Hi, My Muchlis I hope you are doing well. I'm sorry to hear that the fuel system is contaminated and I totally understand how worrying this can be. Can you tell me how far you have driven with the petrol in the system?

Expert:  Kevin replied 8 days ago.

ok, I'm sorry to say the concern here is that petrol in diesel can cause a significant amount of damage to the internals of the diesel injection pump which can then contaminate the system with small metal particles from the damage to the pump. I would strongly recommend that the tank is drained and filled with fresh diesel and the fuel filter replaced. This will lower the risk of any damage occurring within the system. I know this is not the best news and may be very worrying but this is the best action to take to avoid some very large costs if damage occurs. Thank you again for visiting JustAnswer, please let me know if you need me to clarify anything or if you have any additional questions-I am happy to help!
