If you notice the mistake at the station, coordinate a safe waiting location with its staff without handling the fuel. If you have already driven, say so: it changes the checks required. Use Daba to explain the situation and request an equipped professional without trying to diagnose the damage yourself.
Information to prepare
- Keep the refuelling receipt if available.
- State the required petrol or diesel and the fuel added.
- Say whether the engine ran and the vehicle moved.
- Share the station name and access to your location.
What to watch for
Do not add another fuel to try to correct the mixture. Do not start the engine; arrange suitable draining or diagnosis with a professional.
