Discussion of the rotary-combustion engine's history, operation, and lubrication illustrates the role of various quality level engine oils in providing the necessary functions of engine seal wear protection, bearing lubrication, rotor cooling, and overall combustion chamber area cleanliness. Specific examples of current quality and experimental-type engine oil influence on overall engine durability, including seal and housing surface wear, are cited for various engine designs. Data evaluating lube oil effects on engine cleanliness and oil consumption characteristics are also discussed. Analysis of used oil from a number of test engines is presented showing the rotary-combustion engine to yield oil deterioration typical of current piston engines.
