Fuel - Kohler KDI 1903M Workshop Manual

VISCOSITY
WITH SPECIFICATIONS
• Low S.A.P.S. oils, sulfate ashes <1% may not be used with fuels with a sulfur content >50ppm.
• Filtration of oils is critical to proper operation and lubrication; always change filters regularly as
specified in this manual.

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.
Any failures resulting from the use of fuels other than recommended will not be warranted.
•
Warning
• 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.
NOTE: In a warranty case the customer must prove by a certificate from the fuel supplier that an allowed
fuel was used.
KDI Mechanical Injection Tier 3, Tier 4 Final – Stage IIIA, Stage IIIB, Stage V certified Engines (w and
w/o EGR)
• Those engines are designed for fuels in accordance with EN 590 and ASTM D975 for a cetane number
of at least 45. Since those engines are not equipped with exhaust gas after-treatment, they can be
operated with diesel fuels with sulfur content up to 500 mg/kg (ppm). Compliance with the emission
requirements is guaranteed only with sulfur content up to 15 mg/kg (ppm).
Engines operated with fuels as per EN 590 and ASTM D975 with sulfur content < 15mg/kg have an oil
changing interval of 500hrs. Fuels with a sulfur content > 500 mg/kg demand a shorter lubricating oil
