Gasoline Additives - Mercedes-Benz 2008 CLK-Class Operator's Manual

Gasoline additives

A major concern among engine manufac-
turers is carbon build-up caused by gaso-
line. Mercedes-Benz recommends only the
use of quality gasoline containing additives
that prevent the build-up of carbon
deposits.
After an extended period of using fuels
without such additives, carbon deposits
can build up especially on the intake valves
and in the combustion area, leading to
engine performance problems such as:
Warm-up hesitation
Unstable idle
Knocking/pinging
Misfire
Power loss
In areas where carbon deposits may be
encountered due to lack of availability of
gasolines which contain these additives,
Mercedes-Benz recommends the use of
additives approved by us for use on
Mercedes-Benz vehicles.
Refer to Factory Approved Service
Products pamphlet (USA only), or contact
an authorized Mercedes-Benz Center for a
listing of approved product(s). Follow
directions on product label.
