Mobil 1 EP 5w/30,10K oci,05 Colorado

[NewC-05]

here's my latest results with M1EP 5w-30 from Aug.07-March 08 using 93 octane.drained and added 1qt of 15w-50 at the 5k oil filter change. results were not much different compared to the last 10oci using just 5w-30, at least not enough to warrent using 15-50 at the half way mark (unless someone sees something possitive i don't?). looks like i'll keep it simple and stick with 5w-30 through out...

Looks good but the Tbn is low for only 10k miles IMO.
