Used oil is exactly what its name implies, any petroleum-based or synthetic that has been used. During normal use, impurities such as dirt, metal scrapings , water or chemicals, can get mixed in with the oil, so that in time, the oil no longer performs well. Eventually, this used oil must be replaced with virgin or re-refined oil to do the job correctly.

If you are one of the many people who change their own motor oil, you too need to know how to properly dispose of the used oil. Did you know that the used oil from one oil change can contaminate 1 million gallons of groundwater if dumped down a storm drain?
