How much oil is in the chainsaw in the engine
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.
- 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.
How to Add Bar and Chain Oil to Your Gas Chainsaw
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.
Stricter criteria for the selection of the oil component. In the best variant, it is a mineral or semi-synthetic engine oil recommended by the manufacturer, intended for operation in high-speed two-stroke air-cooled internal combustion engines.
The advantage of mineral oils is their lower cost. Their more expensive semi-synthetic and synthetic counterparts are distinguished by improved performance and compliance with environmental standards.
- maintain working properties in a wide range of operating temperatures;
- do not form carbon deposits;
- contain detergents, antioxidants, preservatives and other additives useful for the operation of the power unit.
Risks of using fuel and oil surrogates
To avoid premature failure of the chainsaw, it is recommended to refuel the tool with exclusively high-quality and branded consumables. Finding such materials is not difficult, as they are usually sold in branded retail outlets. The use of low-quality gasoline can lead to engine failure, therefore, it is recommended to buy fuel at such filling stations where high-quality fuel is guaranteed.
It is categorically contraindicated to mix gasoline with motor oil for cars, since it is not at all intended for such purposes. Compliance with the number of proportions, as well as the use of high-quality materials will extend the life of your tool for many years.
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 enter the carburetor. As a result, you will have to disassemble the engine and wash it.
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 rubbing parts of the mechanism. When running in a new tool, it is advisable to add twenty percent more lubricant. It is recommended to dilute with a large amount of oil in areas with high air temperatures.
Many owners will be interested in information on how to dilute gasoline with oil if there is no measuring container. A twenty cc medical syringe is suitable for this. Although most often measuring containers are included in the kit for chainsaws.
The neck of the gas tank must be cleaned and degreased before diluting the fuel. It is advisable to pour it through a filter. Any rag will serve as a filter.
After use, the remaining mixture must be drained and disposed of. Remember 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 render the tool inoperative. For example, if the fuel is not diluted, then carbon deposits will form more often, the necessary lubrication of the pistons will not occur, as a result of which the temperature in the engine will rise. This will cause the pistons to break. Or the owner of the saw will inhale large quantities of toxic fumes throughout the entire operation. Thus, he will earn health problems, break the instrument.
Chainsaw Leaking Bar Oil All Over The Place Repair
If you use poor quality lubricants and fuels, they can also damage the engine. It is not recommended to dilute engine oil made for automobiles. Fuel must be purchased with a high octane rating.
Gasoline and oil for chainsaws. which is better
Often beginners ask, which one is better to take gasoline for their instrument? In order not to make a mistake in the choice, it is recommended to read the instructions for the tool. In the instructions, each manufacturer indicates the corresponding brand of fuel. If the manufacturer indicates that the octane number should not be lower than 95, then it is not recommended to pour 92 gasoline.
Motor oils for two-stroke engines are produced by the following manufacturers:
Usually, the ratio is indicated on the lubricant bottle, so it will be difficult even for beginners to get confused with the preparation of the fuel mixture. Do not under any pretext use the working off even as a chain lubricant. This will lead to the fact that soon it will be necessary to repair the tool.
Ratio of oil and gasoline for chainsaws
How much oil to add to gasoline for a chainsaw is indicated, first of all, in the operating instructions for the tool. If you have forgotten what the proportion of oil and gasoline should be, then you can always open the instructions and update your knowledge. If the instructions are lost, then this material will help you. To begin with, it is worth noting that there are several options for mixing oil materials with fuel. Choosing any, it is worth noting that the main criterion for each is the correctness of measuring the components. Only the exact observance of the proportion of oil and gasoline will allow achieving the fuel mixture of the required technical qualities.
One of the most common proportions is 1:50. This means that 1 liter of gasoline must be diluted with 20 ml of oil. Such a recipe for preparing a mixture is relevant for tools whose power exceeds 1.5 kW. This option is one of the most popular, so if you have forgotten the exact proportions for your instrument, then you can always focus on the first option.
The second option provides for a ratio of 1:25. Mixing 1 liter of gasoline with 10 ml of oil is recommended by Chinese manufacturers for their tools. For tools whose power does not exceed 1.5 kW, it is recommended to pour oil in the amount of 25 ml per 1 liter of gasoline. Each manufacturer’s chainsaws have their own restrictions, and recommendations for preparing a fuel mixture, which are recommended to be followed. The above are two main options that are universal.
It’s important to know! An excessive amount of the oil mixture in the fuel is also negative, since this will lead to a reduction in the engine resource due to increased shock loads on the cylinder and piston, and will also entail the formation of carbon deposits.
Not everyone knows what kind of gasoline to pour into the chainsaw. This is also indicated in the technical documentation for the chainsaw. In modern saw models, it is recommended to pour fuel of a grade not lower than AI-90, that is, AI-92 or AI-95. And it doesn’t matter who the tool manufacturer is, China or Europe. Professionals recommend using AI-92 gasoline, since in Russia the 95th is in most cases produced from 92 by adding additives. If you know for sure that this is really pure 95, then it is better to use it.
Many craftsmen continue to pour gasoline of grades lower than AI-90 into modern models of chainsaws, as it was allowed to do this for outdated models of tools: “Friendship”, “TAIGA” and others. This is not recommended.!
Which oil to use to lubricate the chainsaw chain depends directly on the model of the tool. STIHL branded saws and the like produce special lubricants that are intended only for use in such tools. Recommended oils can also be found in the technical documentation. When choosing a lubricant, you must pay attention that it is necessarily intended for two-stroke engines. Oils for mixing with gasoline and for lubricating chains differ in composition, quality and purpose. You cannot mix them, as this will accelerate the failure of the instrument. Recommended oil brands for two-stroke engines:
It is better to prepare the mixture in an amount that should be enough for one-time work. The problem lies in the irreversible deterioration of the working properties of the mixture during storage. The finished composition is recommended to be used over the next few days.
A mixture of gasoline with a month-old oil impairs the traction capabilities of the engine. There is also the formation of resinous compounds in the fuel system and intense carbon formation in the combustion chamber, loss of mobility of the piston rings.
Chainsaw not oiling? Check this FIRST!. Homestead Tips
- With minimal damage to quality, it is advisable to store gasoline with oil for no more than 2 weeks. At an ambient temperature of 25 degrees Celsius or more, this period is reduced to 8-10 days.
- In order to save money, the expired mixture can be gradually consumed by mixing it into the fresh composition in an amount of no more than 10% of the total volume.
In order to avoid problems associated with the failure of the fuel system, it is recommended to filter the prepared mixture through a non-fiber material such as suede, or a fine-mesh twill weave, a metal mesh.
Features of preparation and storage of the fuel mixture
Safety regulations prescribe to dilute gasoline and oil in a metal canister. This eliminates the risk of static electricity and fuel ignition.
Experts advise to pour oil into an incomplete container, mix thoroughly, and then top up with clean gasoline to the specified level. Saving working time by preparing the working mixture directly in the gas tank of the chainsaw should be excluded from everyday practice.
This technology is fraught with fuel system failures due to the ingress of a large amount of oil into the carburetor, the need for disassembly and thorough flushing.
