1998 Oldsmobile Achieva oil temperature

! To Use the Engine Coolant Heater
1. Turn off the engine.
1 2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 11 0-volt AC oatlet.
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord
into a properly grounded three-prong
110-volt
AC outlet. If the cord won’t reach, use
a heavy-duty three-prong extension cord rated
for
at least 15 amps.

How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list.everyhng here, we ask that you contact
your retailer in the area where you’ll be parking your
vehicle. The retailer can give you the best advice for
that particular area.

Your automatic transaxle
has a

the seats.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it away
from moving engine parts.
If you don’t, it could
be damaged.
PARK (P): This locks your front wheels. It’s the best
position
to use when you start your engine because your
vehicle can’t move easily.

What Kind of Engine Oil to Use
Oils recommended for your vehicle can be identified
by looking for the “Starburst” symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute (API).
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:
RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS
FOR BEST FUEL ECONOMY AND COLD STARTING, SELECT THE LOWEST
SAE VISCOSITY GRADE OIL
FOR THE EXPECTED TEMPERATURE RANGE.

- SAE I 1OW-30
LOOK #?34k
FOR MIS
SYMBOL
DO NOT USE SAE 2OW-50 OR ANY OTHER
GRADE OIL NOT RECOMMENDED
6-15

As shown in the chart, SAE 5W-30 is best for your
vehicle. However, you can use
SAE 1 OW-30 if it's going
to be
0" F (- 18 " C) or above. These numbers on an oil
container show its viscosity, or thickness.
Do not use
other viscosity oils, such as
SAE 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
"Starburst" symbol. Failure to use the
recommended oil can result in engine damage not
covered by your warranty.
GM Goodwrench@ oil meets all the requirements for
your vehicle.
If you are in an area where the temperature falls
below
-20°F (-29"C), consider using either an
SAE 5W-30 synthetic oil or an SAE OW-30 oil. Both
will provide easier cold starting and better protection
for your engine at extremely low temperatures.
Engine Oil Additives
Don't add anything to your oil. Your retailer is ready to
advise if you think something should be added.
When to Change Engine Oil
If any one of these is true for you, use the short triplcity
maintenance schedule:
e
0
0
e
e
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 carrier on top of
your vehicle.
The vehicle
is used for delivery service, police, taxi
or other commercial application.
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.
6-16

Refer to the Maintenance Schedule to determine when to
replace the air filter.
See “Scheduled Maintenance Services” in the Index.
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
backfires.
If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the air cleaner off.
I NOTICE:
If the air cleaner is off, a backfire can cause a
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
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
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.
6-18

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.
1. Pull out the dipstick.
2. Using a long-neck hnnel, add enough fluid at the
dipstick hole to bring
it to the proper level.
3. After adding fluid, recheck the fluid level as
described under “How to Check.”
4. When the correct fluid level is obtained, push
the dipstick back in all the way.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant.
This coolant is designed
to remain in your vehicle for 5 years or
150,000 miles
(240 000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.

Maintenance Schedule
I Short TripKity Definition 1
Follow the Short Trip/City Maintenance Schedule if any
one of these conditions
is true for your vehicle:
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 carrier on top of
your vehicle. (With some models, you should never
tow
a trailer. See “Towing a Trailer” in the Index.)
If the vehicle is used for delivery service, police, taxi
or other commercial application.
One
of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down sooner:
Short Trip/City Intervals
Every 3,000 Miles (5 000 km): Engine Oil and Filter
Every 6,000 Miles (10 000 km): Chassis Lubrication
Every 15,000 Miles (25 000 km): Air Cleaner Filter
Inspection, if driving in dusty conditions.
Every 30,000 Miles (50 000 km): Air Cleaner Filter
