2003 SAAB 9-3 oil additives

128 Starting and drivingRefuelingOnly use fuel from a well-known oil com-
pany.
All Saab gasoline engines can be driven on
gasoline with an octane rating between
AON 87–93.
The engine management system monitors
the combustion and automatically adapts to
the fuel used.
Always use the correct grade of fuel:
unleaded AON 87–93.For optimum performance Saab recom-
mends:
2.0t engine 175 hp – AON 90.
2.0 Turbo engine 210 hp - AON 93.
Sometimes, gasoline can contain a number
of additives containing oxygen. The most
common of these are alcohol or some type
of ether. The maximum oxygen level is
restricted by national regulations.
If fuel containing a mixture of alcohol is
used, the maximum levels approved by
Saab are: 5 % by volume of methanol; or
10 % by volume of ethanol. The most
common type of ether used is MTBE
(methyl tertiary butyl ether), of which fuel
may contain a maximum of 15 % by volume.
WARNING
Gasoline fumes are highly explosive.
Therefore:
never smoke while refueling
never use gasoline for any purpose
other than as engine fuel
 gasoline is extremely flammable and
can cause severe burns. No open or
exposed flames near gasoline
 do not use a mobile phone at the same
time as refueling
NOTICE Do not overfill. Fuel should not come
right up the filler pipe as room for
expansion is needed for when the
temperature rises.
 The use of fuel with too low an octane
rating can cause serious engine
damage.

231 Maintenance and owner assistance
Engine oil and filter changesChanging the engine oil and filter is required
at every service point. Use only a Saab
approved long-life oil filter and engine oils
meeting the SAE viscosity ratings and API
service classifications stated in the “Techni-
cal data” section of this Owner’s Manual.
The use of extra additives in the oil is not
necessary and is not recommended, and
may be harmful to turbochargers.
More frequent oil changes are recom-
mended if your vehicle is operated under
any of the following conditions:
 Most trips are less than 5–10 miles (8–
16 km). This is particularly important
when outside temperatures are below
freezing.
 Most trips include extensive idling
(frequent stop-and-go traffic).
 Most trips are through dusty areas (such
as construction zones).
 If the vehicle is used for delivery service,
police, taxi or other commercial applica-
tions.
If your driving habits match this description,
have the engine oil and filter changed in-
between normal services at 5,000 mile
(8,000 km) intervals. These conditions
cause the engine oil to break down faster.
The Warranties and Service Record Book-
let has provisions to record extra oil
changes.
Service record retentionIt is the owner’s responsibility to retain ser-
vice records. If possible, you should keep
copies of all shop work orders for all service
and repairs, whenever performed. As indi-
cated in the new car and emission control
system warranties, it is important to docu-
ment that all necessary maintenance has
been done.
HOW THE SERVICE RECORD IS ORGA-
NIZED
The service record is comprised of a main-
tenance log and a separate log sheet for list-
ing any additional service and repairs.
There are five coupons at the front of the
section, three of which are for documenting
extra engine oil and filter changes, one for
extra automatic transmission fluid services
necessary for severe service conditions,
one for brake fluid changes and one for
coolant flushes. These are followed by log
sheets for all normal scheduled mainte-
nance in the order it is to be performed,
beginning with the “First Service”.HOW TO USE THE SERVICE RECORD
COUPONS
When the car is brought to a Saab dealer for
scheduled maintenance, present the War-
ranties & Service Record Booklet to the ser-
vice manager. When the technician has
completed the service, the technician will
sign the maintenance record. The person
responsible for quality assurance at the
dealership will also sign and stamp the
record with the dealer identification stamp.

Oil grade
:
We recommend the use of Saab or Mobile oils, available from
you Saab dealer, for regular oil changes.
These oils are specially developed from high-quality compo-
nents to meet the demands of extended service intervals (max.
18,000 miles (30,000 km) or 2 years). Saab and Mobil oils are
tested and approved in accordance with the GM standard for
long-life oils. Such gasoline engine oils are given the designa-
tion GM-LL-A 025. The requirements are the same for diesel
oils, though these are given the designation GM-LL-B 025.
To ensure optimum engine performance, with regard to lu-
brication, the ability to dissolve residues and the neutrali-
sation of combustion products in the oil, for a service
interval of 18,000 miles (30,000 km) or a maximum of
2 years, the engine oil used must fulfil GM-LL-A 025 (gaso-
line engines) or GM-LL-B 025 (diesel engines).
Only oil of the above grades may be used.
Oils of the above grades contain the additives required for
the engine to function well. We advise against the use of
further additives.
The gasoline engine oil is unique in that not only does it fulfil the
stringent requirements demanded by API and ACEA standards
but also meets ACEA requirements for fuel-saving properties.
