I forget which Syn Castrol is supposed to be far superiour to any of the Rotella, but I put it in the bike. That was 2 weeks ago, and I've had fair results w/ it,...fair only because I didn't see a 20% increase in gas milage that they said. Maybe I'll drain it, and get my money back.
But like they said, the clutch ain't slippin w/ this expensive oil !
But then, I don't remember it slippin before I changed the oil either. I think I'm confused,........these oil threads always confuse me.
