What can I look forward to once winiter really sits in? Who treats their fuel above and beyond the typical 'winter blend' which most northern fuel sources do. I live in central NY. I'm an ex trucker, and dispatcher, so I'm looking ahead towards winter and daily care and feeding of my office van. I've got an '04 118" wb window van (I would say passenger, except I doubt it ever had passenger seats) in it. I'm running about 200 miles a day currently, putting in two tanks of fuel per week, I expect it will be about the same straight through winter. Anyone have a favored fuel treatment if you use one at all? Thanks for looking!
