- composition which comprises a fatty acid alkyl ester.
- a diesel fuel composition used to fuel a compression ignition engine may incorporate a fatty acid alkyl ester (FAAE) such as a fatty acid methyl ester (FAME) as a fuel component.
- FAME fatty acid methyl ester
- FAME is much less volatile than conventional diesel so has a much higher tendency to accumulate in the lubricant relative to fossil-derived diesel fuel. Consequently, higher levels of FAME in diesel fuel can lead to higher level of fuel dilution in the lubricant, which can lead in turn to an undesirable loss in viscosity of the lubricant.
