OK here is my story I am looking for an oil that doesn't seperate from the gas, and can protect in all conditions.
I have been using castor 927 for the last 5 years- separates way to fast sometimes in 2 weeks doesn't seem to bother the quads to much but the dirt bike has serious issues with it.
Super M- used since last summer, found it to be a bit better doesn't separate as easy seems to protect just as good smokes less (i think). But regardless still separates.
Amsoil interceptor- Ran good but crazy expensive no complaints by me but the flash point was a bit low.
Really want to try motul 7100- because I want to run 1 oil in all my machines I have 3 machines do trail and dune riding and I know 7100 is great for trail but not so much for dunes.
Motul 800- great for dune but spoogy in the trials.
what are you guys runing? Im looking for a decent oil that isn't $20 a quart.
