I went to Red line syn in my diesel westy, works great in the trans stopped
the noises. But I regret putting in the crank case.  It started to go
through oil like it was water.  I went to 30 wt. now I have slowed it by
going a mix of 30 wt. 50 wt. & Smoke B-Gone, like an STP.
So if I could do it again I would  I would have suck with the 30 wt.Rotella.
