Rockets tip re: adding correct amounts of gasoline to fuel is a good one. In 1982, traveling North from Atlanta to St. Louis, I arrived along with a really severe cold front. After parking the car for a time it would barely start and run -- my fuel (purchased in a southern state) was severely gelling or "waxing," it was not formulated for the severe cold!
Addition of a little gasolene saved the day until I could find a diesel pump!
Is gelling normaly a problem in Canada with your Domestic diesel fuel?
