There's been several threads explaining in considerable technical detail why it's bad for an engine to idle it to warm it up (or in general).
The owners manual explicitly states you shouldn't "warm up" the car before driving it and excessive Idling is in fact one of the things that kicks a car into the 'severe duty' maintenance schedule in the service manual and
Proper "warm up" is done by driving the vehicle.
All sitting there letting it warm does is waste fuel and contaminate your oil with condensation and blow-by from piston rings that seal poorly at idle.
Here's one of the super-long threads on the topic-

There's some 1950s-era "You should warm your car up!" BS early on page 2, but later in the page, and through the rest of the thread, you get folks who actually know WTF they're talking (Gernby, Lobuxracer, and others) about explaining why this advice hasn't been true for many many years on modern cars, and why it's actually bad to do it.

^^^^^Totally agree
This is really good to know, I usually let my 250 sit for about thirty seconds before putting it in drive so that probably doesn't count as warming it up. I never warm up my Tahoe as I feel like the engine is so big it's warm after igniton
. However... My 08 Subaru Impreza had a cold engine light, and the owners manual recommended that you waited until this light turned off before driving the car. Obviously there is the engine difference (Boxxer 4 vs. Inline 6), so would the smaller engine size make it worth it to warm the car up, or be just as bad? Don't have the Subaru anymore but just curious.
