Fuels, Lubricants, and Coolant Diesel Fuel Consult your local fuel distributor for properties of the diesel fuel available in your area. Fuel lubricity should pass a minimum of 3100 gram load level as measured by the BOCLE scuffing test. In general, diesel fuels are blended to satisfy the low temperature requirements of the geographical area in which they are marketed. Sulfur content: Sulfur content should not exceed 0.5%. Sulfur content less than 0.05% is preferred. If diesel fuel with sulfur content greater than 0.5% sulfur content is used, reduce the service interval for engine oil and filter by 50%. DO NOT use diesel fuel with sulfur content greater than 1.0%.
Diesel fuels specified to EN 590 or ASTM D975 are recommended. In all cases, the fuel shall 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). Bio-diesel fuels may be used ONLY if the fuel properties meet DIN 51606 or equivalent specification. DO NOT mix used engine oil or any other type of lubricant with diesel fuel. Cold Filter Plugging Point (CFPP) below the expected low temperature OR Cloud Point at least 5 ° C (9 ° F) below the expected low temperature.
OURGP11,000018C –19–12FEB04–1/1 Lubricity of Diesel Fuel Diesel fuel must have adequate lubricity to ensure proper operation and durability of fuel injection system components. these fuels also adversely affects injection pump seals and may result in leaks. Use of low lubricity diesel fuels may also cause accelerated wear, injection nozzle erosion or corrosion, engine speed instability, hard starting, low power, and engine smoke. ASTM D975 and EN 590 specifications do not require fuels to pass a fuel lubricity test. Sulfur content of diesel fuel for highway use is less than 0.05% (500 ppm) in the United States and Canada, and less than 0.035% (350 ppm) in the European Union.
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 or ISO 12156-1. Experience shows that some low sulfur diesel fuels may have inadequate lubricity and their use may reduce performance in fuel injection systems due to inadequate lubrication of injection pump components. The lower concentration of aromatic compounds in If fuel of low or unknown lubricity is used, add John Deere PREMIUM DIESEL FUEL CONDITIONER (or equivalent) at the specified concentration.
