Old gasoline isn’t just inconvenient; it’s a hazardous material. Improper disposal can contaminate soil and water, pollute the air, and create fire hazards. It’s also illegal. This guide provides a clear, step-by-step process for disposing of old gasoline safely, legally, and responsibly.
Is Your Gasoline Past Its Prime?
Before you worry about disposal, determine if your gasoline is actually bad. Here are some telltale signs:
The Smell Test: Does it smell sour, stale, or “off”? Fresh gasoline has a sharp, distinct odor. Old gasoline develops a noticeably different, often rancid, smell.
Appearance: Is it darker than usual, cloudy, or murky? Does it have sediment or gunk floating around? These changes suggest degradation.
Engine Trouble: Is your engine sputtering, hard to start, or running less efficiently? Old gasoline can cause these issues.
Pure gasoline typically lasts three to six months, while ethanol blends degrade faster, sometimes in as little as two to three months. Storage conditions (temperature fluctuations, air exposure, container type) also significantly impact gasoline’s lifespan.
Safe Handling Procedures
Gasoline is flammable and hazardous. Prioritize safety with these precautions:
Ventilation: Always work outdoors or in a well-ventilated area, away from ignition sources.
No Smoking: Absolutely no smoking or open flames near gasoline.
Protective Gear: Wear gloves and eye protection to prevent skin and eye contact.
Approved Containers: Use only approved, sealed gasoline containers, never food or drink containers. Clearly label the container “Hazardous Waste – Gasoline.”
Disposal Options: A Step-by-Step Guide
Locate a Disposal Site: Contact your local government, fire department, or search online (Earth911) for “hazardous waste disposal near me.” Some auto repair shops or gas stations may accept small quantities, but always call ahead to verify. Your local Department of Environmental Protection website might also have useful resources.
Choose the Right Container: Use a sealed, approved container designed for gasoline, available at hardware or auto parts stores.
Transfer the Gasoline: Work outdoors in a well-ventilated area, away from ignition sources. Use a siphon pump or designated transfer tool to minimize spills.
Handle Spills Immediately: Absorb spills with kitty litter, sand, or a commercial absorbent. Clean the area with soapy water and dispose of contaminated materials as hazardous waste. If gasoline gets on clothing, see step 6 below.
Transport Safely: Place the sealed container upright inside a secondary container (plastic tub, sturdy box) to prevent leaks during transport. Secure the container to prevent shifting.
At the Disposal Center: Follow the facility’s instructions. There may be a small disposal fee.
Other Disposal Methods (Use with Extreme Caution)
Mixing with Fresh Gasoline: Some sources suggest mixing small amounts of relatively fresh, uncontaminated old gasoline with a large quantity of fresh gasoline in a vehicle’s fuel tank. However, this is generally not advised. Experts are divided on its safety, with some believing it likely harms modern engines. Always consult your owner’s manual. This method is not recommended for small engines. Ongoing research suggests there may be long-term damage to engine components that is yet fully understood.
Evaporation (Smallest Amounts Only): For tiny amounts, pour the gasoline into a wide, open metal container in a well-ventilated area far from ignition sources and people/pets. This releases harmful vapors, so it’s environmentally undesirable.
What NOT To Do
Pour Down the Drain: This contaminates water sources and creates a fire hazard.
Pour on the Ground: This poisons soil and can contaminate groundwater.
Put in the Trash: This creates a severe fire hazard.
Burn the Gasoline: This releases harmful pollutants and risks explosions.
Preventing Gasoline Spoilage
Proper Storage: Store gasoline in a sealed, approved container in a cool, dry, dark, and well-ventilated area, away from ignition sources.
Fuel Stabilizer: Add a fuel stabilizer to fresh gasoline to extend its lifespan.
Buy Smaller Quantities: Purchase only the amount you expect to use within a few months.
First In, First Out: Use the oldest gasoline first.
Frequently Asked Questions
How much does disposal cost? Costs vary by location. Contact your local hazardous waste center for pricing.
What if I spill gasoline on my skin or clothing? For skin contact, wash thoroughly with soap and water. For clothing, blot the stain, apply baking soda to absorb the fuel, brush it off, use a stain remover, and wash the clothes without using a dryer, as the remaining fumes could be a fire hazard. Then air-dry the item. Contact a medical professional or poison control if necessary.
Where can I find more information? Contact your local government’s environmental agency, search online resources like Earth911, or consult the EPA.
