What is an engine?
An engine is the heart of your car. It turns fuel into power to get you moving to where you want to go. It’s made up of parts like cylinders, pistons, and valves, all working together to keep things running smoothly.
Common engine issues
Engines can face a few common issues over time:
- Low lubrication: Without enough oil, engine parts wear out faster.
- Oil pump failure: A bad pump means poor lubrication, risking serious damage.
- Old oil: Old oil collects debris, which hurts performance.

How often should you repair your engine?
