VP 105 octane leaded (C111 I think). I'm flying in from out of town for the November event, and don't have much time in the schedule to find race gas enroute. I have to pass through Ontario to get to ElMo, as that is where I stash my race trailer. If I could get it enroute, great, but heading down to Signal Hill (last place I bought gas) is not in the cards.
