How to choose chain saw oil

Oil for two-stroke chainsaw engines should be chosen according to more stringent requirements. Experts recommend using a mineral or semi-synthetic lubricant, which is designed for 2-stroke engines that are used at high revolutions.

The advantage of using mineral chainsaw oil is its low price. Synthetic fluids are more expensive, but have improved quality indicators and meet European standards.

Synthetic oils can be used under big temperature fluctuations, they do not create soot deposits, contain additives useful for engine work.

Motor oil is produced by a large number of manufacturers, both foreign and Russian. The best quality oils are Husqvarna oils. In some characteristics the branded products are inferior to the domestic Lukoil brand oil.

The advantages of branded products are:

  • economical consumption;
  • Preservation of quality during prolonged storage or operation under adverse conditions;
  • Small amount of toxins;
  • no fouling.

Professional and consumer saws use oils prepared according to American API-TB technology. The Japanese JASO-FB analogue of these products is also used. Do not use a fluid that was created for 4-stroke engines to make a mixture.

The color of the oil, e.g. green, red, indicates that the product is produced by a certain company. When selecting the indicators and characteristics of the product, color is not taken into account. Care should be taken when selecting a motor oil whose manufacturer and composition are unknown.

Until additional information about performance and quality is available, it is best not to use this oil just yet. It is possible to mix motor oils that have the same characteristics of purpose and composition, which are products of famous brands and are of high quality. Mineral and synthetic oils should not be mixed.

A wide variety of chainsaw oils are available in stores. A large number of products allows you to use oil for a chainsaw, which corresponds to the class and indicators of the design, as well as the conditions of its application. For inexpensive chain saws it is better to use motor oil of the Standard category. For professional modifications the lubricant Ultra is designed.

To prepare a quality mixture, it is necessary to use those brand oils or their analogues, which are recommended by the instruction manual of the chainsaw. For example, Husqvarna and STIHL fuel and lubricants can replace one another.

Experts do not advise to use a lubricant in the gearbox for chainsaws, which is produced for 2-stroke engines of mopeds, motor boats. Their engines are used in softer ambient conditions that they have lower quality requirements.

Which oil and gasoline to choose for filling lawn mowers with a two- or four-stroke engine

Lawnmower oil coats rubbing parts and gaps between parts with a thin, binding film, resulting in less wear and tear and reduced surface scuffing and scratching during operation.

Preparation, mixing and changing the fuel-air mixture are the main maintenance procedures for lawn mowers. The quality and composition of the fuel and lubricant used determines the durability not only of the rotating parts but also of the engine.

Lawnmower oil covers rubbing parts and clearances between parts with a thin binding film, thus reducing wear and scratches in operation.

How to Choose the Right Fuel for Your Mower

Fuel mixture proportions

If the mixture is diluted correctly, for example by following the instructions below, the equipment will serve you for many years without serious technical failures. In this case the fuel consumption will be low, and the result of the work will be high. The fuel mixing process must always be uniform and constant. It is always better to use the same ingredients, without changing the brand specified by the manufacturer.

You should not add much oil, it can damage the engine, but you should not economize on it either. To maintain the correct proportions, always use the same measuring jug so you never make a mistake with the amount. You can use medical syringes to measure the oil, but some manufacturers also provide measuring containers with dashes together with the oil.

The most correct ratio of oil to gasoline is 1 to 50, where 50 is the amount of gasoline and the amount of oil is 1. For better understanding, 1 liter equals 1000 ml. So, to get the proportion of 1 to 50, we divide 1000 ml by 50, we get 20 ml. As a result, you only need to add 20 milliliters of oil to 1 liter of gasoline. To dilute 5 liters of gasoline, you need 100 ml of oil.

In addition to observing the correct proportion, you must also observe the technology of mixing the ingredients. Never simply add oil to the gas tank. It is better to follow the following step-by-step instruction.

  • To dilute the mixture, it is necessary to prepare in advance a container in which you will mix gasoline and oil. This can be a clean metal or plastic canister with a capacity of 3, 5 or 10 gallons to make it easier to count the amount of oil. Do not use drinking water bottles for this purpose. they are made of thin plastic that can be dissolved by gasoline. To measure the oil use a special measuring container. But if there is no such, then, as already noted, medical syringes with a large dosage will do.
  • Pour gasoline into the canister, without adding a couple of centimeters to the full volume. To avoid spilling gasoline, use a watering can or put a funnel in the mouth of the canister. Then pour the right amount of oil into a syringe or measuring device and pour it into the container with gasoline. It is not recommended to do the opposite. pour gasoline into the oil.
  • Close the cap tightly with a bottle and stir the mixture. If a part of the fuel spills during the mixing or mixing process, you need to wipe the canister immediately with a dry rag.
  • Fire precautions must be strictly observed. Dilute the mixture away from the fire, and in no case leave the fuel residue and used materials inaccessible to children.

One more important thing: it is better to mix just the right amount for your brushcutter’s fuel tank. It is undesirable to leave any remains of the mixture.
