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.

NO-antifreeze

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.

What Happens to Recycled Motor Oil

Used motor oil can be cleaned and recycled, which helps keep it out of waterways. Recycled oil is then used to make heating oil, asphalt and other petroleum-based products; it is usually not recycled and resold as motor oil.
