What does higher octane gas do?
Higher octane allows engines to have higher compression ratios (for a more energetic explosion), more advanced ignition timing or forced-air induction like turbochargers or superchargers. … It’s the fuel’s ability to be compressed more without pre-igniting that results in more power when used in the appropriate engine.
Can I put 93 in my 91 car?
