Zinc DialkylDithioPhosphate (AKA Zinc or ZDDP) provides anti-wear protection in motor oils, but the levels of Zinc has been reduced in motor oils over the last 20 years. Because of that, higher Zinc oils and high Zinc additives are now widely available, but is more Zinc actually better? Can you have too much Zinc?

In this video, we worked with Southwest Research Institute, which is one of the leading independent research labs in the world, to test the affects of Zinc levels on both friction and wear, and the results are quite shocking!

Who is the @themotoroilgeek? 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 am the Tribologist for @TotalSeal , and I provide used oil analysis via SPEEDiagnostix.
