About Chainsaw Fuel Mixture About Chainsaw Fuel Mixture

Unlike fuel for your car or lawnmower, chainsaw fuel needs to be mixed before it can be used. Thankfully mixing chainsaw fuel is easy to do once you know what needs to be added to make the fuel mixture

Why a Fuel Mixture?

Because chainsaws use a 2-stroke engine rather than a 4-stroke engine like most automobiles, a special fuel mixture is needed in order to lubricate the moving parts of the chainsaw engine.

What Is in Chainsaw Fuel Mixture?

Oil is added to the gasoline in order to lubricate the moving parts of the engine. There is a certain ratio needed to the chainsaw mixture for it to work. While the most common ratio in the United States is 50:1 gas to oil, this can vary depending on the make and model of your chainsaw. To be 100% sure of the ratio, check your owner's manual or check with the manufacturer.  It’s important to get the ratio right so that your chainsaw continues to work and the engine doesn’t seize up.

Replacing Your Chainsaw Fuel Line

Sometimes your fuel line can break or become cracked and it will need to be replaced. This is something that you can easily do yourself by removing the broken line and then threading the new line back in.
