How r u doing? One question. Why do people insist on running some new fuel that promises the world, and it always seems to use less oil. Around 8-9 percent usually, then guys burn up engines, not that the fuel is so terrble it's just they aren't experts at tuning and so on, so why do they have to buy into these gimmicks. I insist that fuel needs plenty of oil to work good, burnishing on break in, longevity, and so on. I like 11-14 percent, and currently I'm using Byrons 25% with 11% oil and it moves it out at the track. I did use Power Master 25% and it has 12% oil. Usually the higher oil content fuels have aound 50/50 mix synthetic/ castor, but the lower oil fuels use too much synthetic, and we all know castor oil is important....Wht is your opinion on the subject??????
