API CF
Purchase diesel fuel in small quantities and store in clean, approved containers. Clean fuel prevents the diesel fuel injectors and
pumps from clogging. Do not overfill the fuel tank.
Leave room for the fuel to expand. Immediately clean up any spillage during refueling.
Never store diesel fuel in galvanized containers; diesel fuel and the galvanized coating react chemically to each other, producing
flaking that quickly clogs filters or causes fuel pump or injector failure.
High sulfur content in fuel may cause engine wear. In those countries where diesel has a high sufur content, its is advisable to
lubricate the engine with a high alkaline oil or alternatively to replace the lubricating oil recommended by the manufacturer more
frequently. The regions in which diesel normally has a low sulfur content are Europe, North America, and Australia.
FUEL TYPE
For best results, use only clean, fresh, commercial-grade diesel fuel. Diesel fuels that satisfy the following specifications are
suitable for use in this engine: ASTM D-975 - 1D or 2D, EN590, IS 1460 or equivalent.
FUELS FOR LOW TEMPERATURES
It is possible to run the engine at temperatures below 0°C using special winter fuels. These fuels reduce the formation of
paraffin in diesel at low temperatures. If paraffin forms in the diesel, the fuel filter becomes blocked interrupting the flow of fuel.
Fuel can be: - Summer up to 0°C
- Winter up to -10°C
- Alpine up to -20°C
- Arctic up to -30°C
BIODIESEL FUEL
Fuels containing less than 20% methyl ester or B20, are suitable for use in this engine. Biodiesel fuels meeting the specification
of BQ-9000, EN 14214 or equivalent may be used. DO NOT use vegetable oil as a biofuel for this engine.
Any failures resulting from the use of fuels other than recommended will not be warranted.
AVIATION FUEL
Aviation fuels suitable for use in this engine include JP5, JP4, JP8 and, JET-A (if 5 percent oil is added).
FUEL RECOMMENDATIONS
Fuel with low sulphur content
Fuel with high sulphur content
