Can I get some feed back on my results. It is an cm 870, with egr valve still on and working , 500hp, 13 spd, 3.73 rears. Mileage 865000.

16k miles with 11 on the iron is decent. That rotella has 1100 zinc and that is good too.

However though... if you have 800k miles on it then it is well due for new rod and main bearings. -- You need to do this now and not wait any longer. - Doing this will ensure the bottom end (wrist pins especially) holds up well into the 1.3+ million mile range, and not doing it now ( recommended at 800k) will become a curse later on that will haunt you ias the engine makes it past a million.
