142 Starting and driving
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-
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
Higher concentrations of methanol than
listed above, or the use of methanol-
blended gasoline without suitable
co-solvents and corrosion inhibitors,
can damage your car’s fuel system,
leading to the need for repairs which are
not covered by Saab’s product warranty.
NOTICE
The engine control module (ECM) mon-
itoring the engine parameters also
stores fault codes.
Under certain circumstances, this may
cause constant illumination of the
Engine malfunction (CHECK ENGINE)
lamp , thus indicating a fault that
must be checked by your Saab dealer,
see page 61.
NOTE: always observe the following two
measures:
• Make sure that the fuel filler cap is
screwed on correctly before the
engine is started. Screw on the fuel
filler cap until you hear three distinct
clicks.
• Avoid driving with the fuel low level
indicator illuminated. The symbol
illuminates when less than approxi-
mately 2.5 gallons (10 litres) of fuel
remains in the tank.
