Component Performance in Engine Oil Formulation 

This article, based on a webinar presentation sponsored by STLE University, provides insight into how and why modern engine oils are formulated and the tests they must pass. We’ll also discuss the appetite for each of these tests for various components—some which improve and some which degrade test results.

The focus is on North American gasoline engine oils. While not exhaustive, this material shows the significant technology that goes into formulating engine oils.
