FUEL REQUIREMENTS (DIESEL ENGINES)
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 pro-
vide 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.
Diesel fuel is seldom completely free of water. To
prevent fuel system trouble, drain the accumulated
water from the fuel/water separator using the fuel/
water separator drain provided. Use an approved fuel
container to catch drainage and dispose of per local and
governmental regulations. If you buy good quality fuel
and follow the cold weather advice above, fuel condition-
ers should not be required in your vehicle. If available in
your area, a high cetane “premium” diesel fuel may offer
improved cold-starting and warm-up performance.
