139 Starting and driving
Recommended fuel:The engine in your Saab 9-3 is designed to
operate on unleaded gasoline that has an
octane rating of:
AON 90 (minimum 87) for 185 hp
engines.
AON 93 (minimum 87) for 205 hp engines
and Viggen.
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. In many
cases, you may not be able to determine the
exact type or percentage by volume of fuel
additive in the gasoline you purchase for
your car.
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-
NOTE 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.

162 Starting and drivingTowing a car with automatic
transmission The following rules must be observed if a
car with automatic transmission is to be
towed.
The gear selector must be in the N position.
Switch hazard lights on.
Drive carefully and do not exceed the
speed limit for vehicles in tow.
Always try to keep the towrope taut by
gently applying the brake as necessary.
This will avoid the towrope being jerked vio-
lently.1 Selector lever in position N.
2 Raise the oil level in the gearbox above
normal by 2 extra quarts. Use oil of type
Texaco Texamatic Dexron III.
3 The local regulations on towing speeds
must be followed.
The highest permissible towing speed is
30 mph (50 km/h), unless the legal limit
is lower. The longest permissible towing
distance is 25-30 miles (40-50 km). If the
car has to be transported farther than
that, summon a tow truck. A flat bed tow
truck is the preferred method to tow.
4 When the car is being returned to ser-
vice, check the gearbox oil, and reduce
it to the prescribed amount if necessary.
The engine cannot be started by towing or
pushing the car. In emergency, the engine
can be started as described in the section
”Jump starting”.
Jump startingIf your battery has run down, you may want
to use another vehicle and some jumper
cables to start your Saab. Follow the steps
below to do it safely.
NOTEThe car must be towed front first.
If the car is to be towed with the front
wheels off the ground, make sure the
parking brake is off, as this acts on the
rear wheels.
WARNING
Batteries can cause injury. They can be
dangerous because:
They contain acid that can burn you.
They contain gas that can explode or
ignite.
They contain enough electricity to
injure you.
If you do not follow these steps exactly,
some or all of these things can hurt you.

Oil grade: 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 ex-
ample 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
gasoline 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 normally encompass semi and fully-synthetic oils.
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.
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 A2/B2 or A3/B3.
These oils contain the additives required for the engine to
function well. We advise against the use of further addi-
tives.
