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. Perkins fuel systems and engine components can operate on high sulphur
fuels. 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 this manual, Sulfur section, and serv-
ice interval with high sulphur fuel.

A minimum 45 cetane number is recommended for operations in cold weather below 0° C (32° F)ambient and high altitude.

“Via standards tables, the equivalent API gravity for the minimum density of 801 kg / m
3
(kilograms per cubic meter) is 45 and for the maxi-
mum density of 876 kg / m

is 30”.
