Over the years I have pulled a lot of Blue Goo out of Vanagon engines. I see no real benefit of that coolant. There are other newer, better choices out there.
Techron is really designed to remove deposits from the outside of the injectors and back of the intake valves and guides. The Waterboxer engine does not suffer from this fate unless the engine is passing excessive blow by or the intake valve guides are worn. Techron should not be used more the 2x per oil change as it can dilute the oil.
Conventional 10w-40 oil is not the best choice for the Waterboxer, especially for extended high speed driving. 20w-50 or Synthetic equivalent like Mobil-1 15w-50.

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I understood the word "outdated ".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It will probably become outdated long before it goes bad in the bottle.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
