We Tested 3 Engine Oils — The Manual Was Wrong

Mechanics don’t trust 0W-20 oil, and after this lab test, you’ll understand why. We ran the same engine with 0W-20, 5W-30, and 5W-40, logged oil temperatures, analyzed wear metals, and tore the engine down. The results were shocking. One oil ran hotter, thinned out faster, and produced 40% more metal wear. Another stayed stable, cooler, and protected engine components far better — with almost no fuel economy loss. This video explains why owner’s manuals recommend thin oil, how EPA fuel economy regulations affect oil specs, and what mechanics actually run in their own cars. If you want your engine to last 200,000–400,000 miles, this matters. This isn’t about hype. It’s about data, real testing, and long-term engine protection.
