Abstract
Paper summarizes influences on motor oil viscosity, such as shear stability of viscosity modifiers, fuel and/or soot content, and thermal oxidation degradation of oils. Significance of individual aspects was monitored for several motor oils of different viscosity grades during over-the-road service of vehicles powered by spark ignition as well as diesel engines. Trends of viscosity changes were noticed and evaluated.
