Hi guys Just come back from petrol station and I did a really stupid thing today. Firstly I fill up 0.39 Litres of petrol into a diesel car by mistake and as soon as I realized it was petrol I stop straight away. I then filled up with full tank of diesel and hopefully that will help to mix up the petrol. The question is will this damage my engine or give me some problem later on?What should I do as I am very worried about this. Any help will be much appreciated.
