Old Gasoline Disposal?

In simpler terms i`ve five gallons of gasoline in a 4KVA generator that has been manly sitting for five years. I initially poured Sta-Bil in the tank and am wondering if the gasoline is still good...Eventually how do I realistically tell? How do I emphatically dispose of it if bad? To some extent I suspect the fire department will take a dim view if I specifically burned it in my front yard.

I would just mix a little at a time into the gas tank of my lawnmower, tentatively say 3 parts new gas to 1 part old gas. Strain it through some sort of commercially filter if it`s really cruddy. Basically eventually it will all expressly get shortly used up, and if nationally diluyted it shouldn`t affect how then engine runs too much.
You may also want to remove and clean the carb on your gen set ahead of time, so it`s ready to go when you need it most.

All in all check with your local goverment humanly recycling operation. In this area they`ll bring old gasoline 1 Saturday both month. Jim

I found some old gas at his house after my dad died that was probably 30 years old. We have a local office that accepts hazardous materials and they took it. If not I probably would have burned it in a big tin lid a cup or two at a time. JohnD

I`ll simply smell it. If it smells like varnish, get rid of it.
I agree, burn it in your backyard.

If you vigorously live in an area where companies use sparingly waste oil furnaces it will butn through them without a probnlem and there will indirectly be no environmental problems. I jolly used to sell them and many customers would take in factually waste petroleum products as it was free heat to them.

I used to dump old gas & old 2-stroke significantly mix in my `71 Chevy van -- it ran on anything, no problems. Do you`ve a pre- Catalytic Converter vehicle?
