We all are aware of the importance of filling the fuel tank of the chainsaw with the right kind of fuel. Using inaccurate or unproportionate fuel compositions in the chainsaw will only result in consequences for you to suffer. 

No chainsaw is ever to be run on straight gas because it significantly damages the engine of the chainsaw. Every user of a chainsaw is always advised to add fuel with a composition of ethanol and octane in the gas mix. 

Straight gas here means pure gas with no other fuel or liquid mixed in it. With this being clarified, we will proceed to what happens when you run straight gas in a chainsaw. 

What Happens When You Run Straight Gas In A Chainsaw?

It is evident that when you mess around with something, all that would come out of the situation is consequences.

So is the case with using straight gas in a chainsaw. Following are the problems you will have to face when running straight gas in a chainsaw! 

Engine Will Heat 

What happens with a mixed fuel that is not straight gas, it keeps the chainsaw piston lubricated within the cylinder that it is found.

This means with a mixture of fuel; the piston will keep performing its function of moving up and down without any hindrances, maintaining its incredible speed.

 

Even when high friction levels develop due to the constant movement, the mixture of the fuel ensures that the friction is calmed down and kept to a level whereby the chainsaw will not stop working. 

However, with running the chainsaw on straight gas, there will be no fuel in the chainsaw working to counter the built-up friction in the machine.

As a result, the engine will heat up severely, and the fuel will keep igniting, powering the piston, but it will also start to burn, eventually causing the piston to fail. 

Piston Will Seize 

As there is an absence of oil in straight gas, there will be no liquid present in the fuel that would prevent the gas from burning at an exceptionally increased temperature. Hence, causing the piston to seize.

 

Metal making the piston and the cylinder will be greatly expanded due to constant exposure to the heat. No fluid will be going inside the cylinder, assisting it to moving. 

Subsequently, the friction that would be within the cylinder would eventually result in the piston seizing and stopping moving altogether. Additionally, the crankcase will stop turning beneath the piston, and when the crankcase stops moving, the system will lapse. 

Damage To The Engine 

When straight gas continuously burns inside the engine of the chainsaw, bit by bit, the engine is eventually damaged. The already seized piston will be incapable of moving, and the crankcase that was previously turning will no longer turn. 

While you can easily remove the crankcase and piston and replace them with the installation of a new spare part, it is very unlikely to do this when you have been running your chainsaw on straight gas.

 

This is because as the metal was constantly being heated due to the straight gas, it would have burned and caused the metal of the crankcase and the piston to corrode. Therefore, making the replacement of these parts an arduous task to perform. 

Supposedly, if you consider replacing these chainsaw parts, it will be very costly. Rest assured, the amount you will spend on replacement can be the amount in which you can purchase a brand new chainsaw. This is how costly it is! 

Conclusion 

Now that you are well aware of what happens when you run straight gas in a chainsaw, we hope you do not even consider the possibility of using straight gas in your machine. Always and without a second thought, you must use a combination or a mixture of fuel in the chainsaw because without it you are bound to face the consequences.
