Regular, current, on-the-shelf Mobil-1 does just fine for 15k mile drains in a mechanically sound engine. There is not a single UOA posted here, or on the Internet as a whole where Mobil-1 left in the engine for an extended interval has caused either excessive wear or been subject to oil breakdown.
Mobil speaks of things such as '37% more Supersyn' and such. 37% more of an unknown constituent is still an unknown. Also, the website design seems to imply that the base Mobil-1 Supersyn product might be dissappearing (what we buy today), replaced by the Mobil-1 Extended Performance. It will be interesting to see what happens -- maybe there is a solid reason behind the Pep Boys calenders and such.
