Radiator cover... Use is or not?
I got my truck last week and drove 2 hours to the north side of Denver in 50 degree temps and the temp gage was steady at 210, well just below 210.
I drove it a couple of days ago in 30 degree temps and the engine temp never reached 210. I have a GM radiator cover and I'm wondering if anyone uses radiator covers. I don't see many of them used around here. Will a lower temp decrease the MPG?
I am just trying to get used to running a oil burner.
I am a new LLY owner and I am really happy with the switch from a 90 5.7 Suburban to the 05 duramax. I am learning a lot form this site and appreciate all the knowledge sharing.

I've had my truck in Denver for a couple years now and haven't ever seen the need for a cover for what its worth the trucks always run great regardless of the outside temps. FYI you will want to something about your mouthpiece if you ever plan on hauling anything up over Eisenhower or Vail in the summer.

Yes lower engine temps will greatly affect mileage (Decrease) your fuel isn't burning completely, keeping the engine at operating tempature will net you the best mileage. When engine is cold mileage will decrease a fair amount, I have seen mine go down by 2-4mpg.
I start using my cover once outside temp stay's below 40 degree's. Warm ups are much faster, and mileage will go up.

First, Def. do something with the MP- second, in the 50's the winter cover is not needed, personally in the 30's it is borderline, but any less than that and yes while the truck may run fine, it helps the truck stay warmer (as well as putting heat into the cab)- just DON'T use while towing (unless real cold!!!)
