Downloaded from www.Manualslib.com manuals search engine When to Change Engine Oil:
See if any one of these is true for you:
0 Most trips are less than 4 miles
(6 km).
It’s below freezing outside and most
trips are less than
10 miles (1 6 km).
The engine is at low speed most of the
time (as in door-to-door delivery, or
in
stop-and-go traffic).
0 You tow a trailer often.
@ Most trips are through dusty places.
If any one
of these is true for your
vehiclej
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 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 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.

Drain, flush and refill the system
with new or approved recycled
coolant conforming to

Index. This provides proper
freeze and boil protection,
corrosion inhibitor level and
maintains proper engine

are cracked, swollen or deterior-
ated. Tighten screw-type hose
clamps. Clean the outside
