About the Founder

Hi, I’m Peter Mytko, the founder of Car Guru DIY.

For me, cars aren't just transportation they're a lifelong obsession. I'm a self-taught mechanic and lifelong enthusiast who firmly believes that everyone should feel confident opening their own hood.

My journey started not in a fancy school, but underneath my own vehicles. I’m a passionate, self-taught DIY mechanic who has spent years earning my knowledge through grease and effort.

Car Guru DIY was created to make automotive knowledge more accessible. A lot of useful information in the car world is either scattered, overly complex, or locked behind technical language. This platform is my way of bringing it together in a clearer, more practical format. When I'm not in the garage, I'm often driving around the UK, hunting down the most interesting car-connected stories and spots which often end up right here on the blog!
