The 1980’s — A Decade of Challenge for Engine Oils 811410

The 1980’s will be a decade of challenge toward further development of both engine oils and evaluation techniques to measure their performance properties. Passenger car engine oils will be developed to provide (1) less engine friction, (2) exhaust emission catalyst protection, (3) better engine cold starting, (4) extended oil drain intervals, (5) light- duty diesel performance, (6) more realistic high-temperature viscometrics, (7) compatibility with alternate base oils, fuels and new seal materials and (8) minimum toxic substan­ces. Heavy duty diesel engine oil development will include most of these same performance properties with specific emphasis on the minimization of (1) top land/piston groove deposits, (2) cylinder bore polishing, (3) engine wear, (4) oil consumption, (5) oil thickening, and (6) oil shear loss.
New, more precise engine test techniques will be developed to measure the required engine oil performance parameters through worldwide cooperation leading toward an international engine oil classification system.
