Soot Dispersant Boosters
Soot dispersant boosters prevent the coagulation of soot particles by steric stabilisation. They reduce the viscosity lift which can result from extended soot structures. Larger agglomerates of soot will more easily settle through density differences onto engine surfaces causing piston uncleanliness. Soot dispersant boosters can also stabilise oil insoluble oxidation products preventing the settling of sludge.
