Used automotive fluids such as engine oil, transmission oil, antifreeze, and brake fluid are considered hazardous waste and should be disposed of properly. Before draining any fluids, consult with local authorities; in many areas, waste oil, etc.is accepted as part of recycling programs. Many service stations and auto parts stores accept waste fluid for recycling. Be forewarned that many of these collection sights will not accept mixed fluids (such as oil and antifreeze). All waste fluids should be stored in separate containers.
