Motor oil additives | Anti-friction additive | Super Lubricant | Oil treatment | Viscosity improver | Friction reducer | Metal treatment
Motor Oil Additives, as the name suggests, are treatments which are added to motor oil to serve a specific beneficial purpose. Some motor oil additives change the formulation of the oil to which they are added to enhance lubricity or improve viscosity (e.g Super Lubricant & Friction Reducer or Oil Treatment & Viscosity Improver); some are added to the engine oil to act as an engine cleaner and sludge remover (e.g. Motor Cleaner/Flush) before an oil change; some contain special chemicals which act upon neoprene rubber seals to rejuvenate and condition them, preventing leaks (e.g. Oil Anti-leak) and some merely use the oil as a carrier without changing its formulation, acting instead upon the metal surfaces in the engine (e.g. Engine Restorer and Metal-Tec10 Metal Treatment).
