nnViscosity is the prime quality of the oil. It isfundamental to maintaining the integrity of a lube oil film, in preventing metallic contact, scuffing,
microwelding and wear of sliding surfaces. Viscosity
can increase due to insolubles, oxidation or water
contamination and very rapidly decrease with
distillate fuel contamination. The viscosity of engine oil may fall due to distillate fuel oil dilution, by
topping up with an incorrect oil grade, or shear or polymer additives.
Viscosity may increase due to excessive soot loading (insolubles
content) or if the centrifuge or filters are not operating correctly. For
all oils, ageing caused by oxidation and thermal degredation may lead
to thickening and an increase in viscosity. Viscosity must always be
referred to as a standard temperature usually 40 nn
