popsracer: Don't get me wrong, I saw your humor in there.
As for your suggestion of trying a quart of another brand...I'll do that. Since I haven't run my Reflex and O.S. .12TR at all yet, I'll try the two different fuels in my buggy and see what I find.
Again though, I have taken apart my OFNA .15 engine many times and have yet to see any discoloration from the fuel. This was with their regular blend, not the Race Blend, though. So perhapes the problems are coming from their Race blend fuel...hmmm
I actually wanted to try the Trinity fuel for racing, but none of the shops around here carry it, and I really didn't want to buy four gallons at once just to mail order it.
