I can't really speculate on the demand for that racing fuel. I think it's a legitimate concern, but given the options in the area we don't have much of a choice.

I do want to say based on my own experience that octane ratings 91 vs 93 vs 95 vs 100 have a larger material effect than comparing Shell vs Chevron vs 76, all at 91.
