I have switched over from Cool Power 30% to Wildcat 30% Helimix. After 4 gals I have found a improved mid-range and powerful top end over CP. I have found this to be the case with my OS32 , OS61 WC and my OS 50. I'm on my 2nd case and have really been pleased with how consitant my engines run as well as smoother. FWIW
Going on my second case as well unreal is all I have to say. Great Fuel Cheaper than CP less smoke smells great, more power. Less heat no goop in engine. Idles like a dream, runs smooth as glass., :D
