There was 1/4 tank when I stopped to fill up. Put 7l unleaded and then filled to the top with diesel. So it's 7l unleaded in the tank and the rest is diesel.I would have stopped at the 7L petrol stage and had a misfuel service come and empty the lot and start again.
Could do some/a lot of damage with the mixed fuels. What ratio of Diesel/Petrol do you think is in there now?
It doesn't take a lot of petrol in a diesel to start causing damage I think.
Others may have brighter news (from their experiences).
