Driving a 335i short distances harmful?
I have about a 4 mile commute to work. I sometimes ride my bike but in winter I drive my 335. I live in a moderate climate so the car is not that cold in the morning. My question is will this do any long term damage to the engine. I usually run some errands on the way home and drive longer to warm it up and it gets a good long drive on most weekends. Any precautions to take in the morning like not revving it high? Thanks for the info.
