Why is my Ford Ranger's engine knocking?

My Ford Ranger started making a knocking noise while driving. I'm worried it might be a serious issue. What could be causing this and what should I do?

The knocking noise could be caused by a few different things. It could be a problem with the engine oil, such as low levels or dirty oil. It could also be an issue with the fuel quality or the spark plugs.

I would recommend taking your Ford Ranger to a trusted mechanic to get it checked out. They can diagnose the issue and offer a solution. It's always better to address potential engine problems sooner rather than later.
