And start engine/re-builder shopping. 1 quart/1K is INSANE.
OP - Not sure where you are in NY, but you might want to check out EFI Logics in CT or Performance Auto Solutions on Long Island. You can't get much better than either of those in NY, Northern NJ, or LI.
I would probably go with M1 10W40 High Mileage since it's a little thicker than RT6. Either is better than what you're running though.
Yep, there's also The Shop in Norwalk, CT and Prime Motoring in NJ, both of which I've heard good things about. Not sure if Prime does rebuilds though. I'll keep EFI in mind as well. Thanks for the suggestions
Are these wear numbers really that bad that it's a definite rebuild coming soon? Even if switching oils lowers the wear to reasonable levels now?
Also, can anyone provide me with threads/articles that cover
why these higher viscosity oils are recommended? I thought that startup wear was always a factor in picking oil, and a 5W-40 has a higher cold viscosity than a 5W-30 and therefore will cause more wear on startup. Seems like, whether true or not, that's not really relevant to turbo engines, since everyone's suggesting Rotella T6/M1 10W40, which I'm happy to try, but I'd love some more "scientific" reading as to why. Searching didn't turn up much - mostly just "switch to rotella T6 BEACAUSE" type threads lol
Thanks for the help!
