There is a belief among a lot of people that you should start your car and leave it on for 5 minutes before moving it in the morning. Is this practice good for the car in any significant way, or it is just a myth?
Once upon a time on old car engines this was required, and piston engined aircraft warm up because they stress their engines to the maximum as the first thing they do. But this is no longer necessary for modern cars. The recommended warmup time vary between 15 seconds and three minutes.
