To be fair there is good evidence to suggest that ensuring that the piston rings are well sealed bodes well for a long lasting engine with minimal oil consumption. This is generally achieved by running in the engine hard.
A few years ago (2008) I bought a Panda 100hp new. By 50 miles I'd had it up to 5000rpm, I varied the load and used revs, rather than cruising. By the time I'd done 400 miles I was redlining it.
There was another member on the forum who got his car about the same time as me. He decided to take it very easy never going over 3000rpm for the first 1000 miles and then gradually increasing the rpm. I think he was still running it in at 3000miles.
His car drank oil, mine didn't. Interestingly I generally had lower oil usage than my peers who had been 'gentle' with the run in.
Now, don't think I just redlined my car off the forecourt, because it was nothing like that, but I used revs, some full throttle and importantly lifted off and let the car slow at higher engine speeds. But, by 500 miles I had it run in.
I guess you take your choices. The advice I had from my dealer was just to drive it 'normally'!
