Don't warmup up your car-R&T
R&T At least not your gasser, don't know if it applies to diesels.

I drove a marked police car for 13 years of my career. For the majority of those years, the cars ran the entire 10 hours of my shift, 4 shifts per week, 52 weeks per year. My last car was a 2007 Crown Vic that had 140K miles on it. That thing idled all day, was driven HARD and never had any engine issues.
The electronic demands of that vehicle overwhelmed the batteries, requiring them to be on all the time or risk it not starting when we needed it.
I'm not sure I believe these horror stories about engine failures. Now... do the engines NEED this? Probably not. In my diesel I tend to start the truck, then help the kiddos buckle their car seats, then get in and drive. If its cold, I'll start the truck a minute or two before we head out the door. With the exhaust brake and high idle feature, I can get heat within a couple of minutes.
