It's not a matter of "can" you wear oxfords with jeans, but "should".

Oxford shoes are very formal shoes. They have a distinct toe shape, which makes them very formal and stylish. You can wear oxfords with jeans, but it's definitely not the best look for you.

You should wear sneakers or casual shoes instead of oxfords. This will make you look more casual, which is what you should be going for if you're trying to wear oxfords with jeans.
