Today's engine's are machined so well that at 1,000 miles the rings were seated about 900 miles ago. There is no "Break in" oil in the engine. That's why they tell you to go 7,500 miles before changing the factory fill.
>>>Not discounting the rental story. No doubt years ago the best way to break in an engine was to "drive it like you stole it/rented it".
I am a fan of Mobil 1. Been using it for several years on high mileage Chevy V8 engines. That's what I would use in a brand new truck.
