Does Fuel Additive Have A Shelf Life If Opened?

[Mad Maxx]

I have some Silver Jug Power Service Leftover from the End of Last Year when it was still Warm enough to Use it, then it got Cold really Quick, and before I could use it, I had to go to the White Bottle.

Will it still be Good this Year or does it go Bad?

Same with the White Bottle stuff I got now. I have 2 Jugs and it's Starting to get Warm, and I won't be able to use it all before I go back to the Silver Bottle.
