The proper knowledge of refueling a chainsaw tank is necessary to make it last longer. Not only the knowledge but the right type of fuel mixture is also required. The internal sections of the engine are lubricated by mixing oil with gasoline. The internal components will seize up without oil in the fuel tank. Even the most advanced chainsaws need to be adequately fueled. So how to mix chainsaw gas properly? Follow the instructions given in this article.
How To Mix Chainsaw Gas – Step By Step Guide
Before starting to mix chainsaw gas and oil, make sure of the following things:-
- Petrol is another word for gas. Don’t get confused.
- American weights and measure system is different than the rest of the world. Therefore while reading the manual, double-check the metric units mentioned. Then they should be converted accurately. If there is something wrong with the measurements, the whole process will be a failure. So make sure that you take the measurements accurately.
You must also have idea about the types of fuel used for chiansasws
The life of the engine of a chainsaw is directly proportional to the quality of the gasoline you use in it. Cheap stuff can also harm the engine. An octane rating of 89 is recommended for your ethanol-free petrol. Using fuel with a lower octane rating will increase the temperature of the engine. This increase in temperature can damage the internal parts permanently. Make sure that you don’t mix chainsaw gas that contains ethanol.
You can not use regular motor oil in your chainsaw. A 2-cycle chainsaw needs a special type of oil. Regular oil lacks several properties. To lubricate a 2-cycle engine, you need these properties which the motor oil lack. So, always buy a 2-cycle, two-cycle, 2T, or a 2-stroke oil.
Approved Containers That You Can Use
The mixing chainsaw gas and oil needs to be done in an approved storing fuel container. You can not use milk jugs, anti-freeze jugs, or glass containers to store gasoline. The non-approved containers are not compatible with the chemical properties of gasoline. They can’t hold the expansion and contraction pressure, which is induced by the variations in temperature. Underwires Laboratories and Factory Mutual offer the best containers for handling gasoline. You can buy a container from either of them.
Follow the steps given below to mix chainsaw gasoline:-
Total Time: 45 Minutes
Gather the following items
1. UL or FM approved container
2. 89 octane or higher ethanol-free gasoline ( 1 gallon)
3. 3-ounce bottle or more of 2-cycle oil
Pour half of your gasoline in an approved container.
Pour the required amount of oil for chainsaw’s 40:1 or 50:1 mixture in the approved container. Then close it and shake it for 10 to 15 seconds.
Pour the rest of the gasoline in the approved container. Now, shake the container again for 10 to 15 seconds.
Now, pour the gas and oil mixture in the chainsaw’s fuel tank. Keep pouring it until it’s 80% full. Once it’s 80% filled, tighten the cap and wipe any spillage away.
Mixing Ratio Chart
Every chainsaw is designed differently. Each chainsaw engine needs a particular fuel ratio to run the oil mixture. 40:1 and 50:1 are the ratios frequently used. Refer to the following chart for the correct measurements.
40:1 Gas Oil Mixture Chart
|Liters of Gasoline||Liters of Oil|
|3.78 L||0.94 L|
|7.57 L||0.189 L|
|11.35 L||0.28 L|
|15.14 L||0.37 L|
|18.92 L||0.47 L|
50:1 Gas Oil Mixture Chart
|Liters of Gasoline||Liters of Oil|
|7.57 L||0.15 L|
|11.35 L||0.23 L|
|15.14 L||0.30 L|
|18.92 L||0.37 L|
Tips On Mixing Chainsaw Gas
- The knowledge of the accurate ratio is mandatory. Any mistake while mixing will damage the machine.
- The chainsaw should always be cooled and turned off while refueling it with fuel.
- Don’t turn on the machine when there is fuel spilled around you or on your clothes.
- Avoid smoking while working with gasoline and oil.
- You should always mix chainsaw gas in approximate amount. The stale gas can clog the carburetor during operation. It spoils with time. Varnish deposits are formed if you keep it for too long. So it is recommended to mix chainsaw gas according to work required at the moment.
- Keep operating the saw until the fuel in the tank is consumed. Leftovers should not be left inside the tank. You can always store the leftover mixture in the approved containers.
- Though the mixture is best to be used within 30 days, you can still store it for three months.
- You should never directly combine the oil and gas in the chainsaw tank. Use containers by “Underwires Laboratories” or “Factory Mutual.”
1. Can different brands of chainsaw gas be mixed?
No, mixing different brands of gas can damage your machine.
2. What will happen if I use regular gas in my chainsaw?
Regular gas can damage and ruin the piston and crankcase. It will damage them within the blink of the eye. Never use regular gas in your chainsaw?
3. What is 50 to 1 mixture?
2.6 ounces of oil are needed for one gallon of gasoline in a 50:1 mixture.
4. Name the best gas to use for a chainsaw.
Stihl, and Husqvarna are the high octave unleaded gas, which is best for a chainsaw.
5. Can I use old gas for my chainsaw?
No, don’t risk damaging your machine to save a few bucks. Always use fresh high octave gas.
Now you know the correct measurements for the ratios to mix chainsaw gas. You should neither mix different brands of gas nor use a regular gas for your chainsaw. They can damage the engine and decrease the life of the machine. Stihl and Husqvarna are the best high octave gases that you can use. Don’t use the mixture, which is more than three months old. It is recommended to use the mixture within a month. Make sure you never dump your gas on the ground. It is not only illegal but can be very dangerous as well. Your chainsaw will start quickly and run better if you follow all the instructions correctly.
