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.
The oil we find underground is called crude oil. Crude oil is a mixture of hydrocarbons-from almost solid to gaseous. These were produced when tiny plants and animals decayed under layers of sand and mud millions of years ago.Crude oil has to be changed before it can be used for anything.This happens in an oil refinery.rude oil is a mixture of hydrocarbons-from almost solid to gaseous.
