I would suggest blue marine Stabil at Walmart, etc. Its got more cleaners than the other Stabil products. Shelf life for Stabil is only 2 years once opened, so do not buy a huge container.
Your gas should be good for a year. I would dump any remaining gas into the car/truck in the fall.
The real need for stabilized gas in OPE is for generators. A generator is no good in a blackout if you have no gas. Some blackouts have been regional and there is no gas to be had without driving for hours.
I solved that problem with a propane generator.
