336 MAINTAINING YOUR VEHICLE WARNING! Do not use alcohol or gasoline as a fuel blending agent. They can be unstable under certain conditions and be hazardous or explosive when mixed with diesel fuel. NOTE: Due to lack of lubricants in alcohol or gasoline, the use of these fuels can cause damage to the fuel system. Hence, use of these fuels will void the warranty on the engine. NOTE: As sufficient testing as 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. Maintenance Free Batteries The top of the maintenance free batteries are permanently sealed. You will never have to add water, nor is periodic maintenance required.
