Perkins fuel systems and engine components can operate on
high sulfur fuels. Fuel sulfur levels affect exhaust emissions.
High sulfur fuels also increase the potential for corrosion of in-
ternal components. Fuel sulfur levels above 0.5 percent may
significantly shorten the oil change interval. For additional infor-
mation, see this publication, “Fluid Recommendations/Engine
Oil” topic (Maintenance Section).

The values of the fuel viscosity are the values as the fuel is de-
livered to the fuel injection pumps. If a fuel with a low viscosity
is used, cooling of the fuel may be required to maintain a 1.4
cSt viscosity at the fuel injection pump. Fuels with a high vis-
cosity might require fuel heaters to bring down the viscosity to a
20 cSt viscosity.

Follow the test conditions and procedures for gasoline (motor).

The lubricity of a fuel is a concern with low sulfur fuel. To deter-
mine the lubricity of the fuel, use either the “ASTM D6078
Scuffing Load Wear Test (SBOCLE)” or the “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 suppli-
er. Some additives are not compatible. These additives can
cause problems in the fuel system.
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.
NOTICE
Heavy Fuel Oil (HFO), Residual fuel, or Blended fuel
must NOT be used in Perkins diesel engines. Severe
component wear and component failures will result if
HFO type fuels are used in engines that are config-
ured to use distillate fuel.
In extreme cold ambient conditions, you may use the
distillate fuels that are specified in Table 26 .
However, the fuel that is selected must meet the
requirements that are specified in Table 25 . These
fuels are intended to be used in operating
temperatures that are down to −54 °C (−65 °F).

The fuels that are listed in this Table may not meet the require-
ments that are specified in the “Perkins Specifications for Distil-
late Diesel Fuel” Table. Consult the supplier for the
recommended additives to maintain the correct fuel lubricity.
These fuels are lighter than the No. 2 grades of fuel.
The cetane number of the fuels in Table 26 must be
at least 40. If the viscosity is below 1.4 cSt at 38 °C
(100 °F), use the fuel only in temperatures below
0 °C (32 °F). Do not use any fuels with a viscosity of
less than 1.2 cSt at 38 °C (100 °F). Fuel cooling may
be required to maintain the minimum viscosity of 1.4
cSt at the fuel injection pump.
