Depends on how often you cook. If you cook five times a week, I would say change it out every two weeks. Or if it is 1/4" full, then change it out.
Mostly go by how full it is. Just don't leave drippings in there too long as they will eat through the aluminum insert pan and make a mess of your main drip pan.
