Does anyone have any opinions as to whether Mobil 1 EXTENDED PERFORMANCE really offers anything beyond regular Mobil 1? For what it's worth, here's Mobil's official answer:

What is the difference between Mobil 1® Extended Performance and Mobil 1?

Mobil 1 Extended Performance formulas are designed specifically for today's longer service intervals and are guaranteed to protect for up to 15,000 miles or one year.

Mobil 1 Extended Performance has a unique formulation with a boosted level of protection and performance. Mobil 1 Extended Performance, with the Advanced SuperSyn System, contains 50 percent more SuperSyn than Mobil 1. (Updated March 2006)


No desire to start another big hairy oil thread....but hadn't seen this particular question addressed when I searched.

Thanks.
