Reusing Peanut Oil

Ok, so I'm frying a turkey for Thanksgiving this year ... Now, about the only time I use my fryer is the Thanksgiving turkey to cook! I know that you can reuse the peanut oil after it was heated ... But how long will it keep? Next Thanksgiving? Or does it go wrong now?

Sorry, but it goes bad very quickly, even in the refrigerator, partly because of the meat gravy / in it (because of Turkey). You can keep more than three weeks in the refrigerator * *.
