Sorry guys, it was on my list for changes, and I must have missed it. I beleive it is part of the old NMMA insert. It has been there for a while, is not enforced (not that I condone ignoring any rule), and would be extremely difficult to enforce without significant burden to teams and officials. Paul's a reasonable guy, perhaps we could get a clarification from the track that "track fuel" for 250's is any comercially available pure methanol, and a NMSA approved oil. The rule does not say 'track distributed' or 'track sold'. Just a thought.
