One litre of used oil can contaminate one million litres of water. As a result, oil recycling plays a significant part in tackling pollution and promoting responsible industry by processing waste liquid and reducing the need to produce petroleum. Recycled oil performs as well as virgin oil and it would take 42 litres of crude oil to produce the equivalent of one litre of recycled waste oil.
Automotive and Industrial oil is never used up, it simply gets dirty. In normal use, water, sediment and other impurities are absorbed, affecting the oil's performance and eventually he oil must be replaced. However, waste oil can be processed to produce clean oil.
