Disposal at HHW collections costs your municipality more than you paid for it. It is best to use gasoline up before it spoils. If treated with Sea Foam or other gas stabilizer, it can last up to a year.
Spoiled gasoline is flammable, and must be brought to the Braintree Household Hazardous Waste Event.
Antifreeze and Motor/Fuel oil (free of water, gasoline and other contaminants) are accepted at Braintree’s Household Hazardous Waste Event
