How long does it actually take to break-in the piston ring and cylinder liner? Which one wears - the ring or the liner? We built a CNC spin test rig and used a digital microscope and a profilometer to measure the before and after results. The outcome was unbelievable! Watch to the end to see the answer.

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'm a Tribologist for Total Seal piston rings.
