Diesel is different than gas in a few respects: Water and Microbes. The water can condensate in the tank with temperature changes and is most often collected in the fuel water seperator filter. Make sure that you drain the water, if it fills, it can stay in the fuel and is potentialy deadly to a diesel engine. The Microbes can grow in diesel fuel and can clog your filters to the point you may have to change them several times. The modern treatments both evaporate excess water and kill then prevent microbes. The microbes are usually only a problem in hot and humid conditions but can happen if the tank is subject to varying temperatures.
<ake sure you get a treatment specific to diesel fuel. It should be listed on the label.
