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. Do not throw it in the trash or pour it on the ground.
