Used motor oil which has impurities and dirt is fed right into a centrifuge. The centrifuge carries a rotor that spins an incredibly high RPM (revolutions each minute) and it pushes the impurities to the wall in the container that houses the rotor.

Appropriate extraction methods are used to ensure that impurities along with the clean motor oil are properly separated, and the oil is able to be re-used. These filtering systems can also be suitable for use with small-scale biofuel setups to get rid of any impurities.
