Don't Dump in Trash or Down Drain

Used motor oil is a major contaminant of waterways, so never dump down the drain or in the trash. Filters also leak toxic materials into waterways, which are slow to break down in the environment.


Never Mix with Other Chemicals

Service stations will not accept motor oil that has been contaminated with other products like antifreeze. Don’t mix your motor oil with anything else.

Alternative Ways to Recycle
