2002 SAAB 9-3 oil viscosity

230 Maintenance and owner assistanceMaintenance scheduleThe Maintenance Schedule prescribes a
service program to the purchaser/operator
of a Saab that is reasonable and necessary
to ensure the proper emission control sys-
tems function, safety and reliability of the
Saab automobile in normal use. Additional
maintenance is recommended for specific
components when the car is operated under
certain severe conditions. Proper mainte-
nance is always a good practice!
Authorized Saab dealers are equipped and
trained to meet your Saab’s service needs.
They regularly receive up-to-date Saab ser-
vice manuals and parts and technical ser-
vice bulletins from Saab and are able,
through their franchise agreement, to attend
Saab service schools, obtain Saab special
tools and technical assistance and pur-
chase original equipment service and
replacement parts.
Today’s complex automobiles should only
be entrusted to the most knowledgeable
service professionals. A Saab dealer is your
best choice.
Service intervalsThe maintenance schedule is comprised of
a Check -up 30 days after retail delivery, fol-
lowed by services at every 10,000 miles
(16,000 km) thereafter (10,000, 20,000,
30,000 miles/16,000 32,000, 48,000 km
etc.).
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 (fre-
quent 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.
NOTEThe Check-up will be done by your Saab
dealer at no charge and should be done
as close as possible to the scheduled 30
days.

Oil recommendation: We recommend the use of oils that are available from your
Saab dealer, for regular oil changes. These oils fulfill the most
stringent requirements set by API and ACEA classifications.
Basic recommendations for Saab engines
 SAE 5W-30 or 0W-30, 5W-40.
The oil should be semi or fully synthetic and fulfill grade re-
quirements for ACEA A3/B3, API SJ or higher. In addition to API
and ACEA the ILSAC GF-3 specification is approved for use in
applicable markets.
Fully synthetic oils with viscosity’s 0W-40/50 of well known
brands and fulfilling minimum ACEA A3/B3 are also recom-
mended, especially for extreme driving conditions.

238 Technical dataOil specification
Oil for gasoline engines is classified by the API (American Pe-
troleum Institute) and ACEA (European Automobile Manufac-
turers Associations) standards.
API classifies engine oil into grade classes SH (since 1993) and
SJ (since 1996). The SJ class fulfils more stringent require-
ments and has lower phosphorous level. A new grade API SL,
introduced 2001, fulfils even higher requirements.
These grade classes are most often combined with correspond-
ing classes for diesel engines. The class designations for diesel
engines begins with the letter "C" (Commercial). For example a
grade combination suitable for both types of engine could be
API SH/CD, SJ/CF or SL/CF.
Under the ACEA nomenclature, oils are divided into Class A for
gasoline engines and Class B for diesel engine passenger cars.
There is a further class for heavy diesel engines. Each class is
divided into grades: 1,2 and 3 where grades 2 and 3 normally
encompass semi- and fully synthetic oils. The diesel class also
has a fourth grade, B4, which encompasses tests and regula-
tions aimed at improving the performance of direct injection
diesel engines.
In the same way as in the API system, gasoline and diesel
engine specifications are combined for products that can be
used in both types of engine. For example, a grade designation
could be ACEA A2/B2 or ACEA A3/B3, B4.
Viscosity: The viscosity of oil is classified according to the SAE standard.
Nowadays, multigrade oils are always used in cars. The proper-
ties of these oils facilitate starting the car in cold weather but
mean that the oil is also viscous enough to coat all moving parts
under high pressures and with high outside air temperatures.
Multigrade oils are graded with two viscosity’s, e.g. 5W-30,
where 5W meets certain viscosity requirements at -4°F (-20°C),
while 30 fulfils requirements at 212°F (100°C).
