Why does my Kia Picanto's engine make a knocking sound?

I have noticed that my Kia Picanto's engine has started making a knocking sound while driving. It seems to get worse when I accelerate. What could be causing this and how do I fix it?

There are a few potential reasons why your engine may be making a knocking sound. It could be due to an issue with the fuel injectors or spark plugs, low engine oil levels, or even a problem with the engine bearings. It's best to take your car to a trusted mechanic for a diagnostic check to determine the exact cause.

If you recently had an oil change, it's possible that the wrong type of oil was used or the oil filter was not installed properly, which can cause engine knocking. Make sure to double check the type of oil recommended for your Kia Picanto and have the oil and filter changed if necessary.

Another common cause of engine knocking is using low-quality or contaminated fuel. It's important to always use high-quality gasoline and to also check for any water or debris in the fuel tank.
