i think it is a good discussion so far and many valid points. i just can't agree that all oils perform the same. on a side note my old 1969 skidoo olympic by spec is suppose to be run at 24:1, lol thats alot of oil! i just run the 50:1 in everything and everything runs fine. todays oils are leaps and bounds better than back then. when i did stray away from synth oil i first went to the quicksilver for 8-12L and then tried the redline semi, and then some shell nautilous believing that all "dino" oils are the same. the thing i like about the synth is the additive packages they use. some of the really good race oil is specifically designed to be blended with race fuel. but hey, all oils are the same, haha. Its true whats been said everyone just loves their brand of oil, just like in eveything else in life, chevy ford yamaha kawi skidoo polaris 2 stroke 4 stroke. It must be winter.
