Jiggy.. all jokes aside bro..
the v8 is like the 3.2 is like the 3.0. proper maintenance is required and proper driving is required. its not a vtec or mark 1 that you can start up and rev to limiter. in all honesty, no car should be treated this way.
I learnt over the years that you one needs to spend money on good grade oil and proper oil filter because this is the heart of your car. Like with the human body, healthy blood, healthy body. Good oil, good engine..
in the M3 manual, they tell you and I quote from my manual, the correct operating temperature lies between 80 degrees C and 120degrees C. if the car is driven in an enthusiastic manner, a temperature of 130 degree C should not be exceeded. Until engine oil temperature reaches 50 degrees C, do not exceed an engine speed of 4000rpms
my car has 260 000 on the clock, serviced regularly and driven fairly well from what I understand and she doesn't smoke or have any funny rattles. My dad traded in a 525I MEX years ago with 428 000 km on it.. never been opened but that is proper maintenance and proper driving. don't get me wrong, my dad is quite an enthusiastic driver, the man raced at goodwood show grounds back in the day and used to be part of the hell drivers but its just how you prepare before actually giving the car stick..
my 2 cents
