This isn't true. There is not going to be any extra wear from idling for 10 minutes when the car is cold vs driving away after 30 seconds. I'm not saying you SHOULD idle for 10 minutes, but any wear caused by this will be NEGLIGIBLE over the life of your car. Excessive idling like stop and go traffic for 1 hour or more every day, could cause excessive bearing wear though. Even that probably won't make a difference in overall engine service life.

Let me repeat this one more time though, I am NOT suggesting that you warm your car up for 10 minutes before you start driving. I'm just trying to make it clear that if you did, it is not going to mean replacing your engine sooner than the guy who idles for 30 seconds before driving.
