SN 500 RE Refined Base Oil

The re-refined oil has gone through the same refining process as crude oil does to become virgin oil, it is as good of quality as virgin oil (and sometimes better). In addition, re-refined oil is more environmentally friendly than virgin oil. Re-refining waste oil uses 3x less energy than it takes to refine crude oil into virgin oil. Some oils, such as motor oils, can be refined many times over for maximum savings.
