How Does Gasoline Grade Affect Performance?
Higher grade/octane fuel can give you a boost in performance, if your car can handle it.
Gasoline grade affects engine performance in many ways. Depending on the octane rating, higher grades of gasoline can help prevent spark knock, which is a knocking or pinging sound that can result from early combustion of the fuel-air mixture.
Higher-octane fuel can also help reduce carbon build up in the combustion chamber and on the valves of the engine. Higher-grade fuel can also help boost engine performance by increasing power and torque, as well as providing better fuel economy.
