Old fuel disposal or use ?

Add a few gallons at a time to a tank with several gallons of good gas. It'll burn. I used to do this on my carbureted, no cat con step van engine. I did it often, as I used to run a mobile small engine biz, and the number one repair was cleaning out old gas, which I then had to get rid of.
I can't speak to something that has smog stuff and/or a computer.

I am lucky. I have an old tractor LOL. I mix no more than about 1:4 at a time, 1: bad has to 4: fresh

I also use it to clean parts. I even do that with 2 stroke gas. A little oil in the fuel doesn't hurt a thing!!!

Flat tire earlier this summer, that backhoe makes a great jack!!
