First off, I apologize for the slightly off topic question... I have a case of Prestone Antifreeze/Coolant that I estimate to be between ten (10) and fifteen (15) years old, and would like to know the shelf-life of this product?
The antifreeze is on a basement shelf in retail sealed gallon containers and has always been kept in a clean, cool, and dry environment. Is this coolent safe to use in my Explorer or should I have it recycled?
Thank you,
Steven
