2.5 Fuel
Important
•
Use of other types of fuel
could damage the engine.
Do not use dirty diesel
fuel or mixtures of diesel
fuel and water since this
will cause serious engine
faults.
• Clean fuel prevents the fuel injectors from clogging.
Immediately clean up any spillage during refuelling.
• Never store diesel fuel in galvanized containers (i.e. coated with
zinc). Diesel fuel and the galvanized coating react chemically to
each other, producing flaking that quickly clogs filters or causes
fuel pump and/or injector failure.
• Any failure resulting from the use of fuel other than Tab. 2.3, 2.4 will
not be covered by warranty.
Cetane number of 40 minimum. Cetane number greater than 47 is preferred, especially for temperatures
below –20 °C (–4 °F) or elevations above 1675 m (5500 ft.).
