Notes on fuel grades for vehicles with a gasoline engine

Observe the notes on operating fluids.

NOTE Damage caused by the wrong fuel

Even small amounts of the wrong fuel could result in damage to the fuel system, the engine and the emission control system.

Only refuel with low-sulfur unleaded fuel.

This fuel may contain up to 10% ethanol by volume. Your vehicle is suitable for use with E10 fuel.

Never refuel with one of the following fuels:

Diesel
Gasoline with more than 10% ethanol by volume, e.g. E15, E85, E100
Gasoline with more than 3% methanol by volume, e.g. M15, M30, M85, M100
Gasoline with additives containing metal

If you have accidentally refueled with the wrong fuel:

Do not switch on the ignition.
Consult a qualified specialist workshop.

If the available fuel is not sufficiently low in sulfur, this can produce unpleasant odors.

Only refuel with fuel that has at least the octane number specified in the instruction label in the fuel filler flap.

If you want maximum engine output: only refuel with unleaded premium grade gasoline with an octane number of at least 91 AKI/ 95 RON.

As a temporary measure, if the recommended fuel is not available, you may also refuel with unleaded regular gasoline with at least 87 AKI/ 91 RON. This may reduce engine output and increase fuel consumption.

Never refuel using gasoline with an even lower RON.

NOTE Premature wear caused by unleaded regular gasoline

Unleaded regular gasoline can cause the engine to wear more quickly and impair longevity and performance.

If unleaded premium grade gasoline is unavailable and you have to refuel using unleaded regular gasoline:

Only fill the fuel tank to half full with unleaded regular gasoline and refill as soon as possible with unleaded premium grade gasoline.
Do not drive at the maximum speed.
Avoid sudden acceleration and engine speeds over 3,000 rpm.

Information on additives in gasoline

Observe the notes on operating fluids.

NOTE Damage from use of unsuitable additives

Even small amounts of the wrong additive may lead to malfunctions occurring.

Only add cleaning additives recommended by Mercedes-Benz to the fuel.

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 an authorized Mercedes-Benz Center, 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.

Tank content and fuel reserve
