Hello

Does 92-3 octane fuel in the 3.6 engine
Improves engine performance?
Does prolonged fuel refueling 93 octane cause damage?

Thanks

The best way to get more mpg is to run fuel with no or lower ethanol %. Usually high octane meets this criteria and why you see better fuel mileage. However the $/mile is usually a wash at most.

With that said not sure how octane is measured where you are and how much ethanol is typically used. In the states we are usually 10-15%.
