264 STARTING AND OPERATING ENGINE RUNAWAY WARNING! In case of engine runaway due to flammable fumes from gasoline spills or turbocharger oil leaks being sucked into the engine do the following to help avoid personal injury and/or vehicle damage: 1. Shut off engine ignition switch. 2. Using a CO2 or dry chemical type fire extinguisher, direct the spray from the fire extinguisher into the grille on the passenger side so that the spray enters the engine air intake. The inlet for the engine air intake is located behind the passenger side headlamp and receives air through the grille FUEL REQUIREMENTS Use good quality diesel fuel from a reputable supplier in your Dodge truck. For most year-round service, No. 2 diesel fuel meeting ASTM specification D-975 will provide good performance. If the vehicle is exposed to extreme cold (below 20°F or -7°C), or is required to operate at colder-than-normal conditions for prolonged periods, use climatized No. 2 diesel fuel or dilute the No. 2 diesel fuel with 50% No. 1 diesel fuel. This will provide better protection from fuel gelling or wax-plugging of the fuel filters. WARNING! Do not use alcohol or gasoline as a fuel blending agent. They can be unstable under certain conditions and hazardous or explosive when mixed with diesel fuel.
