Do Oil Catch Cans Actually Work?

About

How do cars work? It's a simple question, without a simple answer. That's what this channel is for! You could search the web endlessly for consumable information, or you can watch my simple to understand videos. I'm a graduated mechanical engineer with a passion for cars, and my goal is to help other people passionate about cars learn how they work. Hope you find my videos enjoyable; feel free to ask questions! New videos every Friday. Jason Fenske - Channel Owner - Engineering Explained
