Gasoline Engines

Your Mercedes-Benz vehicle is equipped
with both a three-way catalyst and a
closed loop oxygen sensor system to com-
ply with current exhaust emission regula-
tions. 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 Op-
erator's Manual for special precautions.

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 complete-
ly and at the required intervals. Cor-
rect ignition timing and properly
functioning spark plugs for instance are
important for the service life of the cat-
alysts. Failure to properly perform the
specified maintenance jobs may ad-
versely affect the emission control sys-
tem on the vehicle and reduce its
service life.
