Hi Everyone,


About 27 degrees this morning. Ran 350 miles in the snow yessterday. Got a little puff of blue smoke at startup this morning.


Is this normal? 3200 miles on truck.

Wait 'till it gets down to around 0 degrees....whoa!! When I fired my truck up at 2 below leaving work Monday afternoon, I looked like I was fogging for bugs for a little bit!! Probably lasted for 20-30 seconds or so.

Both mine and my dad's do it also, as well as my 6.5 van. As smooth as the duramax is, it's still a diesel, and all diesels do seemingly-alarming things when they're cold-started in a cold climate.


I do say, we've been spoiled by how electric-feeling these engines are compared to the diesels of yesterday. Drive it and enjoy.

Mine does the same thing.


I'm not going to worry about it, oil level has not moved so i don't think it oil related.

Thanks everyone. First diesel. Anything blue out of a gas engine exhaust always alarmed me in the past. 175 miles on packed snow from Seattle to Portland Tuesday morning in mostly 2 WD, and 175 miles back in 4-6" snow, washboard and ice in 4 WD. LOVE this truck.
