Cold weather and diesel advice
So just picked up a new 2019 3500 SRW diesel on Friday. I grew up around cars, my dad is a GM mechanic, but know nothing about diesels. Does anyone have any advice as far as fuel treatments for sum...

Run full synthetic oil and don't worry about the diesel or any additives - if you live in a cold climate the stations will sell winter blend diesel in the winter months.
I agree with this aboout 99%. The one caveat, is fuel "should" be treated to the expected low temps for the geographical area and season, however that is not 100% the case if you're dipping into record low temps.
I only say this because I witnessed the entire Denver metro area caught with their pants down figuratively when there was a -25 to -30 deg cold snap and the local fuel was not treated to that low of temperature. I drove 4 hrs round trip to buy cases of 911 to get our equipment running, while zig zagging the obstacle course of gelled up diesels on the road!
I would normally not recommend the need for any anti gel treatment if you're buying fuel from the local area, but right now in the upper midwest, would be about the only time I'd dump anti gel treatment in the tank.
Or like last month when I fueled up near Vegas and drove to the Wasatch mtns. Went from 60deg to -10. Truck got a dose of PS since I had half a tank of fuel from a warm climate. The trigger was, as one left Vegas getting to St George, stations were advertising "winter conditioned" fuel. Told me the fuel in the desert likely wasn't treated for low temps.
Otherwise, yeah when it's that cold, if the truck is parked in ambient temps, plug it in. Makes starting much easier.
