Living in North Carolina we don't frequently see extremely low temps but last year we had a few weeks that went as low as 8 degrees. I don't think they sell winterized diesel here, at least I can't find anything that says they do. I'm wondering at what temp should I use and anti-gel supplement? Also, I always run 2-stroke oil in my fuel. Is it safe to run anti-gel with the 2-stroke when necessary?
