dude? not one person thats ever posted here is a expert. me either. just being real. If you want to use the redline- go for it. its my oil of choice. If you are new to these little engines-- run 24 to 1. as you learn the effects of temp changes- moistures effects on these engines- have it down to a art-- hell, go ahead and lean out the gas oil mix. less oil equils more gas-- so, it will make the engine run richer. just be careful. In real life conditions on these cars, MOST users are in confined areas, not really wide open throttle for long anyways-- about 30 seconds where i live-- distance of a football field. d.b.
