2005 SAAB 9-5 fuel additives

141 Starting and driving
AdditivesTo provide cleaner air, all gasolines in the
United States are now required to contain
additives that will help prevent engine and
fuel system deposits from forming, allowing
your emission control system to work prop-
erly. You should not have to add anything to
your fuel. However, some gasolines contain
only the minimum amount of additive
required to meet U.S. Environmental Pro-
tection Agency regulations. Saab recom-
mends that you buy gasolines that are
advertised to help keep fuel injectors and
intake valves clean. If your vehicle experi-
ences problems due to dirty injectors or
valves, try a different brand of gasoline.
Gasolines containing oxygenates, such as
ethers and ethanol, and reformulated gaso-
lines may be available in your area to con-
tribute to clean air. Saab recommends that
you use these gasolines, particularly if they
comply with the specifications described
earlier.
Notice: Your vehicle was not designed
for fuel that contains methanol. Do not
use fuel containing methanol. It can cor-
rode metal parts in your fuel system and
also damage the plastic and rubber
parts. That damage would not be cove-
red under your warranty.Some gasolines that are not reformulated
for low emissions may contain an octane-
enhancing additive called methylcyclopen-
tadienyl manganese tricarbonyl (MMT); ask
the attendant where you buy gasoline
whether the fuel contains MMT. Saab does
not recommend the use of such gasolines.
Fuels containing MMT can reduce the life of
spark plugs and the performance of the
emission control system may be affected.
The malfunction indicator lamp may turn on.
If this occurs, return to your authorized Saab
dealer for service.
Fuels in Foreign CountriesIf you plan on driving in another country out-
side the United States or Canada, the
proper fuel may be hard to find. Never use
leaded gasoline or any other fuel not recom-
mended in the previous text on fuel. Costly
repairs caused by use of improper fuel
would not be covered by your warranty.
To check the fuel availability, ask an auto
club, or contact a major oil company that
does business in the country where you will
be driving.

159 Starting and driving
Engine block heater(standard equipment in Canada, acces-
sory in U.S.)The following are just some of the benefits
to the car and the environment of using an
engine block heater:
 Lower fuel consumption.
 Exhaust emissions substantially reduced
over short runs.
 Reduced wear on the engine.
 Inside of car warms up faster.
The engine heater is effective at outside
temperatures up to +15–20°C. The warmer
it is outside, the shorter the time the engine
heater needs to be connected. Longer than
1.5 hours is unnecessary.
If the car is equipped with a removable,
electrical cabin heater that is not in use, this
should be stored in the luggage compart-
ment.
Driving in cold weatherBefore starting a journey in cold weather
you should check the following:
 That the wiper blades have not become
frozen to the windshield/glass.
 Brush any snow away from the air intake
for the heater system (opening between
hood and windshield).
 It may be advisable to lubricate the door-
lock cylinder (use molybdenum
disulphide, MoS
2) to prevent its freezing.
If the lock has frozen, take care not to
break the key (or use the remote control)
– heat it first or spray it with de-icer.
 Periodically during the winter, add gaso-
line anti-freeze to the fuel to dispel any
condensation in the fuel tank which could
freeze and cause problems in the system.
Keep the tank well filled to reduce the risk
of condensation forming.
If the car is parked outside in freezing
weather, fuel additives (gasoline anti-
freeze) will not do any good as it cannot
remove water that has already frozen.
Park the car in a warm place so that any
ice that may have built up melts, then add
gasoline anti-freeze when filling up the
tank. Condensation is caused by changes
in the outdoor temperature or by the car
being parked alternately in a garage and
outside.
 It is particularly important when the roads
are slippery that the brakes and tires be in
good condition. Check the anti-freeze in the engine coo-
lant, see page 188.
The car´s trip computer will warn you when
there is a risk of slippery conditions. For fur-
ther information on this function, see
page 62.
The car is equipped with tires designed to
provide optimum grip on both wet and dry
roads, although this has been achieved at
the expense of somewhat reduced grip on
snow and ice. For regular driving on snow
and ice, we therefore recommend that
winter (snow) tires be fitted.
Winter (snow) tires, particularly studded
tires (where use is legally permitted), gener-
ally make driving safer on snow and ice.
Acquaint yourself with the legal provi-
sions governing the use of different
types of winter tires and snow chains.
Studded tires are not allowed in some
countries

255 Specifications
Engine oil To meet demands in Saab's extended service intervals all eng-
ines are filled with specially designed synthetic factory fill oils.
Long service intervals, fuel economy and environmental issues
are the base for our choice of oil. By using oils approved by Saab
you minimise the tendencies for oil sludge build, by that protec-
ting the engine from harmful, wear increasing, deposits.Approved oils:
All gasoline engines - Fully Synthetic Engine Oil fulfilling
GM-LL-A-025 requirements.Oil used at, or in-between, service must be approved according
to the engine specified classification to render possible the
usage of Saab Automobile AB specified service intervals.Servicing/Oil changes:To be able to use recommended service intervals the need to
use only approved engine oils is vital.
Use only engine oils
approved for your engine.
Service should be done according
to the recommended service intervals to optimize your engine's
function through out its entire life. Saab Automobile AB will not
take responsibility for any damage that might occur due to neg-
lecting to meet above mentioned requirements.
At your Saab dealers you can find Saab Genuine or Mobil eng-
ine oils. Among those there are oils specially designed to meet
your engines specific needs. We recommend that you, with the
help of our skilled service personnel, choose your oil from that
sortiment.
Other oil companies also have engine oils approved according
to GM specifications. Oils meeting these standards may be
identified as synthetic. However, not all synthetic oils will meet
your engines requirements. You should only use oil that meets
your engines specific requirements (GM-LL-A-025).
Recommended oil viscositiesViscosity is a measurement of the oils thickness. The thickness
influences, among other things, the fuel economy. For best func-
tion Saab recommends:For gasoline engines:SAE 0W-30
SAE 5W-30
or
SAE 0W-40 engine oilExtra engine oil additivesDon't add anything to your oil. The recommended oils are all you
will need for good engine performance and protection.
