That's why I'll just pay the extra $5 per 5QT bottle at WM to get the Extended Performance version.
That said, until recently I ran 'regular' M1 in my cars and would still swear by it. I still run regular M1 in my wife's Pilot, but run EP in her EoS R32 and my IS350.
I'd like to try the new 0W30 Mobil and see if that really gives any improvment in MPG, however.
