i have heard to not use rotella in powerstrokes because it tends to foam.don't have a PS or use rotella so don't know if this is true but i will say this.my 5.9 cummins in my freightliner does not like rotella.smokes like a banshee.delvac no problem,i would use mobil 1 but damn an oil change would cost me 200 bucks.

AFAIK a lot of people use it without reports of foaming.

I have a timer rigged up to run the heater for 3 hours before I leave in the morning. Only use it when really cold. I did try the 5w-40 Mobil1 at one time and it did help starting a bit.

Yes but my truck is not used daily so I don't want to hook it up. I want to be able to leave when I feel like it, hence the switch to 5W40
