: engine "break in" period

04-01-2004, 05:22 PM
Anybody have any experience with this? I'm taking delivery of a 2004 X5 3.0 and I have to drive to another city 180 miles away for some previous plans.

Should I be worried?

Don't use cruise control.

Vary engine speeds while on the highway.

No big concern.

Your engine was probably as broken in as its going to get when they ran it at the factory.

But you should not use the cruise control or spend excessive time at high RPM. Short bursts once the engine is warmed up are OK.
