I just put ~11 liters of Petrol in a Audi Q7 2008 with a tank capacity of 80l, I immediately filled it up with diesel and drove about 10 km to my hotel. Some sources say it’s fine if I keep topping it up, others say I’m screwed. Am I ok? Should I add oil?
Don’t drive it hard. Top off with diesel often. Should be okay once you run a couple tanks through it. Change the fuel filter too.
