What’s the point of literally anything but regular gas?
@amarand @Dane Higher performance engines utilize higher compression ratios. Regular grade gas can prematurely detonate due to this higher pressure and that's problematic. Premium gas is engineered to work in these higher compression engines without that problem. The EC in my wife's 2022 CX-5 Turbo can sense what grade fuel it's using and will adjust the engine's horsepower output automatically.
“Higher performance engines” sounds like a rich person problem to me, though.
@Dane @amarand @MakerWerks Had a 72 Challenger and dropped a 440 in it, hooker headers, alum. intake, changed from points to electronic, and put B2 heads, 3in exhaust w turndowns WAY before rear axle lol. Had to sell it when I moved, saddest day ever.
