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.
