Used fluids such as engine oil, transaxle fluid, antifreeze and brake fluid are hazardous wastes and must be disposed of properly. Before draining any fluids, check local laws concerning the disposal of hazardous wastes. In many areas, waste oils, etc. are being accepted as a part of recycling programs. A number of service stations and auto parts stores are also accepting waste fluids for recycling.
Be sure of the recycling center's policies before draining any fluids, as many will not accept different fluids that have been mixed together, such as oil and antifreeze.
