STARTING AND OPERATING 267 Avoid Using Contaminated Fuel Fuel that is contaminated by water or dirt can cause severe damage to the engine fuel system which is not covered by the warranty. Proper maintenance of the engine fuel filter and fuel tank is essential. (See Section 7 for Maintenance Procedures). NOTE: Climatized diesel fuel is a blend of Number 2 and Number 1 Diesel fuel which reduces the temperature at which wax crystals form in the fuel. Bulk Fuel Storage If you store quantities of fuel, good maintenance of the stored fuel is also essential. Fuel contaminated with water will promote the growth of "microbes." These microbes form "slime" that will clog fuel filters and lines. Drain condensation from the supply tank and change the line filter on a regular basis. Fuel Specifications The Cummins Turbocharged, Charge Air Cooled, Diesel engine has been developed to take advantage of the high energy content and generally lower cost No. 2 diesel fuel or No. 2 climatized diesel fuels. Experience has shown that it also operates on No. 1 diesel fuels or other fuels within the specifications in the following chart. NOTE: As sufficient testing has not been completed, organically blended diesel fuels (e.g. biodiesel, ethanol, and methanol blends) are not recommended or approved for use with your Cummins Diesel equipped Dodge Ram Truck. NOTE: In addition, commercially available fuel additives are not necessary for the proper operation of your Cummins Diesel equipped Dodge Ram Truck. NOTE: No. 1 diesel fuel should only be used where extended arctic conditions (-10°F or 23°C) exist. 5
