The regulations about the disposal and recycling of auto chemicals purchased via Instacart can vary by city and state, so you should check on the laws in your area. In many locations, you can recycle used oil by draining it into a catch container. Place an oil pan underneath the container to prevent spills. If you need to drain your vehicle's Antifreeze to make a repair, you can usually put it back afterward. Just keep it in a catch container, as you would with oil, until you're finished with the repair. Before disposal or recycling, never mix auto chemicals that you buy via Instacart together. They could react with each other, so you should keep each type of fluid in its own container. You can call your local waste management company to determine what disposal or recycling options are available in your area.
