20W50 vs 5W20 Which Oil Protects Better

Which viscosity provides the best protection - a 20W-50 or a 5W-20? Which one delivers the lowest friction? Since friction and wear are independent of each other, we need a special engine equipped with combustion analysis to separate engine friction from the horsepower created by combustion. To measure wear, we need used oil samples of both oils to measure the wear generated in the engine during start-up cycles and full power runs. To isolate just the effect of viscosity, we choose two oils that have the exact same additive package and base oil types. This way, the only variable is the viscosity. • While we had the engine on the dyno, we also tested the impact of pre-filling (or not pre-filling) the oil filter on engine wear, and that produced an unexpected result! • To get to the sections you are most interested in, here are the chapter shortcuts: • 00:01:04 - Combustion Analysis vs Dyno Horsepower Readings • 00:02:48 - Test Plan • 00:08:07 - Oil Pressure Rise with 5W-20 • 00:14:53 - Dyno Testing - 5W-20 Oil • 00:16:37 - Cold Pour Comparison - 5W-20 vs 20W-50 • 00:19:45 - Oil Pressure Rise with 20W-50 • 00:20:50 - Dyno Testing - 20W-50 oil • 00:21:56 - OIl Level Testing • 00:27:03 - Power Test Results - 5W-20 vs 20W-50 • 00:30:33 - Wear Test Results - Oil Analysis Reports • For more about Oil Analysis, check out: https://www.speediagnostix.com • For a deeper dive into the science of lubrication, check out my good friend Rafe Britton's channel @LubricationExplained • For more information about EFI University, check out: http://www.efi101.com • Here are links to the products used in the video: • GP-1 20W-50 https://amzn.to/3VsZc9J • GP-1 5W-20 https://amzn.to/3yOzC6q • Wix Racing Filter https://amzn.to/4bJLK77 • To see how friction and wear are independent of each other, check out this video: • • More Zinc = More Wear?

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. • As an Amazon Associate I earn from qualifying purchases That just means that I may earn a small commission, at no cost to you, if you choose to purchase that product from Amazon.com.
