(1)
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 or international regulations can require a fuel with a specific sulfur limit. LSD fuel with less than 0.035 percent (≤ 350
ppm (mg/kg)) sulfur is strongly recommended for use in these engine models. Diesel fuel with more than 0.035 percent (≥ 350 ppm (mg/kg))
sulphur can be used only where allowed by legislation. Fuel sulfur levels affect exhaust emissions. High sulfur fuels also increase the poten-
tial for corrosion of internal components. Fuel sulfur levels above 0.035% may significantly shorten the oil change interval. For additional in-
formation, refer to General lubricant Information.
(4)
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,
"ISO 3104" test method or the "IS 1448" test method. If a fuel with a low viscosity is used, cooling of the fuel may be required to maintain 2.0
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.
NOTICE
Operating with fuels that do not meet the Perkins rec-
ommendations can cause the following effects: Start-
ing difficulty, poor combustion, deposits in the fuel
injectors, reduced service life of the fuel system, de-
posits in the combustion chamber, and reduced serv-
ice life of the engine.
Note: The owner and the operator of the engine has
the responsibility of using the fuel that is prescribed
by the Central Pollution Control Board of India
(CPCB) and other appropriate regulatory agencies.

Cetane Number
Cetane number is a measure of the ignition quality of
diesel fuel. Fuel that has a higher cetane number will
give a shorter ignition delay and will produce a better
ignition quality.
Cetane numbers are derived for fuels against
proportions of cetane and heptamethylnonane in the
standard CFR engine. Refer to "ISO 5165" for the
test method.
