oil additives SAAB 9-5 2001 Owners Manual

242 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 good advice!
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 Specifi-
cation section of this Owner’s Manual. The
use of extra additives in the oil is not neces-
sary and is not recommended, and may be
harmful to turbochargers.
More frequent oil changes are recom-
mended if your vehicle is operated under
the following conditions:
 Extensive idling
 Stop-and-go driving
 Driving in cold climates over repeated
short trips without sufficient engine
warm-up, see page 194.
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. The Warranties and
Service Record Booklet 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.

253 Specifications
Engine oilOil specification
:
We recommend the use of oils that are available from your Saab
dealer, for the regular oil changes.
These oils fulfill the most stringent requirements set by API and
ACEA classifications.
Oil for gasoline engines is classified by the API standards
(American Petroleum Institute) into the grade classes SH (since
1993) and SJ (since 1996). The SJ class fulfils more stringent
requirements and has a lower phosphorous level.
These grade classes are most often combined with the corre-
sponding classes for diesel engines. The class designations for
diesel engines begin with the letter ”C” (Commercial). For exam-
ple a grade combination suitable for both types of engine could
be API SH/CD or SJ/CF.
Under ACEA nomenclature, oils are divided into Class A for gas-
oline engines and Class B for diesel-engined passenger cars.
There is a further class for heavy diesel engines. Each class is
divided into three grades: 1, 2 and 3, where grades 2 and 3 nor-
mally encompass semi and fully-synthetic oils. The diesel class
B also has a fourth grade, B4, which encompasses tests and
regulations aimed at improving the performance of direct injec-
tion 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.
To afford Saab engines the best protection, with regard to lubri-
cation, the ability to dissolve residues and the neutralization of
combustion products, we recommend the following oil grades:
 API SH/CD/CF or SJ/CD/CF.
 ACEA A3/B3/B4.
These oils contain the additives required for the engine to
function well. We advise against the use of further addi-
tives.
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 viscosities, e.g. 10W-30,
where the 10W meets certain viscosity requirements at -4°F
(-20°C), while the 30 fulfills requirements at a temperature of
212°F (100°C).
Basic recommendations for Saab engines:
SAE 5W-30 or 5W-40.
The oil should be semi or fully synthetic and fulfil the grade
requirements for ACEA A3/B3 or API SJ.
Oils which are less viscous, such as 0W/-40/50 are becoming
more common and may be used. However, the oil must be
fully-synthetic, of a well known brand, and fulfil ACEA grade
requirements A3/B3.
This viscosity makes starting in cold weather easier.
