How Do I Get Rid of Old Gasoline?
Old gasoline, often identified by its varnish-like smell, gumming residue, and poor engine performance, requires responsible disposal to protect the environment and prevent hazards. Safe disposal methods primarily involve taking the fuel to a designated hazardous waste collection facility or mixing small quantities with fresh gasoline for use in compatible engines, always adhering to local regulations and safety precautions.
Understanding the Dangers of Old Gasoline
Gasoline, a complex mixture of hydrocarbons, deteriorates over time due to oxidation and evaporation. This process creates gum and varnish-like substances that can clog fuel systems, leading to engine starting problems, reduced performance, and potential damage. Moreover, old gasoline becomes less volatile, meaning it doesn’t ignite as readily, further hindering engine function. Leaving it unattended poses significant fire hazards and can contaminate soil and water sources. The volatile organic compounds (VOCs) emitted contribute to air pollution.
Safe Disposal Methods for Old Gasoline
There are several methods to safely dispose of old gasoline, each with its own advantages and considerations. Your choice should be guided by the quantity of gasoline, local regulations, and the resources available to you.
Hazardous Waste Collection Facilities
This is generally the safest and most environmentally responsible option. Most municipalities offer designated hazardous waste collection facilities or events where residents can dispose of materials like old gasoline, oil, paint, and other potentially harmful substances.
- Finding a Facility: Search online for “hazardous waste disposal near me” or contact your local government’s environmental services department for a list of approved facilities and their operating hours.
- Transportation: Transport the gasoline in approved, sealed containers designed for flammable liquids. Ensure the containers are clearly labeled as “Old Gasoline” to avoid any confusion. Avoid transporting large quantities at once. Secure the containers in your vehicle to prevent spills during transit.
- Cost: Some facilities may charge a small fee for disposal, while others offer free collection days or events.
Mixing with Fresh Gasoline (For Small Quantities)
In some cases, small quantities of old gasoline can be mixed with fresh gasoline and used in compatible engines. However, this method requires careful consideration and is not suitable for all situations.
- Ratio: The recommended ratio is typically no more than 1 part old gasoline to 10 parts fresh gasoline. Exceeding this ratio can negatively impact engine performance.
- Engine Compatibility: This method is best suited for older, less sensitive engines. Modern engines with sophisticated fuel injection systems may be more susceptible to problems caused by old gasoline. Consult your vehicle’s owner’s manual for guidance.
- Fuel Stabilizer: Adding a fuel stabilizer to the mixture can help to minimize the negative effects of the old gasoline.
- Storage: Avoid storing the mixed gasoline for extended periods, as the old gasoline will continue to degrade the fresh gasoline.
Other Disposal Options (Less Common)
In some specific circumstances, other disposal options may be available, but these are often less common and require extra caution.
- Burning (With Proper Permits and Equipment): Burning gasoline is highly discouraged due to the release of harmful pollutants and the risk of uncontrolled fires. However, some industrial facilities or specialized waste disposal companies may have the necessary permits and equipment to safely incinerate gasoline. This is usually only an option for large quantities.
- Donation (Rare): Occasionally, automotive repair shops or training facilities may accept donations of old gasoline for instructional purposes. Contact local shops to inquire about their policies. Be sure to follow all safety precautions when transporting the gasoline.
- Commercial Disposal Services: Professional waste disposal companies can handle the safe and legal disposal of hazardous materials, including old gasoline. This option is typically more expensive but may be necessary for large volumes.
FAQs About Old Gasoline Disposal
FAQ 1: How can I tell if my gasoline is old?
The most obvious sign is a distinct varnish-like or sour smell. Old gasoline may also appear darker in color and contain sediment or gum-like deposits. It may also cause engine starting problems, rough idling, and reduced power.
FAQ 2: Is it illegal to dump gasoline down the drain or in the yard?
Yes, it is illegal and environmentally irresponsible to dump gasoline down the drain, into the yard, or into storm sewers. This can contaminate soil, water sources, and pose a fire hazard.
FAQ 3: What kind of container should I use to store old gasoline for disposal?
Use a red, UL-approved gasoline container specifically designed for storing flammable liquids. Ensure the container is tightly sealed and clearly labeled as “Old Gasoline.”
FAQ 4: Can I mix old gasoline with used motor oil for disposal?
No. Mixing gasoline with used motor oil creates a more complex and hazardous waste stream, making it more difficult and costly to dispose of properly. Keep them separate.
FAQ 5: How long does gasoline typically last before going bad?
Gasoline can start to degrade within 3 to 6 months, depending on storage conditions. High temperatures and exposure to air accelerate the degradation process.
FAQ 6: Will fuel stabilizer prevent gasoline from going bad?
Fuel stabilizer can significantly extend the lifespan of gasoline, but it will not prevent it from eventually going bad. It’s most effective when added to fresh gasoline that will be stored for an extended period.
FAQ 7: Is it safe to store old gasoline in my garage?
Storing old gasoline in your garage is not recommended due to the fire hazard. If you must store it, keep it in a well-ventilated area away from heat sources, sparks, and flames. Use an approved gasoline container and store it away from living spaces.
FAQ 8: What should I do if I spill gasoline while transferring it for disposal?
Immediately contain the spill with absorbent materials like kitty litter or sand. Contact your local fire department or hazardous materials team if the spill is large or poses a threat to the environment. Never use water to clean up a gasoline spill.
FAQ 9: Can I dispose of old gasoline at an auto parts store?
Some auto parts stores may accept used motor oil for recycling, but they typically do not accept gasoline due to its flammable nature. Check with your local stores for their specific policies.
FAQ 10: Are there any tax incentives for disposing of hazardous waste responsibly?
Some jurisdictions may offer tax incentives or rebates for responsible disposal of hazardous waste, including old gasoline. Check with your local government or environmental protection agency for information on available programs.
FAQ 11: What happens to the gasoline once it’s taken to a hazardous waste facility?
Hazardous waste facilities typically process old gasoline through incineration or blending processes. Incineration destroys the gasoline through high-temperature combustion, while blending processes mix the gasoline with other fuels for use in industrial applications.
FAQ 12: What are the environmental consequences of improperly disposing of old gasoline?
Improper disposal of old gasoline can lead to soil and water contamination, harming plant and animal life. It also contributes to air pollution and can pose a serious fire hazard. Responsible disposal protects the environment and public health.
