I mixed some Toyota Red LLC coolant with distilled in advance and its on the shelf. Plan to use if for top offs and a drain and fill next year or 2. What is the shelf life? Is it aging?
 
"a year or two" is nothing....It should be fine for at least a few years more than that, IMO.
 
If it is in the original container and the cap is replaced tightly it should last for a very long time.

It is only when it is in service does it take a beating, even then it lasts for half a decade.

+1 ^
Isn't it funny though, how much longer, "Half a decade" sounds than "5 years"? or is it just me?

Research says its all about air. The jugs mixed 50/50 are full and caps are tight so I'm good, thanks for the responses.
