| If its warmer than 10 below I only use cenex roadmaster with archer DPA fuel treatment, I park inside with full fuel at 50 degrees also for 8-10 hrs before leaving again. I do not hesitate to put some 1 in when colder but fuel mileage sux then. Same miles everynight going to Lake Norden it took 15 gal more at a 40/60 to a 50/50 blend. But still cheaper than a towbill. My brother has a 07 dodge cummins, parked outside, plugged in with roadmaster and additive...no 1 fuel. | |
