Idling the Engine
When I had my 7.3 I was cautioned not to idle it at low rpm. When it was cold I used the auxilliary engine controller that was on the truck and ran it up to 1100 to 1200 rpm to warm up on a cold day. (I could start it at 25 below without a plug in, sound like 30 guys breaking rocks with hammers till it got the chill out.) I tried to never let it sit at low idle. Driving it I tried to keep it turning about 1700 plus for highway. After 310,000 Kms the engine still ran like the day it was born.
I see lots of folks doing long idles at low rpm and I'm thinking that is just coking up these modern diesels.
Correct me if I'm wrong but it seems that the low speed idling and lugging around town at low rpm is probably the kiss of death for the 6 litre?
Ran mine today on a logging road in heavy snow to exercise the 4x4 and it seemed to really like running in the 2000 to 2500 rpm range and even more for giving it a good work out.

Thats why we have the high idle mod, runs at 1250 rpm approx. Also, the 6.0 has a temp strategy which idles it up to about 1000 rpm when its cold outside and the oil temp is still cold. The worst thing you can do is idle when its really cold, it does coke up because the air pumping in is still cold and its not generating enough heat to keep warm. Best solution is to let it warm a bit and then drive it. You do need a winter front if its cold otherwise its going to be cold even running highway with no load.

mhoefer, that is exactly my strategy. I start it wait 15 to 30 secs to get the oil flowing and then drive. I try to keep under 2000 rpm till the temp gauge starts to move and don't fire wall the throttle until it is warmed.
