[TrufflePig]

what you guys reckon is the break in period for:

Mini Cooper

Mini Cooper S

Mini Cooper S with JCW

cheers

[KPKalle]

Read the manual. Something like 4000kms or 2500 miles

[MirandaCooperS2006]

I'm going to have to wait 4000km till I can really drive my future Mini Cooper S?! Road trip anyone???

I thought the break-in period was usually only 1000km ... but I am a newbie!

I am not near my manual, but I'm pretty sure it says 500 miles, which is around 1000 kms.

It says something about not redlining it in that period.

[TrufflePig]

MsMiranda why 4000kms.

cheers

I thought it was 1250miles for the Cooper S?

# Official engine break-in is under varying engine and vehicle speed and do not exceed 4500RPM/90MPH
# Break-in means longer life. db followed break-in to the letter, and now has over 112K miles with great gas mileage!
# We are going with the engineers on break-in
# Tire break-in = about 200 miles/300KM
# Breaks break-in = about 300 miles/500KM
# Clutch break-in = about 300 miles/500KM
# db & Gabe share S-10 stories

that it's 1250miles and not to exceed 95mph.

1250miles engine break in, never "full throttle it" (manual says this specifically if i recall), keep the revs below either 4k or 4.5k
tyres, clutches, brakes etc are all in the 200-400 mile mark.

basically just be a sunday driver for at least 1000 miles

It will be ok. As they said in the movie The Black Pearl, "Thems more like guidelines"... An occasional excursion will not be a disaster.

The day after I pick up the GP, I am going to drive it all day every day on a coast to coast trip. Drive it like you bought it, not like you stole it and you will be fine.

Hehe...once you put ur foot on the paddle, man..trust me..with the whine sound surrounding your cockpit...it'll blow ur mind!!!...Plus you've got no back seat for the GP...it'd makes the sound echoing in the back of ur ears...you'd wish u had stolen it..mmmm...and everything is fine....

What the break-in period does is allow the moving parts in the engine to "mate" properly with each other. There are always "high spots" like miniscule hills of metal on any metal surface. These will create more heat when subject to friction such as against another moving part, e.g. piston against cyclinder bore, or bearing agains crankshaft etc. The break-in period is to allow these "high spots" to be rubbed down withouyt creating too much extra heat which could otherwise seize those metal pieces together. Obviously the longer you allow the break in to operate the better these surfaces will mate.
