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.

Marine diesel
Heating oil
Pure fatty acid methyl ester or vegetable oil
Paraffin or kerosene
If you accidentally refuel with the wrong fuel:
The following compatibility indications for fuel apply to your vehicle:
Refill with diesel fuel containing a maximum of 10 or 20% fatty acid methyl ester by volume (bio-diesel) only 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:
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). When refuelling the next time, the fuel tank can be filled normally again.
