Oil & Oil Filters

What Makes it Hazardous?

Used oil and used oil filters may contain hazardous contaminants such as lead, magnesium, copper, zinc, and/or other heavy metals which are picked up from the engine. Used oil that is disposed of improperly can kill vegetation, harm wildlife, and pollute surface water and groundwater. Just one gallon of motor oil can pollute up to one million gallons of water and can form an oil slick nearly 8 acres in size. It is illegal to pour used oil on the ground, down a drain, sewer, or in the trash.
