What is the shelf life of Timberline antifreeze coolants?

Our antifreeze coolant products are made with base fluids that combine to form a pH neutral product that has a shelf life of more than three (3) years.  Actually, we believe that the shelf life is ten (10) years or more, but we haven’t been in business that long – we have samples of our original batches of antifreeze that we periodically test to determine this.  Even if the jug has been opened, it’s still good for years.
