Well for my new 347 after break in is finished i was reccomended to use Mobil 1 15w-50 oil. All i can find anywhere is Mobil 1 15w-50 extended performance. Is it the same thing and they just changed the name? anyone got any info?
HISSIN50 said:Agreed. The basestocks have gotten so much better in recent years (as well as metallurgy and machining tolerances in engines) that an extended OCI even on a Gp II oil is possible. And for any Gp III, III+ or PAO basestock, it's easy.
A UOA is a great way to see how long one can run a given oil in an engine, and the knowledge pays for the test (about 20 bucks, IIRC).
