I have 82,000 miles on my B8 S4 and not burning a drop of oil. I'm just finished a 12,000 mile oil change interval and received a great analysis by Blackstone. I followed the Motoman/ Dr GP method for break in. It works.
Oh there are threads all over the place on this one. Everyone had an opinion and opinions are like, mmm something - forget what, but everyone has one.
Break in back in the day for the American Iron I built and drove in my youth (big block Pontiac, Chevy stroker, etc.) was a huge issue. Now, not so much. Modern engines, not built in my garage, are different.
I tend to agree with Motoman. My entirely non-scientific and completely anecdotal experience with a statistically insignificantly small sample of modern engines is that the one I broke in gently burned oil like crazy for the whole time I had it - the others did not.
I did baby the new S4 driving it home yesterday. I don't baby the car past the first 100 miles but I also do not beat the snot out of it. Honestly, even when broken in, I do not beat on any engine cold. Even the one last romp with the M3 yesterday on the way to the dealership did not occur until the oil was at temperature. I needed to hear the V8 howl one last time.
I will break it in my way over the first 500-1000 miles. As an aside, the dealer said nothing to me about break in. Once warm, I will do a few hard near WOT runs stopping short of redline (I understand the S-tronic will take care of that for me if I get too close) and engine brake back down. That should help seat the oil rings, if not already seated. I have a long road trip scheduled for two weeks from now, so I am not sure what I will do there. I may allocate some more time for that trip and drive a portion of it local on surface streets to avoid steady highway driving unless I can put some miles on it next week. I suspect it will still be under 150 miles when I leave for that trip. I may just take the wife's car and leave the S4 for her.
My M3 had a detailed break in regimen, specified with limits/restrictions, listed out on a sticker on the windshield and in the manual. It had details for "proper" use through the first 3000 miles, IIRC. The limits were not that strict, even for the first few miles. Keep it under 100mph. Keep the RPM under 6000k, etc. Mandated oil change at 1500 miles. I do think the M3 break in oil was different than the usual oil, but I am not sure on that one.
Overall, my opinion is: Drive it. Enjoy it. Don't beat the snot out of it for the first 1000 miles. Run up and down in the gears as much as is reasonable. Avoid steady speed, like long highway drives. Leave the break in oil in it until first scheduled change.
but it is only an opinion. And I didn't read the manual that came with the car yet either.
