How old is too old?

Two years ago, I moved to SC from AZ in a 24ft. Penske Truck and my '69 Dart GT in tow. Inside that Dart GT was about 10-15 Gallons of good gasoline. There this gas sat in a closed tank for two years....

Fast Forward to Yesterday....

I finally brought my Dart from the barn I had it in and began to clean it out the best way I know how. I rigged up my siphon pump and started leeching the gas from the Dart into a gas can, via the siphon hose which I rigged one of those cheap clear in line fuel filters into.

While doing this, I had two small particles get caught by the filter and filled the 5 gallon can I had.

My question is this....

Is there and additive or some kind of treatment I can add to this fuel to make is useable again? For whatever reason, we are having fuel supply issues in my area and just dumping this stuff somewhere is time consuming and illegal. I don't want to pay someone to come get it or haul it all to my property 35 miles away, dig a hole and burn it 1 cup at a time, I'd rather use it...

Is there a way that I can?
