The gas/oil ratio for a chainsaw is 25 to 1.
Most chainsaws are built with 2-cycle engines which require a mixture of fuel and oil to run.
Oil and gasoline are mixed.It needs petrol to lubricate the internal parts of the engine.The internal components would seize up if there was no oil in the fuel tank.
Before I show you how to mix chainsaw fuel, I want you to know that I have several chainsaw buying guides to help you find the right tool for your needs.
These posts can help you find a chainsaw or upgrade your machine.Each one shows you what the top features are to look for in a particular type of chainsaw and offers reviews of the best products you can buy today.
The life of the engine is dependent on the quality of gasoline you put in it.
Fuel with a lower octane rating can cause damage to the internal parts of the engine.
If you mix regular motor oil with a 2-cycle engine oil, it will degrade the chainsaw's performance because it lacks several properties needed to lubricate the engine.
Make sure the oil you buy says "2T" on the container.
An approved container is needed for storing fuel when you mix gasoline and oil for your chainsaw.
Milk jugs are not suitable for carrying or storing gasoline.The chemical properties of gasoline are incompatible with non-approved plastic.The containers are not strong enough to cope with the pressures of expansion and contraction caused by temperature changes.
The best containers for handling gasoline are Factory Mutual approved safety cans.Make sure that the container you are mixing your chainsaw gas in has either of these approvals stamped on it.
50 to 1 gas oil mixture is what your chainsaw will take.You can get the details from your product manual.You will find out how to mix these ratios later in this guide.
Put all of the oil in your chainsaw.The charts on how to achieve these ratios are listed after the steps.
Remove the fuel tank cap from your chainsaw and pour the gas and oil mixture into it.
Each chainsaw engine requires a specific ratio of gasoline to oil mixture to run.
The charts below will show you how much fluid is needed to get the right gas to oil ratio for your chainsaw.
