The only place that sells E-85 where I live in a metropolitan area of over 1-million drivers, is one Kroger Food store. There are some turbocharged ricers that use Kroger Food Store's E85. None of the race shops sells the stuff. If you think your fuel system is prepared correctly and can successfully use alcohol based fuel, use VP M1 or M3 Methanol racing fuel that contain lubrication and combustion additives. M3 is easier on the eyes and nose.
Speed shops in my area sell VP M1, M3 and M5 Methanol racing fuels. VP M5 is what the top alcohol race cars use. My cousin, Mark Talliaferro, uses VP M5 Methanol exclusively in his MARKCO Top Alcohol Dragster.
