Does gasoline with a higher octane reading actually mean better performance out of your car?

Maybe, maybe not. You should use the lowest octane rating that your can will run on without pinging. Your owners manual is a good place to start. If you use a higher octane rating than your engine needs, all you;re doing is wasting money. As the car ages, carbon builds up in the engine combustion chamber and compression increases and then it becomes necessary to move up one notch in octane rating in the gasoline you buy.

This has been asked for years... but the answer is no. The higher octane fuel is designed for engines with higher combustion ratings, so it won't pre-detonate. Honestly, your best bet is to just go with what your owners manual recommends. You're most likely just spending more on fuel when you may not have to.

YES. It allows the engine to fire the sparkplugs earlier for more complete combustion, and longer burn time.
