Why does my Ford S-Max's engine sound louder than usual?

I recently purchased a used Ford S-Max and I've noticed that the engine seems to be making a louder noise than it did when I first got it. It doesn't seem to affect performance, but I'm worried it might be a sign of a bigger issue. Should I be concerned?

It's possible that there is an issue with the muffler or exhaust system. It's best to have a mechanic take a look at it to be sure.

Have you checked the oil level and quality? A low or dirty oil can sometimes cause louder engine sounds.

It could also be an issue with the engine internals, such as a worn out bearing or valve. Get it checked out by a mechanic to avoid any potential problems down the road.
