Personally I have run Amsoil Interceptor in both my Proclimbs, my 13' had it in since day 1. I ran it to 1300miles and pulled the pipe and y pipe for a buyer of sled and Pistons looked immaculate and compression was right on the money, both jugs within 1 psi of each other.
Talked to him the other day and he now has over 3200 miles on sled and used Interceptor since he bought it from me, not one issue.
I use Dominator in my race KTM 300 since day 1, running 50/50 100LL av has, ran it HARD for 100 hours including 25 of those hours in Oregon sand dunes. Pulled the jug to replace piston and piston is within 0.001" of brand new spec!!! I said screw it and and just put a set of rings in it. Bike has SX base gasket, SXS head, SX ignition. Hauls royal *** and resides in the gnarliest riding BC has to offer.
