Today, with modern technologies, you could use it for passenger car motor oil, automatic transmission fluid, hydraulic fluid, heavy-duty motor oil. There's no difference between oils re-refined with modern technologies and refined oil from virgin crude.

There are many uses for recycled used oil. These include: Industrial burner oil, where the used oil is dewatered, fil......

Next: What are Lubricants?

 Lubricants are typically comprised of 80-90% base oil and 10-20% specialty additives that distinguish the product such as a motor oil, transmission or hydraulic fluid, or industrial process oil. Most all base oils originate from the processing of crude oil. The lubricants eventually become “spent......
