Is premium gas diesel?

Is premium gas better for your car?
The high octane in premium gas provides greater resistance to engine knock, which happens when the fuel-air mixture in an engine combusts too early. In cars with high compression engines, the elevated knock threshold can allow for more aggressive timing and higher boost pressures to improve engine performance.
Does premium gas clean your engine?
Nope. Regular, plus, and premium gas all come with detergents to mitigate against carbon deposits in your engine. Plus and premium don’t come with special powers for cleaning out the engine. If you’re interested in cleaning out your engine, you’re better off taking it in for service.
