E 200, E 250, E 400 4MATIC: Observe the information on sulphur content on the information table in the fuel filler flap:

NOTE Damage to the emission control system caused by fuel with a too high sulphur content

Only use sulphur-free fuel (sulphur content ≤ 10 ppm).

All other models: If the available fuel is not sufficiently low in sulphur, this can produce unpleasant odours.

Recommended fuel: the recommended octane number for your vehicle can be found in the information table in the fuel filler flap More.

Alternative fuel: as a temporary measure, if the recommended fuel is not available, you may also use unleaded regular petrol with an octane number of at least 91 RON . This may reduce engine output and increase fuel consumption.

Never refuel using petrol with a lower RON .
