I'll idle for 5 to 30 minutes, depending on the temps. With the manual high idle you'll help eliminate wet stacking which is the problem with normal idling.

When we hit -7 below F or colder I set my rig to auto run for 36 minutes every 2.5 hours to keep it thawed and make sure it'll start after 10 hours of sitting out in the cold on some isolate pull out with no power to plug into

Experience can be a hard lesson when your rig freezes up and it's -25 below F and your a 100 miles from anything.

 

speaking of experience, I am sure glad you are posting yours for our benefit. It helps to have a cold weather expert chime in on these threads. Because as you can see from the other thread, fellas like me can get into some serious tail-chasing! Again, much appreciated.

 

Your welcome, but I wouldn't say expert, otherwise I wouldn't have gather all this knowledge the hard way and I know there's always more to come....
