It is illegal to discard used motor oil or transmission fluid in the trash, on the ground, or into sewers. Used oil and oil filters can contain toxic substances that can harm local waterways. The oil taken to a collection center can be recycled into re-refined lubricating oils that meet the same standards as virgin motor oil, or can be reprocessed for use in furnaces or power plants.
Service stations that change oil must accept up to five gallons of used motor oil (including transmission fluid) per day, per person, at no charge. Some also accept motor oil filters. This practice is regulated by the NY State Department of Environmental Conservation.
Check the owner’s manual for your car for guidance on how often to change oil. Change your oil at the interval recommended, and not before.
Maintain your vehicle properly to avoid fluid leaks.
