What is the shelf life of Sea Foam Motor Treatment? [SOLVED]

Does Sea Foam Motor Treatment have a shelf life? I’ve had great success with the product in the past and found a couple cans hidden at the back of my workbench that could be four to five years old at a minimum. I thank you in advance for any info you have for me.

Great question Robert!  Sea Foam will stay fresh as long as the cap is sealed.  It’s made from petroleum so it will not change if not exposed to the oxygen atmosphere. If the seal was removed several years ago but the cap was secure, I would not hesitate to use it.  Be sure to verify that the fluid is clear.
