RE-REFINING VERSUS RECYCLING
Re-refining is a process that removes all impurities, both soluble and insoluble, and returns the oil to a quality suitable for automobiles. Re-refined oil has quality that is equal to or better than some virgin base oils. In fact, when re-refining using hydrotreating process, the product base oil can meet API group II specifications.
The term “recycling” used oil generally means to take used motor oil and use it for a different purpose, most commonly to be burnt as fuel. “recycling oil” or “reconditioning oil” is most commonly referring to using commercial filtration systems to remove insoluble impurities. This method does not remove any of the soluble contaminants resulting in oil that has very limited uses, only good for one-time use. Reconditioned oil is not suitable for use in automobiles.
