Selecting New Formulation of Industrial Gear Oil - Focus on EP Performance

摘要

To replace an expensive and partially obsolete component-blend formulation of Engen's industrial EP gear oils, several additive-package formulations were tested and compared with other oil companies' products. Some of the tests were done at the Tribology Laboratory in the Department of Chemical Engineering, University of Pretoria. The paper covers the methodology used and the main results - with particular focus on the innovative 30-hour extended FZG test.
