At Petro Express stations around here, I have noticed them selling 100 octane gas. It is like $5 a gallon or something crazy like that. It isn't E85 or anything as far as I know. What is the use for this stuff? The nearest drag strip is at least 25 miles away or so in Mooresville, NC, but every Petro Express around here has the stuff. Is it just a gimmick for the "Fast and the Furious" types? If it wasn't so expensive I'd put some in the Exploder just to see how it would respond to it.
