There's more to UOA than wear metals. If your engine is seeming to like the heavier viscosity that you swapped to, I want to see if there's a reason for that. I see some engines that follow this same trait, especially 3 chain engines, as the vane cell adjusters on the intake cams have proven to at times have internal oil volume losses, which increases the engine's desire for a heavier grade oil.

Thanks, Jake for all that you do on this Forum and Rennlist. E-mail sent.
