    Hi, I’m Mike. I’ve spent most of my life around engines. My dad ran a small repair shop when I was growing up in Indiana. I started helping him in the garage when I was a teenager. At first I was just cleaning tools and handing him wrenches. Before long I was pulling apart small engines and learning how everything worked. After studying automotive technology in college, I spent years working in repair shops and dealerships. I’ve worked on everything from everyday car engines to motorcycles and marine engines. Over time I realized that many people feel confused when it comes to engine problems and warning lights. That’s why I created Engines Explained. This site is where I break down engine topics in plain English. No complicated jargon. Just clear explanations that help you understand what’s going on under the hood.
