That’s a non issue, I live in PA where -20 spells with wind chill aren’t uncommon and I don’t plug in my older 5.9s, my 7.3 powerstroke which are notoriously ****** cold starters, and certainly not my 6.7 cummins. The 3.0 DURAMAX (not babymax) like any other modern diesel doesn’t have issues in cold weather.
You may be right..but we routinely get 2-3 weeks a winter where the HIGH temp for the day is 0, with some days where the high is -10, and the lows are -25 ish...
I didn't see a cycle of:
Sit in garage at 10F
Cold Start
Drive 7 miles to work
Sit in parking lot, soaking at 0 (or -10) all day
Go outside at 5:30pm where actual temp is -10
Cold Start
Drive 7 miles home
Repeat 5x days in a row being a good situation w/ the Diesel and DPF and DEF....seemed like a recipe for failed exhaust regen cycles...
If I were taking longer trips to/from work, I would have considered it...maybe I am a fool...
