Cool, I'm in the same boat, never had an issue, don't want to..... I run the white bottle PS. But I have never plugged in. Usually not that cold tho.I've never actually had it fail to start, I just don't like cold starting if it's below 0F if I can help it. I do run PS +cetane boost in my fuel in the winter and I keep fuel filters and diesel 911 with me just in case.
