About half of all motor oil used in cars in Chicago is replaced by car owners who change the oil themselves. Often these individuals dispose of the oil by pouring it on the ground or into the sewer, which is illegal. Because used oil does not readily dissolve in water and is slow to degrade in the environment, improper disposal of used oil pollutes our soil and water, and can damage local water treatment plants.
Used motor oil can be re-processed, re-refined and re-used. If you change your motor oil yourself, please dispose of the used oil by taking it to a nearby facility for recycling. Used motor oil can be dropped off at any Household Hazardous Waste Collection site. In addition, many auto-care businesses now accept motor oil for recycling, guaranteeing that people have a safe, legal place to take used motor oil. Visit Illinois Earth 911 for a list of businesses accepting used motor oil near you.
