Multi Tasking Engine Oils
Abstract
Vehicle and equipment systems require a variety of lubricating oils, fluids and greases to satisfactorily operate. The lubricating oils and fluids needed differ widely in their performance because of the intended use and differing system requirements. For example, engine oils and gear lubricants differ not only in viscosity requirements but also in the required additives. Gear lubricants need additives to provide extreme pressure qualities inherent for hypoid gear systems whereas these qualities are not needed for engine oils. Likewise, automatic transmission fluids require a different type of friction modification that is not required for either gear lubricants or engine oils. Additionally, automatic transmission fluids have a greater need for seal conditioners among other things to insure elastomer components do not dimensionally change with use. Obviously, engine oils having multi-purpose applications (e.g., multi tasking) would certainly help to eliminate the types of problems mentioned above. However, the difficulties arise from having to meet multiple engine and other requirements which typically would require increased additive treatment as well as additional types of additives. These higher treatment levels and additives may lead to possible compromises in the oil quality2 as well as potential additive interactions that can be anti synergistic.
