline with oil, how to choose the right fuel, what proportion of gasoline to use, and many other nuances. Often, such ignorance leads to the appearance of a large number of problems in the operation of equipment:

  • increase in fuel consumption;
  • defects in the unit and its components;
  • the appearance of extraneous noise;
  • toxic emissions, etc.

Therefore, experts recommend adhering to tips related to all aspects of equipment operation, starting from how to choose the right fuel, ending with how to dilute gasoline for a chainsaw.
