A good example is my 09 WR250F. Ran probably 150 Hours, 45-50 races. Heat, mud, you name it. Never adjusted the valves, never replaced the top end, stock clutch plates. Changed my oil efter every ride and it makes all the difference. Is the same with every other bike I ever owned, even when it wasn't a Yamaha. Best oil, hands down.Read All Reviews

I swear i could hear more valvetrain racket than with my normal oil so i switched after one ride back to my previous oil. Could have just been me being paranoid but wasnt worth it to me. 3 stars because unsure if it was my imagination or really was the oil.Read All Reviews
