From the date of this post I'm guessing it's too late now but here is the method taught to me by my grandfather, an old-fashioned A grade mechanic.

1. For the fist 300 miles: accelerate quickly up to open road speed then gradually slow down to 30 Ml/Hr. And repeat. Change the oil after the 300miles.

2. Don't 'baby' the engine - drive at normal speeds, normal acceleration. If you baby the engine it will produce ridges at the top/bottom of the cylinder which can break the rings when you have to work the engine hard.

3. Best to have a sign in the back window to let the frustrated people behind you know.



The more modern method is to just drive the car in a normal manner.

Hope this helps
