The higher octane of premium gas won't make your car faster; in fact, the opposite is possible because higher-octane fuel technically has less energy than lower-octane fuel. It's the fuel's ability to be compressed more without pre-igniting that results in more power when used in the appropriate engine.

Is premium and super gas the same?

But what's the difference, other than the price? Regular gas has the lowest octane rating, Premium has a higher octane and Super (or Supreme or Premium Plus) has the highest octane. Octane is the measure of the fuel's ability to resist “knock”.
