For sure, the maintenance level does help, but there is more.

You all know that a race engine that spins continuously at 9-10k rpm has a short life span, maybe a few hours. On the other side of the spectrum, you find big tractor-trailers that rev at 2k rpm and will last for millons of miles.

My point is that the higher at which the motor is revved, the shorter its lifespan. Exponently.

So, an M3 engine that has been driven on the highway all its life and has been spun at 5k rpm will last 200k miles. Do not even hope to get the same results with an engine that has been raced...
