On the back it says:

And stamped on the bottom back I13165 093 1422 00012204
Can anyone tell me the date they were made?
Check To See That The Oil Jugs You Buy Have The Exact Amount Of Oil In Them And Have An Inner Seal Under The Cap. I Use Mobil 1 And Fram Ultra Filters

If i had to guess i would say it is the last sequence of numbers, made on the 204th day of 2012 or July 24th.

call zerex
In line water heater?
All save energy, but may not save money (complicated, no DIY, parts hard to get, parts expensive). You decide.

Coolant in a sealed container will not go bad, I would not worry about it.

This. As long as the container is sealed, no problem.
