Sorry I dont know where to put this on the site.
I was reading on here somewhere about you guys buying race fuel at the track I think 109 octane, and talking about octane additives and such. My question is this.... Is it unleaded fuel? If it's not how do you guys with cats deal with that? I live in a very small, remote town but we do have a fuel distributer. I just checked with them and they have 113 octane but leaded for 5.60/gal. Pretty good I thought since avgas right now (100LL) is over 6 bucks a gallon.
