1200 mile service break in

So I've heard this go both ways, drive it like you're going to church on Sunday or drive it like you just stole it off the lot an hour ago.

Does it make any real difference how we break these cars in?

Personally, I don't think so. But if you're out racing M5's during your break in period and your differential grenades, don't come crying to us. And they won't be in a hurry to stroke your ego while it's broken because they will know what you've done to it during the break in period. Not that anyone here has done that.

I know a guy who tracks his cars during break in. Here's my take: a car can fail in all kinds of fun ways, especially a performance car, without you ever doing *anything*. So why give the dealer an excuse to make your life harder?

There is no universal consensus. There are three major opinions:

1. Those who ignore the break-in recs completely. In turn, people in this category can be divided into two camps: those who actually believe this type of break-in (e.g. high-revs/max speed ASAP) is either neutral or even beneficial to the long-term life of the engine, diff, etc.; and those who are planning a short-term ownership and really do not care about long-term ramifications of such a break-in.

2. Those who follow break-in directions provided by BMW. Thought process is that the engineers who designed the car know what is best for long-term longevity. The two camps here are those who are planning long-term ownership and those who are not but nonetheless wish to pass on an "unmolested" car to the next owner.

3. Those who don't care either way and just drive the car as the situation demands from the start.

Personally, I am in the #2 camp (usually, but not always with long-term ownership in mind). You could probably spend an entire day on this forum alone reading other opinions...

Agreed, they know what they are talking about. As a holder of my cars, 7 to 10 yrs on average, common sense suggests to follow suggested OEM advise, plus intermediate oil changes never hurt.

I agree 100% on the above.
Do any of you really think you know better than the people that designed and built these fine auto's?
The procedure is there for us to follow, if you ignore it you deserve what you get.
