Used Motor Oil Certified Collection Center Drop-off Location Finder
California Certified Used Oil Collection Centers will take used motor oil from the public and will pay you 40¢ a gallon. Most centers will take up to 5 gallons at a time.
Certified center managers will not accept used motor oil that has been contaminated with other fluids such as antifreeze, solvents, gasoline, or water. Bring contaminated motor oil to a Household Hazardous Waste Facility. See the Used Motor Oil Fact Sheet for more information.
