Alde glycol

Does alde/truma glycol have an expiration date if the bottle has not been opened. I have an extra gallon in reserve and it’s about 2+years old

I just bought a gallon, so a good question. From Google, it's good for at least two years, left sealed up. If you want a better answer, I'd contact Truma/Alde. They usually respond to emails. The bottle has nothing on it pertaining to expiration.

If its not on the label as having an expiration, Its not something I would be concerned with.
