Thanks for the links. Not having any issues, jus want to change things up, it's also much cheaper. I heard some real good things about it actually. I'm familiar with big equipment n also know that tractor oil is bout the best oil out there. It's designed to be run for very long periods of time on expensive equipment. From what I hear the guys running it say its clean and when it's time to change out still looks new and can take some real abuse. I picked some up, gonna give it a shot. The only worry I have is getting some that's compatible with a wet clutch but I think this stuff is, I'll report the results...
