Prestone brake fluid manufacturing date

[tlaspec]

I just purchased some prestone DOT 4 brake fluid and was wondering if anyone knows how I can find out when the fluid was manufactured. The only code I see on the bottle is "M627307"

Brake fluid lasts a long time as long as the bottle is still sealed. Once the seal is broken, it needs to be used quickly (don't save it for the next brake job).

A call or email to Prestone (Honeywell) may be able to tell you something, but I wouldn't count on it.

I bought a yellow dot 3-4 prestone brake fluid, since I own my first car when I was 18, now im 25 and been own more then 8 car, I still use the same bottle to top off brake fluid, I just use it last month on my latest camaro, as long the bottle close tight and storage on cool place, nothing to worried about.

Can moisture go through the plastic bottle and into the fluid over time, say 5 years?
