than
10 miles (16 km).
. The engine is -at low .speed most of the time (as in
door
tp door delivery, or in stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
If -any one of these is true for your vehicle, then you
need-to change
your oil.and filter every 3,000 miles
(5 000 km) or, 3 months - whichever comes first.
If none of them is true, change the oil every 7,500 miles
(12 -500 km) or 12 months - whichever comes first.
Change the filter at the first oil change and
at every
other oil change after that.
Engine Block Heater: An engine block heater can be a
big help if-you have
to park outside in very cold
weather,
-20 * F (-29 C] or .colder. If your vehicle has
this option, see
“Engine Block Heater” in the Index.

Used oil can be a real threat to the environment. If you
change your
own oil, be sure to drain all free-flowing oil
Erom 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.
