Lubricant Additives

114 Lubricant Additives: Chemistry and Applications

can be found within the same molecule. Their advantageous physical properties—for example, low
color and odor and good solubility for other additives—make them attractive components for addi-
tive packages. However, although the future looks bright in industrial oil applications in view of
current pressure on sulfur and chlorine (mainly as a result of environmental concerns), the potential
in automotive engine oil remains uncertain due to the current downward pressure on phosphorus.
In fuels, the question is whether the reduced level of sulfur will require replacement by other AW
additives and, if so, whether phosphorus can be incorporated without adversely affecting other
properties (e.g., catalyst effi ciency).
