Caterpillar fuel systems and engine components can operate on high sulfur fuels. However, fuel sulfur levels effect exhaust
particulate emissions. High sulfur fuels increase the potential for internal component corrosion. Fuel sulfur levels above 1.0
percent may significantly shorten the oil change interval. Refer to the TBN and Fuel Sulfur topic in the lubricant's section for
The viscosity limits are for the fuel as the fuel is delivered to the fuel injection pump. Fuels such as JP-8, JP-5, Jet-A-1 or No. 1
diesel fuel have low viscosity. These fuels may require oil cooling in order to maintain a viscosity of 1.4 cSt at the fuel injection
pump. Fuels with high viscosity or cold temperatures may require heating the fuel. Fuel heaters may be required to reduce
viscosity to 20 cSt. For additional information, refer to Special Publication, SEBD0717, "Diesel Fuel and Your Engine".
Low sulfur fuel is commonly used. The treatment that is used to create low sulfur fuel often lowers the fuel lubricity. If the fuel
lubricity does not meet the minimum requirements, consult your fuel's supplier. Do not treat the fuel without consulting with the
fuel supplier. Some additives are not compatible. This can cause problems in the fuel system. See "ASTM D6708" (SBOCLE)
and "ASTM D6079" (HFRR).
In extreme cold ambient conditions, you may use the distillate
fuels that are specified in table 23. However, the fuel that is
selected must have the fuel lubricity that is specified in table
22. These fuels are intended to be used in operating
temperatures that are down to -54C (-65F).

These fuels may not meet the requirements that are
listed in table 22. Contact the supplier for the
recommended additives in order to maintain the proper
