I've got a 94 Dodge Ram 2500 4wd, Cummins diesel. Never had any trouble before (4+ years) with this kind of thing. Running about 50/50 bio & dino, no other additives, and it's been pretty cold here. 0 F 4 nights in a row, and has not been over 22 in more than a week. The engine block heater has been plugged in, but Sunday while on the freeway, it lost power very quickly and died. Got a tow back home, and now it will not start, not even turn over so I believe the battery may be frozen also. Any suggestions on how to thaw the fuel? The engine block heater is plugged in; we don't have a heated shop, not many people do around here. I read that putting kerosene into the tank at about a 1/10 ratio may work to thaw the fuel, any other ideas?
