Here’s some scary news: It takes only one pint of oil to produce a one-acre slick on surface water.
To dispose of used motor oil safely, carefully pour the oil into a suitable container. You can buy specially designed one at an automotive store or just use a clean, preferably clear, container with a closeable lid. (Don’t use containers that previously contained household chemicals such as bleach.) Plastic milk jugs with screw caps work well.
Filled containers should be taken to a collection center for proper recycling. To find out where one is, contact your city or town office or call 1-888-TAKEOIL (825-3645).
