How to Dispose of Used Motor Oil and Antifreeze

Just one gallon of used motor oil can contaminate one million gallons of drinking water. It is a serious federal violation under the Clean Water Act to dump motor oil on the ground, down storm sewers, or in household trash carts.

Key Takeaway

Federal regulations require most retail auto parts chains that sell motor oil to accept used motor oil back from consumers free of charge. Always verify your local municipal hauler requirements before placing large items at the curb.

Step-by-Step Instructions

1
Drain oil into a clean, dedicated drain pan

Ensure the pan is clean and free of water, antifreeze, or dirt before collecting oil from your engine.

2
Transfer into a clean, sealable plastic container

Use clean plastic jugs with tight screw caps, such as original oil bottles. Never use milk jugs, which degrade quickly and leak.

3
Keep motor oil separate from other automotive fluids

Never mix motor oil with brake fluid, antifreeze, gasoline, or solvents, as contaminated oil cannot be recycled.

4
Return to an auto parts store or quick lube shop for free recycling

Retailers like AutoZone, Advance Auto Parts, and O’Reilly Auto Parts accept up to 5 gallons of used motor oil per visit free of charge.

⚠️ Important Rules to Avoid Fines & Hazards

  • Never pour motor oil into street storm drains, septic tanks, or onto the ground.
  • Used oil filters retain up to one pint of motor oil and must also be drained hot for 12 to 24 hours before recycling.
  • Antifreeze (ethylene glycol) has a sweet odor attractive to pets and children but is lethal if consumed; dispose of antifreeze only at certified county hazardous waste collection centers.
