The Town of Windsor has a used motor oil and filter drop-off facility at the Corporation Yard located at 8400 Windsor Road. This facility is open 24 hours/7 days a week and is available to all residents of Sonoma County (no business drop-off).
Place your motor oil in a sealable container. It is best to use a reusable motor oil drain container (please take your empty containers back with you). Make sure the oil is not mixed with any other fluids.
No more than 5 gallons of used motor oil and 2 filters may be dropped off at one time.
