To dispose of old gasoline safely and properly, follow these recommended steps:

• Do not pour old gasoline on the ground, down drains, or in regular trash. Gasoline is highly flammable and toxic, and improper disposal can harm the environment and pose safety risks

• Take old gasoline to a Household Hazardous Waste (HHW) facility or collection event. Most cities and counties have designated hazardous waste drop-off locations or special collection days where you can safely dispose of gasoline for free or a small fee

• Use the original or a certified gasoline container for transport. Make sure the container is clean, leak-proof, tightly sealed, and labeled to prevent spills and accidents during transport

• If you have only a small amount, you may let it evaporate safely outdoors. Place the gasoline in a shallow, open container in a well-ventilated area away from ignition sources, children, and pets, and allow it to evaporate completely

• Consider reconditioning old gasoline if you want to reuse it. This involves filtering out particles, separating water, and mixing the treated gasoline with fresh fuel in a 1:5 ratio. However, this is only recommended if the gasoline is not heavily contaminated and you follow safety precautions

• **Never mix gasoline with other automotive fluids like brake fluid or antifreeze, as these mixtures cannot be reused and must be disposed of as hazardous waste

In summary, the safest and most environmentally responsible method is to bring old gasoline to a local hazardous waste disposal site. Check with your city or county government for the nearest facility or collection event. If unavailable, carefully evaporate small amounts outdoors away from hazards
