Engine Block Heater Option: A n engine block heater can be a big help if
you have to park outside in very cold weather, 0°F (-18OC) or colder. If
your vehicle has this option, see "Engine Block Heater" in the Index.

CAUTION:
Used engine oil contains things that have caused skin cancer in
laboratory animals. Don't let used oil stay on your skin for very
long. Clean your skin and nails with soap and water, or a good
hand cleaner. Wash or properly throw away clothing or rags
containing used engine oil.
Used oil can be a real threat to the environment. If you change your own
oil, be sure to drain all free-flowing oil from the filter before disposal.

Don't ever dispose of oil by 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.
