1000 km according to the manual of steady drving.
most ppl on here nail it from the word go coz it creates a better piston seal.
personally i varied the revs for the first few hundred miles as in a few short acceleration bursts.
Basically dont hammer from cold, dont keep at a constant speed for a long time, ie dont use your cruise control, and dont labour the engine, ie dont climb hills in high gears where the engine is struggling to move the car.
