What is Re-Refined Oil? Re-refined oil is used motor oil that undergoes an extensive re-refining process to remove contaminants to produce a good-as-new base oil. This base oil is then sold to blenders who add additive packages to produce lubricants such as motor oil, transmission fluid, and grease.
Refining: Olive oil which is old, rancid, made from diseased olives, or has some other defect can be made palatable by refining. This is done by filtering, heating, charcoal, or chemical treatment to adjust acidity.
