How long does VP Race fuel stay fresh?

My friend just gave me a bunch of VP Race fuel, the V2 version for 2 strokes. I got 5 gallons in the sealed VP can and another 3 gallons in a plastic VP quick-fill jug. He said he has had it for 6-7 months. I've never used it before and would like to run it through my YZ80. So would it be safe or is the stuff stale?

Thanks for any info!

Thanks for the info. Another race fuel company said the sealed container should be good for many years as long as it stays sealed in metal. The 3 gallons is probably bad because of light passing through the plastic jug.
