Selections of Oils for High-Output Aircraft Engines 370129
THIS paper describes the more conventional methods of selecting an oil for use in high-output aircraft engines. It points out the weaknesses of each and justifies the selection of the engine test at high output as the most reliable criterion.
The necessity for oils of better lubricating quality is established based on experience with high-output engines.
A full-scale engine test of oils is urged not only as a basis for selection of an oil that will permit operation of the engine at high output but for another and equally important reason. It is equally important to determine that the oil selected will not be responsible for high maintenance costs and early and frequent replacement of parts.
The paper endeavors to show that carefully conducted engine tests provide information from which oils can be selected resulting in distinct operating economies and probably improved reliability of operation.
