Mercedes-Benz recommends that you use fuel
brands that have additives.
In some countries, the fuel available may not
have sufficient additives. Residue could build up
in the fuel injection system as a result. In this
case, in consultation with a Mercedes-Benz
service centre, the fuel may be mixed with the
cleaning additive recommended by Mercedes-
Benz. Be sure to observe the notes and mixing
ratios specified on the container.
