I'd take back the Mobil1 and get the Castrol GTX, Pennzoil dino, Havoline or any name brand dino and change it out every 5k or 6months unless you do only short trips (less than 10 miles one way most of the time).
If you do that, then I'd go 5k miles or 4 months.
Take care, Bill
PS: Unless your using oil, NO need for the High Mileage oils like Max life and such..
Stay with normal oils...
