Hello Terry

the tank capacity on these cars is 59 litres and you can typically withstand 15% petrol in diesel with no issues

so for a 59 litre tank 15% would be 8.85 ltrs

so you should just be alright

providing that the tank is brimmed with diesel afterwards

I'd also reccommend adding some diesel pump treatment to the tank to help with pump lubrication as the petrol attacks the pump and injector seals

something like this
