(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 meth-
od is used. A fuel with a higher cetane number is recommended in order 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 regu-
lations before selecting a fuel for a given engine application. Perkins fuel systems and engine components can operate on high sulphur fuels
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 0.5% may significantly shorten the oil change interval. For additional information, refer to General lubri-
cant Information.
