Engine oils are complex fluids. Each oil on the market today contains a carefully balanced formulation of base stocks and advanced additives selected specifically to meet engine and emission system requirements. Viscosity modifiers also play a major role. Advanced polymer technologies enable more efficient operation, beyond just viscometric control, in increasingly severe environments in the engine compartment. Today’s viscosity modifiers are critical in providing maximum efficiency, durability, cleanliness, and engine protection as components become more and more sophisticated.
