I ran 15w40 all last winter and i forgot to plug my truck in 1 time and she didn't start. It barely turned over, but as soon as i got home and plugged it in for about 1-2 hrs she popped right off. I now run 5/40 syn. I know you said you don't want to run that, so i would go with 10-30 then. My bro runs 10-30 in his 6.0 and never has any problems. The syn is good oil though. It makes the engine run quieter and its supposed to help with mpg. IDK JMO, but i like it.

ive always ran 15-40 and its always popped off even without being plugged in granted it sounds like its only running on cylinder, if you plug it in i wouldn't worry about it one bit, or if your really worried just go start it every couple of hours.

the 1 day when it didn't start was the coldest night we had where i think it hit like -25 and she turned over a few times and then nothing.

I have had it start super rough 1 time and it rocked the whole cab but like you it was on the coldest day of the year. I don't remember how cold it was but it was damn cold
