I already cooked one barring and had it replaced under warranty (the whole motor) and I don't want to do that again.
If you daily drive pretty hard, i wouldn't run Mobil 1 Extend Life for the full 15,000 miles. I'd think 10,000 would be pretty acceptable though. Changing oil more frequently can do nothing but good for your engine.
