Fuels, Lubricants and Coolant
Diesel Fuel
Consult your local fuel distributor for properties of the diesel fuel available in your area.
In general, diesel fuels are blended to satisfy the low temperature requirements of the
geographical area in which they are marketed.
Diesel fuels specified to EN 590 or ASTM D975 are recommended.
Required Fuel Properties
In all cases, the fuel must meet the following properties:
Cetane number of 45 minimum. Cetane number greater than 50 is preferred, especially for
temperatures below -20°C (-4°F) or elevations above 1500 m (5000 ft).
Cold Filter Plugging Point (CFPP) below the expected low temperature OR Cloud Point at
least 5°C (9°F) below the expected low temperature.
Fuel lubricity should pass a minimum load level of 3100 grams as measured by ASTM D6078
or, maximum scar diameter of 0.45 mm as measured by ASTM D6079.
Sulfur Content:
• Diesel fuel quality and fuel sulfur content must comply with all existing regulations for
the area in which the engine operates.
• Sulfur content less than 0.05% (500 ppm) is preferred.
• If diesel fuel with sulfur content greater than 0.05% (500 ppm) is used, crankcase oil
service intervals may be affected. (See recommendation for Diesel Engine Oil).
• DO NOT use diesel fuel with sulfur content greater than 1.0%.
IMPORTANT: DO NOT mix used engine oil or any other type of lubricating oil
with diesel fuel.
