DON’T Choose By BRAND Name…

What is the right way to choose an oil? Well, it doesn't start with choosing a brand name. Instead, the application will dictate the chemistry needed. A 750 HP race engine needs a racing oil, not a passenger car oil or diesel oil. A non-synchronized transmission needs a different fluid than a synchronized transmission does, especially if it has brass synchronizers. A hypoid rear gear may or may not have a limited slip differential, which impacts the choice of chemistry needed (limited slip differentials need a limited slip gear oil). As you can see, each of these applications requires a different chemistry, and none of these decisions begin with a brand name. In this video I'll show you how I choose the engine oil, transmission fluid and gear oil for my Dad's vintage NASCAR race car. He's 76 years old and the engine makes over 750 horsepower, so I have to get these choices right. After making these choices, we will go to the racetrack and see how the car runs. Plus, we will see how much difference a smaller carburetor makes in terms of average lap time! Here's one of the best FREE resources on lubricants: https://petrocanadalubricants.com/en-...

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. #oilchange #motoroil #oilfilter #engine #syntheticoil #oilanalysis #gearoil #transmissionfluid
