2008 SAAB 9-5 fuel additives

149 Starting and driving
occurs, return to your authorized Saab
dealer for diagnosis. If it is determined that
the condition is caused by the type of fuel
used, repairs may not be covered by your
warranty.
Additives
To 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
corrode metal parts in your fuel system
and also damage the plastic and rubber
parts. That damage would not be
covered under your warranty.
Some gasolines that are not reformulated
for low emissions may contain an
octane-enhancing additive called methylcy-
clopentadienyl 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 Countries
If 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.95_US_M08.book Page 149 Friday, May 11, 2007 1:06 PM

172 Starting and drivingEngine block heater3
33 3The 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 58–68°F (+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 cool-
ant, see page 195.
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 68.
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.

263 Specifications
Engine oil To meet demands in Saab's extended service intervals all
engines 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 minimize the tendencies for oil sludge build, by that
protecting the engine from harmful, wear increasing, deposits.
Approved engine oils:
For all gasoline engines - synthetic engine oil - approved against
the GM-LL-A-025 specification. To benefit from Saab´s speci-
fied service intervals, pleasure ensure to select a synthetic
engine oil approved against GM-LL-A-025.
For optimum performance Saab recommends the use of Saab
Long Life Turbo Oil SAE 0W-30, 0W-40, 5W-30 or 5W-40.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
neglecting to meet above mentioned requirements.
At your Saab dealers you can find Saab and GM Genuine or
Mobil engine 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 selection.
Other oil companies also offer engine oils approved against GM
specifications. Oils meeting these standards may be marked as
synthetic. However, not all synthetic engine oils will meet your
engines specific requirements. Please ensure only to use syn-
thetic oils approved against your engines specific requirements,
i.e. GM-LL-A-025.
Extra engine oil additives
Don't add anything to your oil. The recommended oils are all you
will need for good engine performance and protection.
