Table 2, Operability Requirements
Diesel fuel plays very critical role in the engine fuel injection systems lubrication process. The fuel injection system and fuel pump are protected from wear by the fuel. Some processes used to desulfurize diesel fuel, if severe enough, can also reduce the natural lubricating qualities of the diesel fuel. The use of inadequately lubricating fuel would decrease the life expectancy of the engine fuel injection systems. It is recommended that all fuels used in Detroit™ engines meet the minimum lubricity requirements listed in the above table. Fuels not meeting the lubricity requirements may be additized to meet them.
Premium diesel fuels are not covered by any existing industry specification. It is recommended that the customer obtain additional information from the fuel marketer and compare properties to those listed in the above table before using.
