(1) In order to insure minimum cetane number of 40 a distillate diesel fuel should have minimum cetane index of 44 when ASTM D4737 test
method is used. A fuel with a higher cetane number is recommended to operate at a higher altitude or in cold weather.
(2) Density range allowed includes summer and winter diesel fuel grades. Fuel density varies depending on the sulfur level where high sulfur
fuels have higher densities. Some unblended alternative fuels have lower densities which are acceptable, if all the other properties meet this
specification.
(3) Regional regulations, national regulations, or international regulations can require a fuel with a specific sulfur limit. Consult all applicable reg-
ulations before selecting a fuel for a given engine application. LSD fuel with less than 0.05 percent (≤ 500 ppm (mg/kg)) sulfur is recom-
mended for use in these engine models. Diesel fuel with more than 0.05 percent (≥ 500 ppm (mg/kg)) sulfur can be used only where allowed
by legislation. Fuel sulfur levels affect exhaust emissions. High sulfur fuels also increase the potential for corrosion of internal components.
Fuel sulfur levels above 0.05% may significantly shorten the oil change interval. For additional information, refer to
General lubricant
Information .

The values of the fuel viscosity are the values as the fuel is delivered to the fuel injection pumps. Fuel should also meet the minimum viscos-
ity requirement and the fuel should meet the maximum viscosity requirements at 40° C (104° F) of either the "ASTM D445" test method or
the "ISO 3104" test method. If a fuel with a low viscosity is used, cooling of the fuel may be required to maintain 1.4 cSt or greater viscosity at
the fuel injection pump. Fuels with a high viscosity might require fuel heaters to lower the viscosity to 4.5 cSt at the fuel injection pump.
(5) Follow the test conditions and procedures for gasoline (motor).
(6) The lubricity of a fuel is a concern with low sulfur and ultra low sulfur fuel. To determine the lubricity of the fuel, use the “ISO 12156-1 or ASTM
D6079 High Frequency Reciprocating Rig (HFRR)” test. If the lubricity of a fuel does not meet the minimum requirements, consult your fuel
supplier. Do not treat the fuel without consulting the fuel supplier. Some additives are not compatible. These additives can cause problems in
the fuel system.
(7) Recommended cleanliness level for fuel as dispensed into machine or engine fuel tank is "ISO 18/16/13 or cleaner as per ISO 4406. Refer to
the "Contamination Control Recommendations for Fuels" in this chapter.
(8) Additional limit for fuel containing FAME. Fuel containing more than 2%v/v FAME must meet both tests.
