2003 SAAB 9-5 gas type

159 Starting and driving
Opening the fuel filler door in an emergency,
see page 150.
Recommended fuel:The engine in your Saab 9-5 is designed to
operate on unleaded gasoline that has an
octane rating of 87 or higher. Octane rating
is determined according to the formula:
where MON is the Motor Octane Number,
and RON is the Research Octane Number.
The average of these two values is the
octane rating of the gasoline as it appears
on the pump at a retail gas station. This
value is sometimes referred to as the
"Anti-Knock Index" (AKI) or the "Average
Octane Number" (AON).
To avoid deposit formation on the fuel injec-
tors which can cause poor driveability, use
only quality gasolines that contain deter-
gents and corrosion inhibitors. Because
gasolines sold at retail gas stations vary in
their composition and quality, you should
switch to a different brand if you begin expe-
riencing driveability and/or hard starting
problems shortly after refueling your car. In
recent years, a variety of fuel additives and
alcohols or oxygenates have been blended
with gasoline. These types of gasolines may
be found in all parts of the United States and
Canada, but particularly in geographic
areas and cities that have high carbon mon-
oxide levels. Saab approves the use of such
"reformulated" gasolines in its products,
which help in reducing pollution from all
motor vehicles, provided that the following blending percentages are met by such
fuels:
 Up to 10 % ethanol by volume, with corro-
sion inhibitors.
 Up to 15 % MTBE by volume (methyl ter-
tiary butyl ether).
 Up to 5 % methanol by volume, with an
equal amount of a suitable co-solvent and
added corrosion inhibitors.
Other, less common, fuel additives used by
some gasoline dealers are also acceptable,
provided that the resultant gasoline is not
more than 2.7 % oxygen by weight.
Some Canadian and U.S. gasolines contain
an octane enhancing additive called meth-
lycyclopentadienyl manganese tricarbonyl
(MMT). If such fuel is used, your emission
control system performance may deterio-
rate and the malfunction indicator lamp on
your instrument panel may turn on. If this
occurs, return to your authorized Saab
dealer for service.
However, these blended gasolines are reg-
ulated and should never exceed these rec-
ommended blend percentages and service
station operators should know if their gaso-
lines contain detergents and oxygenates,
and have been reformulated to reduce vehi-
cle emissions. Nevertheless, if you begin to
notice a problem with the way your car starts
or runs shortly after it has been refueled, try
a different brand of gasoline.
NOTICE Fill to maximum filling capacity
 Stop filling after the first time that the
nozzle trips to shut off the flow of fuel.
 Filling capacity can differ between
different fuel stations and outside
temperature. Fuel tank volume when
nozzle trips to shut off, may vary by
0.5 gal. (2 liters).
 Do not fill fuel all the way up the filler
pipe. The gasoline must be allowed
room for expansion especially during
hot weather.

161 Starting and driving
Be sure the posted octane is at least 87. If
the octane is less than 87, you may get a
heavy knocking noise when you drive. If it’s
bad enough, it can damage your engine. If
you’re using fuel rated at 87 octane or
higher and you hear heavy knocking, your
engine needs service. But don’t worry if you
hear a little pinging noise when you’re accel-
erating or driving up a hill. That’s normal,
and you don’t have to buy a higher octane
fuel to get rid of pinging. It’s the heavy, con-
stant knock that means you have a problem.
If your vehicle is certified to meet California
Emission Standards (indicated on the
underhood emission control label), it is
designed to operate on fuels that meet Cal-
ifornia specifications. If such fuels are not
available in states adopting California emis-
sions standards, your vehicle will operate
satisfactorily on fuels meeting federal spec-
ifications, but emission control system per-
formance may be affected. The ”Engine
malfunction (CHECK ENGINE)” indicator
on your main instrument panel may turn on
and/or your vehicle may fail a smog-check
test. See ”Engine malfunction (CHECK
ENGINE)” indicator on page 59. If this
occurs, return to your authorized Saab
dealer for diagnosis to determine the cause
of failure. In the event it is determined that
the cause of the condition is the type of fuels
used, repairs may not be covered by your
warranty. Some gasolines that are not reformulated
for low emissions may contain an
octane-enhancing additive called methylcy-
clopentadienyl manganese tricarbonyl
(MMT); ask your service station operator
whether or not the fuel contains MMT. Saab
Automobile AB does not recommend the
use of such gasolines. If fuels containing
MMT are used, spark plug life may be
reduced and your emission control system
performance may be affected. The malfunc-
tion indicator lamp on your instrument panel
may turn on. If this occurs, return to your
authorized Saab dealer for service.
Engine Break-In PeriodPistons, bores and bearings need time to
obtain uniform, wear-resistant surfaces.
If a new engine is driven too hard, this grad-
ual process of bedding-in will not be possi-
ble and the life of the engine will be short-
ened.
During the first 1,200 miles (2,000 km), do
not exceed 5,000 rpm.
In addition, refrain from driving the car at full
throttle, other than for brief instances,
during the first 1,800 miles (3,000 km). Wearing in new brake padsNew brake pads take time to bed in, about
90 miles (150 km) if the car is driven largely
under stop-and-go conditions or about
300 miles (500 km) of highway driving.
To extend the useful life of the pads, avoid
hard braking as much as possible during
this period.

Engine oilOil recommendation:

We recommend the use of Saab or Mobil oils, available from
your Saab dealer, for regular oil changes. These oils fulfil
Saab’s requirements as wells as the most stringent require-
ments 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 require-
ments for ACEA A3/B3, API SJ or higher. In addition to API and
ACEA the ILSAC GF-3 specification is approved for use in appli-
cable 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.Oil specification.
Oil for gasoline engines is classified by the API (American Petro-
leum Institute) and ACEA (European Automobile Manufacturers
Associations) standards.
API classifies engine oil into grade classes SH (since 1993) and
SJ (since 1996). The SJ class fulfils more stringent requirements
and has lower phosphorous level. A new grade API SL, intro-
duced 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
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 die-
sel 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.
