Used Oil Can Be Recycled in the Following Ways

 Reconditioned on site, which involves removing impurities from the used oil and using it again. While this form of recycling might not restore the oil to its original condition, it does prolong its life.

Inserted into a oil recycling plant , which involves introducing used oil as a feedstock into either the front end of the process or the coker to produce gasoline and coke.
Re-refined, which involves treating used oil to remove impurities so that it can be used as a base stock for new lubricating oil. Re-refining prolongs the life of the oil resource indefinitely. This form of recycling is the preferred option because it closes the recycling loop by reusing the oil to make the same product that it was when it started out, and therefore uses less energy and less virgin oil.
Processed and burned for energy recovery, which involves removing water and particulates so that used oil can be burned as fuel to generate heat or to power industrial operations. This form of recycling is not as preferable as methods that reuse the material because it only enables the oil to be reused once. Nonetheless, valuable energy is provided (about the same as provided by normal heating oil).

Previous: 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......

Next: Why Recycle Oil?

 More than 3 billion quarts of oil are consumed by U.S. cars and trucks annually.By reclaiming that oil after use, it lessens our dependence on foreign oil, and assures that used oil doesn't damage the environment. Disposing of used oil properly helps protect our local ecosystems by keeping used o......
