I misfuelled my C-Class - what should I do?
I filled my Mercedes-Benz C250 with petrol instead of diesel. I realised when the engine began to falter after about 25 miles and stopped the car. Mercedes-Benz recovered the car and took it to their Norwich workshop where they drained the tank, bled the lines and replaced the fuel filter. I filled the tank with Shell V-Power for my journey home - the car ran OK.
1) Will there be long term damage?
2) Should I do anything else (use an additive when I next refuel or get the fuel filter changed again before the next service - due March 2015)? I plan to keep the car for the next five years.
The man in the recovery truck said it was his third mis-fuel in a week and the service department at Mercedes-Benz Norwich said it was their second in two days - why can we put men on the moon but not stop idiots like me doing something so daft?

Petrol sits on top of diesel in the tank and the fuel pick-up is at the bottom. But if any petrol did reach the high pressure fuel injection pump there could be damage. So stick with high lubricity diesel, preferably Shell V-Power for your best chance of survival (pays for itself in better mpg anyway).
Many new cars have misfuel prevention devices. All Fords, all Hondas, all BMWs, etc.

Much improved interior quality. More refined and better to drive than predecessor. Strong 2.0-litre four-cylinder diesel engines on facelifted cars.
