Notes on fuel grades on vehicles with diesel engines

General notes

Observe the notes on operating fluids More.

WARNING Risk of fire from fuel mixture

If you mix diesel fuel with petrol, the flash point of the fuel mixture is lower than that of pure diesel fuel.

While the engine is running, component parts in the exhaust system may overheat without warning.

Never refuel using petrol in diesel engines.

Never mix petrol with diesel fuel.

NOTE Damage due to incorrect fuel

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

Only refuel using sulphur-free diesel fuel that conforms to the European standard EN 590 or an equivalent specification. In countries without sulphur-free diesel fuel, only fill up with low-sulphur diesel fuel with a sulphur content of less than 50 ppm.

Never refuel with:

petrol
marine diesel
heating oil
pure bio-diesel or vegetable oil
paraffin or kerosene

If you have accidentally refuelled with the wrong fuel:

do not switch on the ignition.

Consult a qualified specialist workshop.

The following compatibility mark for fuel applies to your vehicle:

For diesel fuel with a maximum of 7% by volume bio-diesel (fatty acid methyl ester)

In accordance with the European standard EN 16942, you will find the compatibility marks for fuel in the following places:

on the vehicle on the instruction label in the fuel filler flap
throughout Europe on the fuel pumps or pump nozzles suitable for your vehicle

XTL-compatible vehicles

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:

For diesel fuel with a maximum of 7% by volume bio-diesel (fatty acid methyl ester)

For paraffinic diesel fuel

Refuel with paraffinic diesel fuels to EN 15940 only if the appropriate compatibility mark is present in your fuel filler flap.

Notes on low outside temperatures

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, only refuel using a small amount, e.g. to reserve level. When refuelling the next time, the fuel tank can be filled normally again.
