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.
CAUTION: 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.
