Cold weather and diesels

Sounds pretty good Bill. If I keep mine on the interstate with no load, and keep my foot out of it, I get over 22. I have about 9k on my duramax. Thats way way too high, so ill fix that by getting an Airstream soon.

You might want to check the DIC by hand calculating . Some are high and some are low , mine is 2mpg more than actual .

I've checked mine on numerous occasions and it's been dead on! Acturally sort of scary. Lately, I've been able to routinely get 20 mpg for several hundred miles running on the flat - but I've never-ever seen 22! I'm probably a lot heavier than others - at 8,400 lbs without the trailer. That best mpg figure is also based on running about 60 mph. Overall, and with a lot of hills and mountains, I probably average about 17.5 mpg solo. The mpg average overall (---over 50,000 miles) is right at 14 mpg on the DIC - which probably includes about 35% towing.

I didn't realize this was so far off the topic of cold-weather and diesels! Sorry 'bout that.

You're one of the lucky ones , I wish there was some way to calibrate the DIC . My actual MPG is similar to yours . One time I did get 22 MPG on a 600 mile trip to Maryland . 20.5 on the way back , it must be an elevation thing.
