I use the M1 EP line and it holds up well for many more miles than you went. I do 10,000 mile OCIs and the two UOAs I did came back with plenty of life left.Is the 5 qts of top off oil correct? Can't be.
The OP shows 5 quarts of makeup oil. That's high but not totally unexpected with this engine, assuming it was driven aggressively. I have an '03 S2000 and although I don't consume nearly as much oil as the OP does, I still get criticized for my oil consumption.
This is a good UOA, and testament to a great engine. The oil sheared down, which is typical of Mobil 1.
Thanks for posting.
This engine shears oil....freaking 8000rpm+ redline! Many posters here are terrified of anything over 3k lol, so your UOA'sare bound to reflect this.
Once again, for the particular car...this UOA is pretty good. I think he should switch to M1 10w-30 high mileage....now thats a stout oil!
I agree with Indymac: The F22C engine usually doesn't burn oil, however if it's aggressively driven, he may be losing a lot of oil through the PCV valve. Switching oils on this engine has worked for some S2000 owners, so it's worth a try. Otherwise, the OP may want to consider Krank Vents (note: this suggestion is specific to the S2000 engine).
I've seen numerous UOAs on this engine, and I can't recall ever seeing one using Mobil 1 that didn't shear a fair amount.
