Why don't you start a new thread addressing this issue?quote:

I agree...and how does 'varnish occurring' show up on a UOA? I'm guessing it doesn't...and may even account for some of the superlative showings...
A good varnish coating might help to show some good low numbers, because wear metals get sealed in with the coating.
I think you can be building light varnish even with 3K oci's. imho.
You? Biased towards 15w-40 HDEO?quote:

Yikes! I am skeptical of claims like this, but............ya never know I guess. Yea, the oil pump on these afe designated engines is, well, TINY! I mean, the size of the rotors is like micro; they are about the size of a large pinion gear for an RC car enginequote:

had a friend with a similar year corolla that fed his car a steady diet of 15w-40 and it caused the oil pump to fail and seized the engine. Had to get a whole new longblock assembly, saved the heads though. From what he was telling me, the oil pumps in those things are way underbuilt, and if you use too heavy of an oil, it'll fry it out and you're stuck with the bill.
