[Johnb]

Would appreciate information on the shelf life of (unused):

Automatic transmission fluid. Pennzoil
Shell Rotella T4 15W-40 engine oil
Prestone Dexcool. Some has been diluted 50/50 with distilled water and some not

Thanks

Google is your friend:

search "shelf like of ________________" Lots of info.

I'm not sure but I suspect you'd get more authoritative info.

My guess is they will live longer than any of us, but as Don said, Google it. Let us know what comes up please!
