OK its a 61 ltr tank on this car and you can get away with about 15% petrol in diesel which would be 9.15 ltrs in this tank

so if you've paid about 1.4 euro / litre for the petrol then this is about 10.5 ltrs so you're just over the limit

So you can either siphon out about 8 ltrs and then fill back up with fresh diesel to dilute it sufficently

or if you put 9 ltrs or less petrrol in then your'e fine as you are

either way I'd suggest adding some diesel additive to help the pump with the exposure to petrol

this is a good one
