I received an email from a local Ram dealer containing an article called, "Warming Up Could be Killing Your Engine" and thought some of you might be interested in it. It cautions against warming up your engine. The ONLY time I intentionally warm up my engine for 2 or 3 minutes is in the dead of a WI winter. And years ago I was told that it is better for the vehicle to be driven slowly out of the subdivision for a couple of minutes as opposed to idling in the driveway. Glad I've been doing something right!
