About this channel

As a Certified Lubrication Specialist with over 20 years experience, The Motor Oil Geek channel delivers real data about motor oils from an expert perspective instead of speculation. Twice each month I will upload a new video that either analyzes a new oil, dyno tests an oil, reveals the details about motor oil chemistry or uncovers the history of motor oil. Utilizing the same technology applied by Formula 1 teams, The Motor Oil Geek uses SPEEDiagnostix to analyze our new and used oil samples. It's my mission to provide results that allow you to make decisions based on data, not speculation. The internet is full of people who claim to know about oil and lubrication. At The Motor Oil Geek, you get an actual industry expert with championship winning experience and the credentials to back it up. Our motto is Science, Not Speculation. If you know what size wrench is needed to change your oil, this channel is for you!
