Characterization and Evaluation of Re-Refined Engine Lubricating Oil.

Abstract

This program was conducted to obtain additional data base on the comparative performance of re-refined and virgin oils and to investigate the potential 'substantial equivalence' of re-refined and virgin lubricating oils. The program consisted of: (1) the development of an engine deposit removal, recovery, and analysis methodology. This methodology was used to compare engine deposits derived from virgin and re-refined engine oils. (2) The effects of virgin and re-refined oils on engine blowby composition and engine deposit generation were determined using a spark ignition engine and, (3) Virgin and re-refined basestock production consistency were determined by participating in the ASTM/NBS cooperative basestock consistency study.
