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
(-18°C) or above. 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.
If you cannot find oils with the new
“starburst” symbol on the front of the
container, you should look for and use
oils containing the following three things:
SH or SG
“SH’ or “SG’ must be on the oil container,
either by itself or combined with other
quality designations, such as “SHKD,”
“SH,SG,CD,” “SG/CD,” etc. These
letters show American Petroleum
Institute (API) levels of quality.
SAE 1OW-30 (3800 engine)
SAE 5W-30 (3100 engine)
Energy Conserving I1
Oils with these words on the
container will help you save fuel.
These three things are usually included
in a doughnut shaped logo (symbol) on
most containers.
If you cannot find oils
with the “starburst” symbol,
you should
look for oils with the doughnut shaped
symbol, containing the three things
noted above. If
you use oils that do not have
either the “starburst” symbol or an
API SH or
SG designation, you can
cause engine damage not covered
by your warranty.
GM Goodwrench@ oil (in Canada, GM
Engine Oil) meets all the requirements
for your vehicle.
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 ltm).
It’s below freezing outside and most
trips are less than
10 miles (16 ltm).
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 ltm) or 3
months - whichever comes first.
If none
of them is true, change the oil
every
7,500 miles (12 500 ltm) 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. 193

Junction Block Fuse
You'll find this fuse under the hood in
the
ABS junction block, located next to

To open the junction block, press in on
both sides of the cover.

Injector 3365 Fuse
(3800 V6 ENGINE ONLY)
This 20-amp fuse is located underhood,
on a bracket just behind the passenger
side headlight. It is mounted on the face
of the bracket in the position closest to
the passenger side of the vehicle. The
fuse services the injectors, fuel pump,
oil pressure sender and fuel pump
switch.
To access the fuse, pry back the latch
with a screwdriver, then pull down on
the base
of the unit. If you need to
replace the fuse, be sure to use a 20-
amp fuse.
Push the base of the unit firmly up into
the cover until the latch snaps into the
locked position.
Headlight Wiring
The headlight wiring is protected by a
circuit breaker in the light switch. An
electrical overload will cause the lights
to go on and off: or
in some cases to
remain off. If this happens, have your
headlight system checked right away.
Windshield Wipers
The windshield wiper motor is
protected by a circuit breaker and a
fuse.
If the motor overheats due to
heavy snow, etc., the wiper will stop
until the motor cools.
If the overload is
caused by some electrical problem, have
it fixed.
Power Windows and Other Power
Options
Circuit breakers in the circuit
breakerhelay panel protect the power
windows and other power accessories.
When the current load is too heavy, the
circuit breaker opens and closes,
protecting the circuit until the problem
is fixed.
