This what I thought also, Dennis. Years ago I bought on the VW show in
Connecticut 20 original VW Autobahn blue antifreeze gallon cans, $ 1 each,
plus 50 bottles of Techron and 15 bottles of VW brake fluid. Ea. bottle was
$.75. Most were taken to Portugal. A few days ago I looked at the stash and
wondered about the shelf life. Coolant was changed every 2 years.
I added Techron to Westy every thirs fill-up, warned by the TEXACO that the
carbon will find its way into engine oil. I maintained changing Castrol
10-40 oil every 3,000 miles , as suggested by TEXACO.
I understood  the word "outdated ". New formulations will come out. And with
them new "diseases" and side-effects, same as with medicines.

It will probably become outdated long before it goes bad in the bottle. If
it's good for 5 years and 100,000 miles in a cooling system it must be good
forever in the original sealed container.

Has anyone asked anyone a question: "What is that antifreeze shelf life?"
Like the original blue color or pink color VW Autobahn antifreeze
