Okay. Do not run the engine any longer until we confirm a few things. If you just had an oil change done then we need to check the oil and make sure they put oil in it and enough.
Here is a guide that talks about how to check it towards the bottom if you are not sure:

No matter what we find, we need to take this back to who did the oil change ASAP and you need to tell them it has been doing this ever since. That is definitely an engine knock or tap. It sounds like the upper end but as I said, if this started just after the oil change then they are potentially responsible. The more time that goes by, the more opportunity they have to say they didn't cause it.
If I am correct, the engine may need to be replaced as that noise is caused by a bearing in the engine not having oil on it and it is metal to metal. That is why we cannot delay in getting this back to them because they would be responsible for replacing the engine if they caused it.
Let me know if you have questions.
