Easy and in two words: Dimensional stability. Alloy engine cases move around quite a bit while warming up. It is not at all unusual for an M96 to have its cylinder bore dimensions move more than a couple of thousandths from stone cold to fully warm. Other parts of the cases move even further. And if the engine is "loaded" (read moving the car) during this period, you are subjecting it to unnecessary wear due to the alloy shifting. So you can protect the environment, or your engine; choice is yours............
