In the cold weather on a lot of days my truck either will not run, or will start and run hard due to jelled fuel. I am originally from Northern Minnesota and in the winter we just simply buy #1 on-road. I have not been able to find a place that sells that in Southern Wisconsin, or Northern IL. Does anyone know any additives that are better than most or where I might be able to find #1 diesel. I am very concerned that this might seriously mess up my lift pump, then my injector pump.
