We all know that we are supposed to change the oil in our cars on a regular basis, but other than natural or synthetic, most people do not usually think much about what oil goes in or comes out. Re-refined or re-processed oil is engine lubricant that is what it sounds like — used oil that has been re-refined for reuse. How is re-refined oil made and is it safe?

The exact process of re-refining oil
Oil from petroleum doesn't wear out. Instead, as it circulates through an engine, it gets dirty. The additives that are in the oil do wear out, but the oil itself doesn’t. Used motor oil is re-refined the exact same way as crude oil. The oil is cleaned, refined and then is re-blended with additives to create a product that is comparable to lubricants created with crude oil.
Your re-manufactured oil needs to be approved
You should take precautions before using it although it is safe. Make sure the re-refined oil being used is American Petroleum Institute approved. Typically API approved oil will be required. API approved oil has also undergone stringent testing needs that make certain it does what it is intended to. Whether re-refined or not, you’ll need oil that is API approved. If you use a quick-lube service, check with them that they are using API approved oil, re-refined or not.
Benefits of re-refined oils
Your engine could be lubricated by re-refined motor oil. Used motor oil is considered a toxic waste, and is typically disposed of in a variety of ways. Re-refining oil helps create a closed-loop system, where the nonrenewable resource of oil is consistently re-used. A gallon of used motor oil creates 2.5 quarts of re-refined oil. The byproducts are used to power re-refining plants and also to create asphalt roof shingles. If all motor oil in the United States was re-refined, there would be enough recycled oil to maintain about 8 million vehicles every single year.
