Re: Regular, Super, or Premium Fuel? Thoughts?
It's a well proven fact that an engine designed for low octane gas will loose some power using high octane.
High octane only means the gas burns slower and the engine needs advanced timing and higher compression to get any advantage.from more octane.
You can even cause pre mature damage to the engine because the fuel is still burning during exhaust stroke, making valves and or exhaust ports hotter, also a waste of fuel to have it exit the engine before applying most of it's energy to the piston.
This has been proven by dyno tests on Ducati bikes, I know that for sure.
