Re-refined oil is used motor oil that undergoes an extensive re-refining process to remove contaminants to produce good-as-new base oil. The base oil is then sold to blenders who add additive packages to produce high quality lubricants such as motor oil transmission fluid that is virtually no different from lubricating oil that is derived from crude oil.

There is no compromise in the quality of re-refined oil. Re-refined oil products are subject to the same stringent refining, compounding, and performance stands applied to virgin-oil products. American Petroleum Institute (API) licensed re-refined oils must pass the same cold-start, pumpability, rust- corrosion, engine-wear and high-temperature viscosity tests that virgin oils do. The API and American Automobile Manufactures Association (AAMA) have developed the Engine Oil Licensing Certification System (EOLCS) to ensure all engine oils consistently meet performance specifications.

Re-refined motor oil is endorsed by several car manufactures including Mercedes Benz, Ford, and General Motors. Unlike some other recycled materials, oil does not break down when re-refined; used oil is cleaned of impurities and ready for another round of high performance service. Re- refined oil must undergo the same comprehensive testing and meet the same quality standards as crude-based lubricants in order to receive certification by the API.
