What to Do with Used Oil Did you lmow that used engine oil contains certain elements that may be unhealthy for your skin andcould even cause cancer? Don't let used oil stay on your skin for very long. Clean your skin and nails with soap andwater, or a good hand cleaner. Wash or properly throw away clothing or rags containing used engine oil. (See the manufacturer's warnings about the use and disposal of oil products.) Used oil can be a real threat to the environment. If you change your own oil, be sure todrain all free-flowing oil from the filter before disposal. Don't ever dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help. /i\ CAUTION: 0pemtin.gthe c n g i with the air ~ cleaner off can calfst2 you 0.f others to be burned.
