FuelRecommendations/Specifications
Warning: Do not mix gasoline or alcohol with diesel fuel. This mixture can cause an explosion.
Caution: Due to the precise tolerances of diesel injection systems, it is extremely important that the fuel
be kept clean and free of dirt or water. Dirt or water in the system can cause severe damage to both the
injection pump and the injection nozzles.
Caution: Do NOT use diesel fuel blended with lube oil in engines equipped with a catalytic convertor
(including all model year 1994 and beyond). Damage to legally required emission control may result.
Use ASTM No. 2 D fuel with a minimum Cetane number of 40. No. 2 diesel fuel gives the best economy
and performance under most operating conditions. Fuels with Cetane numbers higher than 40 may be
needed in high altitudes or extremely low ambient temperatures to prevent misfires and excessive
Smoke.
At operating temperatures below 0 ° C [32° FI, use a blend Of No. IDandNo. 2D fuels, also known as
“winterized”
No. 2D.
NOTE: No. 1 D fuel can be used, however, fuel economy will suffer.
Use low sulfur content fuel having a cloud point that is at least 10 degrees below the lowest expected
fuel temperature. Cloud point is the temperature at which was crystals begin to form in diesel fuel.
The viscosity of the fuel must be kept above 1.3 centistokes to provide adequate fuel system lubrication
at 40 °C [104° F].
