Ever wondered if your car's oil life indicator is more of a guess than a guarantee? Discover how accurate oil life indicators really are as we compare used oil analysis results to what the GM Oil Life Indicator predicted. They don't actually test the oil, so how close to correct are they? These test results provide the proof of just how accurate these indicators are. We've got the answers, backed by a detailed used oil analysis test you won't want to miss!

It is worth noting, this engine was already broken-in, so these results do not apply to a brand new engine. For more information on that, check out this video on oil change intervals for new engines:

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. I also own and operate SPEEDiagnostix, which provides used oil analysis.
