Fuel perfume, damn that's for us 100 octane and leaded fuel guys when we go on dates I guess. You smell nice, thanks it's Racin Raspberry. WTH
E85 is a better smell than 100 octane or higher that's for sure. I do back to back start ups over the winter between my 2 cars and my GTO on 100 octane will kill the closest room to my garage while GN on E77 (now like E40) doesn't do much at all.
