Unnessacary idling is one of the things you should NOT do to your engine. Lower combustion pressure and boost levels result in increased carbon deposit build up in rings and raised soot levels in your oil.

JUst pull off the interstate and gonna run in and grab a soda and letting it run is one thing. Sitting down at McDs to get your burger on though is another and I don't reccomend it.

I do not like to let mine idle for long periods of time. I wouldn't mind if I had the high idle switch, but just at a regular idle, I wouldn't let it idle for any longer than a warm up.

I let mine idle when im sleeping in it and its cold outside, or hot outside. This is a rare occasion, only when i have an overnight haul. Never noticed any harm done to the truck.

never idle for long periods

From area GM rep and my top Diesel tech. The way the turbo is set up this truck, it likes to be spooled pretty good, but running idle you lose oil flow or pressure. It will cause a premature leakage from the oil feeder tube to the turbo, not a lot of oil at first......then ya will see it running down everwhere. I would only idle at stops lights (duh) and when fueling or making a quick drop off. But after I found this info out and sprung the leak. I cut it off more often.
