I fill up at Costco and always get top tier. It's typically around 91 or 92. Old dudes at the corvette shows I go to swear that Costco gas is the best.

Not sure where you've been hearing that. I've used Chevron's 94 for over a year now with no problems. Loving the better efficiency now that I'm not burning ethanol - somehow I went from 11L/100km to 9.5 despite driving harder than before.

87 because I'm a poorfag and I don't really care.

98 exclusively.

There's always one spack

Also, 95 is not standard in europe.
91 with 10% ethanol is. And it's shit.

BP98 at all times

Standard in Germoney is 95 with 5% ethanol.

Ethanol has a lower amount of energy per mass unit than pure gasoline. So less ethanol will mean more mpg provided everything else is kept constant. That's why e85 requires bigger injectors usually.
