I'll be traveling to a colder climate for a week soon and currently am using Rotella T6 15w40 syn. Anticipated temps will be in the teens, possibly single digits for low, and 30-40s for the high. I'd prefer to keep the oil in there longer to run this oci out since I barely have like 2k miles on the oil right now. I am more concerned about cold start up wear.
Something to consider: truck has a recall for the block heater (L5P Duramax) so I might not be able to plug in if I can't get the repair in time.
Truck is 2018 Silverado 2500hd L5P Duramax
Thanks in advance
