Three opened partial filled gallon jugs (5 years old) are not worth using. Drop it off at the local city/county recycling place and let them take them out of the car and pick up something on the way home that will let you sleep well. Especially if you have one of the common GMs that came with gaskets the were found out to be incompatible with some ant-freeze compounds. I had two cars with that problem (4.3l V6).
