Q. How do I recycle Used Motor Oil? Filters? Other auto fluids?
A. Residents in Castro Valley can recycle their used motor oil, filters, and other automobile fluids for free!

For Single-Family Residents:
Place one-gallon screw-top containers curbside beside your collection carts on your regular collection day. You can recycle up to three (3) gallons per week of motor oil, transmission fluid, gear lube and other lubricants commonly used in cars and light trucks. Oil filters can be put in a heavyweight sealed clear plastic bag and placed curbside. Call WMAC at (510) 537-5500 to request delivery of a Used Oil jug and filter bag kit. Uncontaminated used oil and filters may be dropped off at a Collection Center (see below).

For Multi-Family Residents:
Place uncontaminated used motor oil in a leak-proof container (such as a plastic screw-top container) and place the old filter in a separate leak-proof container (such as a heavy duty sealed plastic bag or coffee tin with lid).  Drop off used motor oil and oil filters for recycling at a Certified Collection Center or Household Hazardous Waste facility (see below).  Used oil that has been contaminated with other fluids must be disposed of at a Household Hazardous Waste facility (see below).

Certified Collection Centers in Castro Valley and San Lorenzo
It’s easy to recycle your used motor oil and filters at Certified Collection Centers (CCCs)!  Depending on the CCC, many will take up to 5 gallons of oil per person per visit.  Upon request, Certified Collection Centers will reimburse you $0.40 per gallon or $0.10 per quart of motor oil you bring in.  And remember, don’t forget the filter! Filters can hold up to one quart of motor oil.
