What Kind of Oil to Use (CONI)
SAE 1OW-30 (3800 V6 Engine)
As shown in the viscosity chart, SAE
1OW-30 is best for your vehicle.
However, you can use
SAE 5W-30 if
it's going to be colder than
60°F
(16°C) before your next oil change.
When it's very cold, below
0°F
(-18" C), you should use SAE 5W-30.
These numbers on an oil container
show its viscosity, or thickness.
Do
not use other viscosity oils such as
SAE 1OW-40 or SAE 20W-50.
For best fuel economy and cold starting,
select the
lowest SAE viscosity grade oil
for the expected temperature range. I

Engine Oil Additives
Don't add anything to your oil. Your
Oldsmobile dealer 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:
Most trips are less than 4 miles (6 km).
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).
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
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 Block Heater (omoN)
An engine block 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 the
Index under Engine Block Heater.

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 the
Index under
Scheduled Maintenance Services.
How to Check:
Because this operation can be a little
difficult, you may choose to have this
done at an Oldsmobile dealership
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.
