How do you know if motor oil is doing its job? You put it in an engine and subject it to a brutal 50-hour test. Before assembly, every component is carefully measured and tolerances are documented. This establishes a baseline. After the test, every moving component is measured again. The test produces data that the motor oil manufacturer can use to improve their formula. Join Gale Banks as he continues his lubrication education.
