Yes, camp fuel and Amsoil has performed best of all, and far too much time has been spent in the past w/ these trials. Even after many seasons, my engines look shiney and new inside w/ no carbon build-up. The camp fuel is time tested too. I got the ideal quite some time ago from an older plane flyer that has used camp gas since the early 80's.
BTW: I mix @ 2oz/gal using the 100:1 premix and Ozark Mountain fuel available in Walmart.
