"Running In" question
I was reading through both the 1 Series Owner’s Manual and the 1M Supplement Owners Manuel last night and I just want to clarify something.
According to the standard 1 Series Owner’s Manual, under the “Running in” section, it states the following:
Engine and differential
Drive at varying road speeds, but do not exceed an engine speed of 4500 rpm or a road speed of 100mph/160km/h.
However, in the 1M Supplement Manual, it states the following:
Running in
Contrary to the description provided in the Owner’s Handbook for Vehicle, the following deviations should be taken into consideration for your BMW 1 Series M Coupe:
Up to 2000km, approx.. 1200 miles
Drive at varying road and engine speeds, but do not exceed 5500 rpm and 170km/h, approx. 110mph.
Avoid pressing the accelerator pedal all the way down to full throttle position.
So, is everyone running their cars in using up to 5500rpm or 4500rpm? From what I read on here, it appears to be the latter?
