All of the gasolines he sells are legal in the gasoline class, including 110K. 110K is more or less the "standard" racing gas that works well in 80% of the race motors. He has others, though, more suitable for say nitrous and/or forced induction, that have higher octane, but in some cases lower heat content. I believe he also has unleaded race gas. Any of them can be run in a gas class.
