If you mix diesel fuel with petrol, the flash point of the fuel mixture is lower than that of pure diesel fuel.
Even small amounts of the wrong fuel could result in damage to the fuel system, the engine and the emission control system.
Petrol
Marine diesel
Heating oil
Pure fatty acid methyl ester or vegetable oil
Paraffin or kerosene
If you have accidentally refuelled with the wrong fuel:
Impurities in the fuel can lead to malfunctions of the fuel system.
The following compatibility indications for fuel apply to your vehicle:
Only refill with diesel fuel containing a maximum of 10 or 20% by volume fatty acid methyl ester (bio-diesel) if the corresponding compatibility mark is present in your fuel filler flap.
On the vehicle on the information label in the fuel filler flapMore
Throughout Europe on the fuel dispenser or pump nozzles suitable for your vehicle
Refuel with paraffinic diesel fuels to EN 15940 only if the appropriate compatibility mark is present in your fuel filler flap.
Alternatively, you can also refuel with paraffinic diesel fuel (e.g. HVO = hydrogenated vegetable oil, GTL = Gas-To-Liquid) that complies with the European standard EN 15940. Paraffinic diesel fuels are collectively known as XTL.
In accordance with European standard EN 16942, the following fuel compatibility marks apply to your XTL‑compatible vehicle:
Mercedes-Benz approves the use of B10 fatty acid methyl ester (low-sulphur diesel fuel with a maximum of up to 10% by volume fatty acid methyl ester) for all vehicles with Euro 5 diesel engines with Common Rail Direct Injector (CDI).
Pure fatty acid methyl ester and diesel fuel that has a higher percentage of fatty acid methyl ester (e.g. B20) could damage the fuel system and the engine.
The identification of the fatty acid methyl ester on the fuel dispenser must clearly indicate that it fulfils the standard for low-sulphur diesel fuel. If the identification is not clear, do not refuel.
If you use diesel fuel with a sulphur content that is too high, the emission control system may be damaged.
Only refuel using commercially available diesel fuel with a maximum sulphur content of 50 ppm. Fuels such as fatty acid methyl ester FAME (bio-diesel fuel), marine diesel, domestic heating oil, etc. are not permissible as diesel fuel mixtures.
Vehicle without diesel particulate filter: In countries in which only diesel fuel with a higher sulphur content is available, the vehicle's engine oil change is performed at shorter intervals. Further information on oil change intervals can be obtained at a qualified specialist workshop.

Refuel your vehicle with as much winter diesel fuel as possible at the beginning of winter.
Before switching to winter diesel fuel, the fuel tank should be as empty as possible. When first refuelling with winter diesel fuel, keep the fuel level low (e.g. to reserve level). The next time you refuel, fill the fuel tank again normally.
