When doing a DIY oil change, your first question is, what do I do with the old motor oil? Well, instead of having containers of dirty oil lying around your garage, find out how you can dispose of used motor oil correctly.
Used motor oil is one of the most recyclable substances in the consumer waste stream. Doing it right is free, takes a few minutes, is available almost everywhere in the country.
Quick 4-step summary: (1) Drain into a clean, leak-proof container. (2) Cap and label the container. (3) Store away from heat, ignition sources, and stormwater drains. (4) Drop off at a participating auto-parts store, oil-change shop, or municipal household-hazardous-waste facility. Most accept used oil free of charge.
Why Used Oil Is Considered Hazardous Waste
During use, motor oil picks up heavy metals (lead, zinc, cadmium), combustion by-products, and chlorinated compounds. Once contaminated, it cannot be poured into the trash, the ground, or any drain.
Federal law requires used oil to be either (a) recycled into re-refined base oil, (b) reprocessed into industrial fuel, or (c) disposed of through a permitted hazardous-waste facility.
Collect, Store, Transport
With an easy step-by-step process for disposing of used oil, you never have to hope you did it right.
What to Put Used Oil In
- Use: a clean, leak-proof container with a secure cap. The empty oil jug that your fresh oil came in is ideal.
- Avoid: milk jugs, food containers, anything previously used for chemicals, antifreeze, paint, or solvents. Cross-contamination disqualifies the oil from recycling.
- Never: mix used oil with antifreeze, gasoline, brake fluid, or any other automotive fluid. Mixed fluids are treated as hazardous waste at the high end of the cost scale.
How to Store Motor Oil Safely at Home
Keep the sealed container indoors or in a covered area, away from direct sunlight, heat sources, and any ignition source (water heater, furnace, electrical equipment). Store it on a non-porous surface or in a secondary catch tray in case of leaks. Do not stack containers.
How to Transport Motor Oil without Spilling
Place the container upright in a plastic bin or cardboard box in the trunk or bed of your vehicle. Drive directly to the drop-off location. If a spill occurs in transit, absorbent material (cat litter, oil-dry, sawdust) will contain it; never wash spilled oil into a storm drain.
Free Drop-Off Locations for Used Motor Oil
Because used oil is recyclable, many places will collect your used motor oil for free. Choose a convenient location, and cross it off your to-do list.
National Auto Parts Chains
AutoZone, O'Reilly Auto Parts, Advance Auto Parts, NAPA, and Walmart Auto Care Centers accept used motor oil free of charge at most locations. Call ahead to confirm since daily and per-visit limits vary by store.
Service Centers
Many full-service oil-change shops accept used oil from DIYers free of charge. Local independent garages often do as well.
Municipal Household Hazardous Waste Facilities
Every U.S. county operates an HHW (Household Hazardous Waste) facility or scheduled collection day. Contact your local solid-waste authority for hours and acceptance criteria. Most accept used motor oil from residents free of charge with a quick search of your county's environmental services site.
Can You Dispose of Used Oil Filters the Same Way?
Yes, most used-oil drop-off locations also accept used oil filters. Drain the filter into your used-oil container for at least 12 hours before drop-off (filters retain a significant amount of oil). Some jurisdictions require crushed filters; most do not.
Browse the Valvoline oil-filter selection for replacement filters.
Is Used Motor Oil Flammable?
Used motor oil has a flash point above 300°F, high enough that it's classified as a combustible (not flammable) liquid by the National Fire Protection Association. It will burn under sustained heat or in the presence of an open flame, but it does not ignite at room temperature like gasoline. Store away from heat sources and never near a water heater, furnace, or open electrical equipment.
How to Clean Up Motor Oil Spills
Even if the oil is soaked up in rags and clean-up materials, you still need to be careful about how you dispose of those items. First, clean up. Then, dispose of the items correctly.
On Clothes
Treat the stain quickly. Apply liquid dish soap directly to the stain, work it in with your fingers, let it sit 10 minutes, then wash on the hottest setting the fabric allows. For stubborn stains, repeat or pre-treat with a citrus-based degreaser.
Air-dry the clothing item if you are unsure whether the stain treatment worked. Heat from a dryer can set residual oil into the fibers permanently.
On Concrete
Cover the spill with cat litter, sawdust, or commercial oil-dry. Let it sit 24 hours, then sweep up and dispose of the absorbent in a sealed bag (most municipalities allow this in regular trash if it's a small amount and the absorbent is fully saturated).
For lingering stains, scrub with a stiff brush, dish soap, and warm water; for set-in stains, use a poultice (baking soda paste or a commercial concrete degreaser).
On the Garage Floor
Same procedure as concrete. For prevention, place a drip mat or large piece of cardboard under the engine before changes; the absorbent catches inevitable drips and doubles as the workplace surface for the new filter and drain plug.
Frequently Asked Questions
Where can I dispose of motor oil for free near me?
AutoZone, O'Reilly, Advance Auto Parts, NAPA, Walmart Auto Care, and some independent oil-change shops accept used oil free of charge. Call the nearest location to confirm daily and per-visit limits before you make the trip.
Can I throw away used motor oil?
No, do not put used motor oil in the trash. Disposing of it in regular trash is illegal under federal law and in every state. Used oil must be recycled or processed at a permitted facility.
Can I burn used motor oil?
Only burn used motor oil in EPA-permitted used-oil heaters or industrial burners. Burning used oil in an open fire can release heavy metals into the air and is illegal in most jurisdictions.
How long can I store used oil before recycling it?
You can store used motor oil indefinitely if stored properly (in a sealed container, away from heat and ignition sources). There is no expiration on the recycling stream. Used oil retains all of its energy and base-stock value for years.
Can I mix used oil from multiple cars in one container?
Yes, you can mix used oil from different cars as long as it's all engine oil. Don't mix in transmission fluid, antifreeze, brake fluid, or gear oil. Mixing different fluid types disqualifies the oil from straightforward recycling.
Does new motor oil expire in the bottle?
An unopened bottle of motor oil is generally good for 5+ years stored in stable, room-temperature conditions out of direct sunlight. Once opened, use within 12–24 months because moisture absorption and air exposure degrade the additive package. If you find an old bottle of oil that you're not going to use, it goes in the same recycling stream as used oil.
Disposing of Used Motor Oil the Right Way
Used motor oil is recyclable, so it is illegal to throw it away to be taken to the dump, as it poses a fire risk. Instead, drop it off at your local auto body shop for reuse.
Drain it cleanly, store it safely, and drop it off where it's accepted.
