Most municipalities have some type of hazardous waste recycling facilities where you can dispose of old gasoline.
You could probably also take it to an auto mechanic. Depending on the amount, they may dispose of it for you for free.
Assuming you are talking about a small amount of fuel, you could put it in your vehicle's fuel tank. Just make sure the tank is at least 3/4 full when adding the old fuel. The small amount of old gas will mix with the newer gas in the car and won't hardly make a difference.
I pour it in holes drilled in tree stump, to be burned.
While the gas is considered "old", it will still work in your lawn mower. It is not recommended that you use old gas, however I prefer not to waste that liquid gold.
