Christo Lube Shelf Life

[modivin]

For us DIY'ers, is anyone familiar with the shelf life of Christo-lube? It seems to be available in smaller quantities (1/4 oz, 1/2 oz, etc) instead of the 2 oz tube. I service my own regs and just wondering how long it will keep if properly stored....:06:

Mine was several years old when I obtained it a year ago. I used some 2 days ago while rebuilding a couple of my regs.... still seems fine.
