I Have Always Wondered??? For Example 'AL 80' Fill To 3000 Psi . How Long Is The Air In The Tank Good For . Lets Say You Havent Dove In 3 Months .would The Air Go "bad" ??????? I Have Always Use Mine Up With In A Weeks Time .
 
As long as there is no corrosion in the tank,it stay's good forever.
Well atleast for many years,recently used one of my older tanks,hadn't been used for 5 years and the air was still fine.One problem though,now the tank needs a new hydro,being used only once.:D

I agree. Nothing in air spontaneously decays, and there is not much that can occur in the way a chemical reaction with stuff on the inside of the tank. My guess is that it would be good for a long, long time.
