Engine Oil Oxidation correlation of the ASTM III-D and III-E Sequence Engine Tests to Bench Tests 892164

Four bench oxidation tests, the penn state microoxidation test, the thin film oxygen uptake test (TFOUT), ASTM D-2112 and ASTM D-2272 rotating bomb tests (RBOT), were evaluated for their ability to predict the oxidation performance of motor oils in the ASTM Sequence III-D and III-E engine tests. Based on comparative results for a series of oils for which we have III-D, III-E or other engine test data, the Penn State microoxidation test gave the best overall prediction.
