Two oils re-refined by technology developed by the Bartlesville Energy Research Center and one commercially re-refined automotive lubricating oil have been subjected to engine test sequences IIC, IIIC, VC, and L-38. Results of these tests and bench-scale evaluations of some physical and chemical properties of these oils are tabulated. The results obtained in this study are believed to represent the first documentation in the United States of the potential performance equivalency of re-refined lubricating oils with lubricating oils derived from virgin feedstocks.
