Don't laugh, but its going to get down to 15 next week here and yes in my neck o' the woods we start acting crazy when that happens. So do I need to run out to the farm and add the non-gelling additive to my tractor or is that only for those that are planning on working their rig during those temps? If I know I wont be firing it up until another week from those temps, where the forecast is calling for it to get back up to 50s-60s, do I need to fool with adding it? its it bad for it gel then ungel? Ill make the drive if its better to add it. Some say you don't even need it. This is my first winter as a tractor owner so I'm still learning. Thanks for support.
