Every vehicle I ever bought new I followed that belief. I found that every vehicle got the best mileage the way it was broke in & performed the best that way also.
The old saying use to be that if it is going to blow let it do it on Fords dime, not mine.
I agree with giving it a few hundred miles but after that all bets are off. Every engine or tranny I ever rebuilt got that same treatment. The only difference was I would vary my speeds & pull on the rebuilt engines for a good 500 miles to seat the rings. But that never meant babying it.
