Downloaded from www.Manualslib.com manuals search engine When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 4 miles (6 km).
It’s below freezing outside and most trips are less than 10 miles (I 6 km).
0 The engine is at low speed most of the time (as in door-to-door
delivery, or
in stop-and-go traffic).
You tow a trailer often.
0 Most trips are through dusty places.
0 The vehicle is frequently operated off-road.
If any one of these is true for your vehicle, then you need to change your oil
andfilter 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.
Four-wheel Drive Remote Oil Filter
If your vehicle has four-wheel drive, you will have a remote oil filter
located under the hood. It is mounted to the front left inner fender, behind
the headlights.
Engine Coolant Heater (Engine Block Heater)
An engine coolant heater can be a big help if you have to park outside in
very cold weather, 0°F (-18°C) or colder. If your vehicle has this option,
see “Engine Coolant Heater
” in the Index.
What to Do with Used Oil
Did you know that used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer? 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. (See
the manufacturer’s warnings about the use
and disposal of oil products.)
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 putting it in the trash, 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.
