The SAE Oil Labeling Assessment Program-Third Year Progress Report

This paper briefly reviews the scope of the Oil Labeling Assessment Program (OLAP) and the planning involved in conducting the program. The results of analyses on 148 samples of engine oils that were purchased at retail in the fall of 1988 are presented and discussed. All samples were labeled SF or SG, separately or in combination with a C category designation. A comparison of these results with those obtained in previous years is presented. Additionally, nine engine oils previously sampled and found to be questionably labeled were resampled and analyzed. These results are discussed.
