We just ran some 3-1/2 year old VP C11 on the dyno (from the sealed can) and it ran great. It actually made a tick more power than some other fresh race fuel, so I'd say it wasn't degraded at all. I'd say open it, make sure you don't smell any varnish, and run it. You could always pour a sample out to see if the color changed.

If the fuel isn't oxygenated and it's in a sealed can, I've heard of people running 5+ year old VP fuel without issues. Without access to air or moisture, it can't really react with anything. VP's official stance is it can last up to two years, but their distributors who handle it often will tell you it can go much longer (no guarantees, of course).
