Does motor oil have an expiration date? How long is it generally good for?

Valvoline motor oil does not have a documented expiration date. Under optimal conditions, the product is stable for an extended period of time and can be used as long as the American Petroleum Institute (API) rating on the label continues to meet or exceed the requirements listed in your owner's manual. If the rating is still current, shake the container before use to blend any additives that may have settled.
