Everyone says premium fuel is a waste of money in these things but I am wondering if the lower octane fuel is part or all of the problem, any thoughts?
I did not read any of the posts but if you are not running the lowest octane fuel you can buy you caused the detonation.
High octane in fuel is there to make the fuel HARDER to burn. Designed for higher comression engines which you do not have.
Fuel with higher cetane
burns easier but the gas companies control that chemical additive.
