When to Change Engine Oil:
See if any one of these is true for you:
Most trips are less than 4 miles
0 It’s below freezing outside and most
trips are less than
10 miles ( 16 km).
The engine is at low speed most of
the time (as in door-to-door delivery,
or
in stop-and-go traffic).
(6 km).
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
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 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
:ontains elements that may be unhealthy
:or your skin and could even cause
:ancer? Don’t let used oil stay on your
;kin for very long. Clean your skin and
lails with soap and water, or a good hand
:leaner. Wash or properly throw away
:lothing or rags containing used engine
il. (See the manufacturer’s warnings
ibout the use and disposal of oil
xoducts.)
Used oil can be a real threat to the
mvironment. If you change your own oil,
)e sure to drain all free-flowing oil from
:he filter before disposal. Don’t ever
jispose of oil by putting it in the trash,
2ouring 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.
