I know there are probably post about this on here already I just dont feel like looking. Ok so I have heard that these high performance oils like klots, and amsoil performance ect. gunk up powervalves. I was told that honda oils and suzuki oil is the way to go because it doesnt. What are you opinions/ experiences with this? I was told this by my local mechanic/ good friend. Any input would be appreciated.

Thank you,
Tripp
