Octane requirements

Not everyone can simply ignore reality and drive a car that gets 7mpg on premium.

I run 110 in my Roadrunner, at $9 a gallon. Sometimes I mix in a little 90 Rec fuel if I think I can’t make it up to the next town where they have 110. I’m not rich, but I don’t drink or smoke, so if I splurge it’s going to be on the car. And, my Mom loves the smell of 110, so I burn it for her!
