What does everyone think of the redline synthetic 2-stroke oil? Im just using that to practice with the 110octane IMI sold me. I think because 110 burns much slower, the kart actually runs cooler than it usually would ( I only saw 110degrees on temp). In all honestly, from what I know about fuel, you use different octanes, etc because of compression ratio and timing. Since the MOTOR is spec, and neither of those variable can be changed, it really shouldnt matter what kind of fuel you use. I doubt you’ll see any performance advantage at all. Just my 2 cents.
