Depends how much. Strictly speaking you need to not start the engine and have the fuel system professionally drained: Google <misfuel rectification> for your nearest specialist. Less than 10 litres in a 60-litre tank, take a chance and you might get away with it. You need to put a can of diesel fuel treatment with lubricity enhancer into the tank and fill up with superdiesel which has higher lubricity. Then never run the tank below half full for 2000 miles. If you're lucky, the petrol will gradually disperse into the diesel and you'll have no problem. More than 10 litres in a 60-litre tank, don't chance this.
