What is the shelf life of ATF?
The Valvoline Company does not have a documented shelf life exposure on finished motor oil or ATF. We would expect under optimal conditions that the product would be stable for an extended period of time. We recommend two things: 1) Make sure the rating meets or exceeds your requirements, and 2) Shake the container before use. If the fluid sets, sometimes the additives may settle in the bottom of the container.
