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.
