What is an Ashless Dispersant oil?
Ashless Dispersant oils are formulated from base stocks blended with additives designed with a range of objectives which may include enhancing low temperature fluidity, high temperature stability, corrosion inhibition and anti-wear protection. The additive system is ashless and of a dispersant nature offering greater engine cleanliness. Ashless means that the product does not contain any metallic components – this is important because it reduces the formation of harmful metallic ash deposits within the engine. Dispersant means it will hold small particles in suspension if they do not dissolve, allowing these particles to be carried away from critical areas and filtered out. This helps keep the engine clean. Ashless Dispersant piston engine oils are approved against SAE J1899 specification (superseding MIL-L-22851D).
