Gasoline Engines
Your Mercedes-Benz SLR vehicle is
equipped with both a three-way catalyst
and a closed loop oxygen sensor system
to comply with current exhaust emission
regulations. Keep your vehicle in proper
operating condition by following our rec-
ommended maintenance instructions as
outlined.
The following has to be adhered to:
a) In all gasoline engine models, use
only premium unleaded gasoline
with an anti-knock index of at least
91 (as displayed on the pump) un-
less otherwise specified. Damage to
the engine could occur if premium un-
leaded fuel is not used. Refer to the
Operator’s Manual for special precau-
tions.
b) Leaded gasoline should not be used
under any circumstances. Damage
to the emission control components
will result.
c) The specified engine maintenance
jobs have to be performed com-
pletely and at the required inter-
vals. Correct ignition timing and
properly functioning spark plugs for in-
stance are important for the service
life of the catalysts. Failure to properly
perform the specified maintenance
jobs may adversely affect the emis-
sion control system on the vehicle and
reduce its service life.
