If you are like me, you probably have a several bottles of "new" oil in your garage, but they have probably been there for a while. Like a gallon of milk in your refrigerator, does a bottle of motor oil have an expiration date? Unfortunately, I've never seen a "use by" date on a bottle of oil, so how can you know if your "new" oil has gone "bad"?

In this video, I'll show you two simple ways to test your unused oil at home to see it is still safe to use.

Here are the links to the products I used to do the tests.

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 ChevronPhillips 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.
