Pump Gas

LOL.. If your engine lives on the edge with 93 and 91 detonates it, then you need race gas mix though you survive on 93. I'll say it again, pump gas means you can pull into Casey's, Walmart, BP, Phillip 66, Kwik Star, grab whatever the best they have and fill er up and head on out on your merry way.
Completely disagree on the first point. If it's happy on 93, there's no reason for a race mix.
