Used Motor Oil
Whether you’re changing the oil in a car, truck, lawn mower or other household equipment, used oil needs to be collected and disposed of properly.
Hamilton County warns that dumping motor oil on the ground, putting it into storm drains or throwing it into the trash can contaminate soil, groundwater, streams and rivers.
Instead, collect the used oil in a secure container and bring it to the county HHW Center.
Maximum: 20 gallons per resident per visit.
Antifreeze & Other Automotive Fluids
The HHW Center isn’t limited to motor oil.
Hamilton County also accepts used antifreeze and other qualifying automotive wastes, making the facility useful when you’re doing your own vehicle maintenance.
Gasoline and diesel fuel are also accepted. Fuels must be in containers of 5 gallons or smaller, with a limit of 20 gallons per month.

How to Prepare Used Oil for Drop-Off
Keep used motor oil in a secure, clearly labeled container that won’t leak during transportation.
Hamilton County recommends:
- Keeping liquids upright.
- Using sturdy containers.
- Placing liquid containers inside plastic totes to protect your vehicle from spills.
- Keeping materials in their original containers when possible.
- Clearly labeling materials.
- Never mixing different chemicals or automotive fluids together.
- Avoiding trash bags or grocery bags for transporting liquids.
Materials that are leaking, spilling or otherwise unsafe may be refused.
Don’t Mix Motor Oil With Other Fluids
If you have motor oil, gasoline, antifreeze or another automotive fluid, keep each material separate.
Mixing chemicals can make them harder or more dangerous to handle. Hamilton County specifically warns residents not to pour different materials together because they can react.
Label containers when the contents aren’t obvious.
What About Oil Filters?
Don’t automatically put an oil filter into the same container as your used motor oil.
Because accepted materials and handling requirements can differ, check the county’s current materials list or call 317-776-4005, press 1 before bringing an item that isn’t clearly listed.

Local Tips
Save a sturdy container when doing an oil change. A secure, sealable container makes transporting used oil much easier.
Don’t mix your fluids. Keep motor oil, antifreeze and gasoline in separate containers.
