Just for conversation, here is the rule, in part, for gasoline, in the sports car club of america (SCCA) autocross rulebook. FYI "STREET" is more like "Pure Stock" and "Street Touring" is a little like "Stock." The rule used to be "must be pump gas..." would it help or hinder NHRA Stock class if a similar rule was adopted?

"3.6 FUEL A. Street and Street Touring® category vehicles will use fuel which is “Federally approved for use on public highways,” and which does not exceed an octane rating of 93 AKI (Anti-Knock Index = [R+M]/2) with an al lowed variance up to +0.9. Fuel may not exceed 15% ethanol (E15). "
