Testing Shows 16 Percent of Oils Fail API SM Specification

According to the Institute of Materials (IOM), testing shows that of the 250 off-the-shelf motor oils that claim to meet the API SM specification, 16 percent do not. According to Mary Herrmann, IOM general manager in Midland, Mich., 40 motor oils failed at least one of the specification limits.

"This shows the challenge for API,” said Herrmann. “They also gather samples from the marketplace and do testing, but we're still seeing oils that are off-spec which carry the ILSAC and API marks on the labels.”

AMSOIL synthetic motor oils meet or exceed minimum API SM specifications, and the company’s rigorous quality control program ensures each quart delivers superior protection and performance.
