Oldsmobile Achieva 1995 Owner's Manuals

Underhood Light
Your parking lights or headlights must be on for the
underhood light
to function when you open the hood.
Engine Oil
If the CHECK OIL light on the instrument panel comes
on, it means you need to check your engine oil level
right away. For more information, see
”CHECK OIL
LIGHT” in the Index. You should check your engine oil
level regularly; this is an added reminder.
It’s a good idea
to check your engine oil every time you
get fuel.
In order to get an accurate reading, the oil must
be warm and the vehicle must be
on level ground.
Turn
off the engine and give the oil a few minutes to
drain back into the oil pan. If you don’t, the oil dipstick
might not show the actual level.
To Check Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
Checking Engine Oil
The engine oil dipstick handle is yellow. The dipstick
handle for the
2.3L L-4 is located behind the engine.
The dipstick for the 3.1L
V-6 is located in front of the
engine behind the fan.

When to Add Oil
If the oil is at or below the ADD line, then you’ll need to
add some oil. But you must use the right kind. This put
explains what kind
of oil to use. For crankcase capacity,
see “Capacities and Specifications”
in the Index.
I NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.
Just fill it enough to put the level somewhere in the
proper operating range. Push the dipstick all the way
back in when you’re through.
What Kind of Oil to Use
Oils of the proper quality for your vehicle can be
identified
by looking for the “Starburst” symbol. The
“Starburst” symbol indicates that the
oil has been
certified by the American Petroleum Institute
(API), and
is preferred for use
in your gasoline engine.
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
certificd
for gasoline engines.
You should also use the proper viscosity oil
for your
vehicle,
as shown in the following chart:

As shown in the chart, SAE 5W-30 is best for your
vehicle. However, you can use
SAE 1OW-30 if it’s going
to be 0°F (- 1 8 “C) or above. These numbers on an oil
container
show its viscosity, or thickness. Do not use
other viscosity oils, such as
SAE 20W-SO.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst” symbol. Failure
to use the proper oil
can result in engine damage not covered by your
warranty.

GM Goodwrench@ oil (in Canada, GM Engine Oil)

for your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your Oldsmobile retailer
is ready
to advise if you think something should be
added.

When to Change Engine Oil
See if any one of these is true for you:
0
0
0
0
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.
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 comes first.
If none of them is true, change
the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
comes first.
Engine Coolant Heater
An engine coolant heater can be a big help if you have
to park outside
in very cold weather, 0 OF (- 18 O 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 retailer, a service station or
a local recycling
center for help.

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. Refer to the
Maintenance Schedule to determine when to change
your fluid. See “Scheduled Maintenance Services’’ in the
Index.
How to Check
Because this operation can be a little difficult, you may
choose
to have this done at your Oldsmobile retailer
Service Department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading on the
dipstick.
NOTICE:
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to get an accurate reading if you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:
0 When outside temperatures are above 90 OF (32 O C).
At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
While pulling a trailer.
6-17

To get the right reading, the fluid should be at normal
operating temperature, which is 180°F to
200°F (82°C
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50°F
(10°C). If it's colder than
50°F (1O"C), you may have
to drive longer.

Park
your vehicle on a level place. Keep the engine
running.
With the parking brake applied, place the shift lever
in PARK
(P).
With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, position
the shift
lever in PARK
(P).
Let the engine run at idle for three to five minutes. Then,
without shutting
off the engine, follow these steps:
The automatic transaxle dipstick handle is red. Pull out
the dipstick and wipe it with
a clean rag or paper towel.
1. Push it back in all the way, wait three seconds and
then pull it back out again.
2. Check both sides of the dipstick, and read the lower
level.
The fluid level must be in the cross-hatched
area.
3. If the fluid level is in the acceptable range, push the
dipstick back
in all the way.

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 funnel, add enough fluid at the
dipstick hole to bring it
to the proper 1evel.It doesn’t
take much fluid, generally less than a pint
(0.5L).
Don’t overfill. We recommend you use only fluid
labeled DEXRON@-111, because fluid with that label
is made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON@-I11
is not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under “How to Check.”
When the correct fluid level is obtained, push the
dipstick back in all the way.
Manual Transaxle Fluid
When to Check
A good time to have it checked is when the engine oil is
changed. However, the fluid in your manual transaxle
doesn’t require changing.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at your Oldsmobile retailer
Service Department.
If you
do it yourself, be sure to follow all the
instructions here, or you could get
a false reading on
the dipstick.
NOTICE:
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall on hot engine parts
or exhaust system parts, starting a fire. Be sure to
get an accurate reading if you check your
transaxle fluid.
6-19

Check the fluid level only when your engine is off, the
vehicle
is parked on a level place and the transaxle is
cool enough for you to rest your fingers on the transaxle
case.
Then, follow these steps:
1. Flip the handle up and then pull out the dipstick and
clean
it with a rag or paper towel.
2. Push it back in all the way and remove it.
3. Check both sides of the dipstick and read the lower
level. The fluid level must be between the ADD and
FULL marks. (Note: Fluid may appear at the bottom
of the dipstick even when the fluid level is several
pints low.)
4. If the fluid level is where it should be, push the
dipstick back in all the way and flip the handle
down.
If the fluid level is low, add more fluid as
described
in the next steps.
How to Add Fluid
Here’s how to add fluid. Refer to the Maintenance
Schedule
to determine what kind of fluid to use. See
“Recommended Fluids and Lubricants’’
in the Index.
1. Remove the dipstick by flipping the handle up and
then pulling the dipstick out.
2. Add fluid at the dipstick hole.
Add only enough fluid
to bring the fluid level up to
the FULL mark
on the dipstick.
3. Push the dipstick back in all the way; then flip the
handle down to lock the dipstick
in place.
