Is Sea Foam still okay to use after a few years? [SOLVED]

I have a can of Sea Foam Motor Treatment that is a few years old and was never opened. Is it still okay to use?

Good question, Keith. Yes, Sea Foam Motor Treatment does not have a shelf life so it is definitely still good to use after a few years. As long as the cap is on tight and the fluid is clear, it’s good to use. With the cap on tight, Sea Foam will last decades.
