greased lightning
Just wanted to weigh in on this. For a long time i was under the impression that 14* on a stock engine was simply to much advance to run 87. Then here recently, guys start comin out of the woodwork sayin they run 87 without mishap. So im happy to say i tried it and the truck runs pretty much the best it ever has, which is comforting considering it has 180,xxx miles and that would seem to indicate that at least carbon buildup isnt a problem yet. No detonation that i can hear at WOT. So yeah, i got that goin for me, which is nice
