No worries Bob. A sealed can of Sea Foam Motor Treatment will last several decades. An open can that is capped tight will last a few years. Even so, does best when used in fuel and oil systems. Use it up!

Does Sea Foam go bad in an un heated garage over the winter?

No, Sea Foam is not affected by extreme cold (think -40 degrees F), so it’s fine in an unheated garage.
