What Kind of Oil to Use
Oils recommended for your vehicle can be identified by
looking for the “Starburst” symbol.
This symbol

oil has been certified by the American
Petroleum Institute (MI). Do not use any oil which
does not
carry this Starburst symbol.

If you change your own oil,
be sure
you use oil that has
the Starburst symbol
on the
front of the oil container.
If you
have your oil changed for you, be sure the oil put
into your engine is American Petroleum Institute
certified
for gasoline engines.
You should also use the proper viscosity oil for your
vehicle,
as shown in the following chart:

Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving
in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrler on top of
your vehicle.
The vehicle is used for delivery service, police, taxi

Driving under these conditions causes engine oil to
break down sooner. 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
occurs first.
If none of them

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. Lf
you have a problem properly disposing of your used oil,
ask your dealer, a service station or
a local recycling
center for help.

Operating the engine with the air cleaner off can
cause you or others to
be burned. The air cleaner
not only cleans the air, it stops flame if the,engine

damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.
Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
0 In heavy city traffic where the outside temperature

0 When doing
frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If
YOU do not use your vehicle under any of these
conditions, the fluid
and filter do not require changing.
See “Scheduled Maintenance Services” in the Index.

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use. See “Recommended
Fluids
and Lubricants” in the Index.
If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross-hatched area on
the dipstick.
