Group 02 Fuels, Lubricants, and Coolant DIESEL FUEL Consult your local fuel distributor for properties of the diesel fuel available in your area. • 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% is used, reduce the service interval for engine oil and filter changes by 50%. — DO NOT use diesel fuel with sulfur content greater than 1.0%. 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.
02 1 Bio-diesel fuels meeting DIN 51606 or equivalent specification may be used. In all cases, the fuel must meet the following properties: • Cetane Number 40 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. RG,FUEL1 -19-22FEB95 LUBRICITY OF DIESEL FUELS Diesel fuel must have adequate lubricity to ensure proper operation and durability of fuel injection system components.
Fuel lubricity should pass a minimum of 3300 gram load level as measured by the BOCLE scuffing test. Diesel fuels for highway use in the United States now require sulfur content less than 0.05%. Diesel fuel in the European Union will require sulfur content less than 0.05% by 1 October 1996. ASTM D975 and EN 590 specifications do not require fuels to pass a fuel lubricity test. Diesel fuels meeting U.S. Military Specification VV—F—800E pass a fuel lubricity test. 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 injector components.
The lower concentration of aromatic compounds in these fuels also adversely affects injection pump seals and may result in leaks. If fuel of low or unknown lubricity is used, add John Deere ALL-SEASON DIESEL FUEL CONDITIONER or equivalent at the specified concentration. 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.
