FAKE Oil Claims: The “Lubricity” Test Problem

Do “Lubricity” or "Film Strength" test results correlate to an actual engine? This device was developed almost 100 years ago to evaluate gear oils and greases. Today, many people and products use “film strength” data to make product claims and evaluations, let's see what the science says about this device for motor oils.

I'm a Society of Tribologists and Lubrication Engineers Certified Lubrication Specialist and Oil Monitoring Analyst (I've maintained both of those for over a decade). I also worked for Joe Gibbs Racing for 12 years as their lubricant specialist. During that time, we worked with Wix Filters (one of our sponsors) to test and develop filters for our race engines. We also worked with Lubrizol and Chevron-Phillips Chemical to test and develop oils for our race cars. Following that, I was the head of R&D for Driven Racing Oil. During that time, I formulated and tested over 50 products. We also worked with Cummins, Comp Cams, Oak Ridge National Labs and General Motors on various R&D products. Those efforts are recorded in peer reviewed white papers published by SAE International and ACS Sustainable Chemistry journals. Today, I provide Tribology consulting and used oil analysis via SPEEDiagnostix. #oiladditives #motoroil #camshaft #engine #ZDDP
