IMPORTANT: Used motor oil may cause skin cancer if repeatedly
left in contact with the skin for prolonged periods. Although this
is unlikely unless you handle used oil on a daily basis, it is still
advisable to thoroughly wash your hands with soap and water as
soon as possible after handling used oil.
NOTE: Please dispose of used motor oil in a manner that is
compatible with the environment. We suggest you take it in a
sealed container to your local service station for reclamation. Do
not throw it in the trash or pour it on the ground.
