If I put 47litres of petrol in a diesel Galaxy containing 20

Customer Question

If I put 47litres of petrol in a diesel Galaxy containing 20 litres of diesel already, how far could I expect to drive before seeing a problem? An issue occured 24hrs after fuelling and after 30 miles of driving? I am not convinced that is possible.

hello I'm sorry to say that its very likely that the fuel pump and / or the injectors will have been damaged as you shouldn't drive it more than 5 to 10 miles, with this sort of thing you can get away with about 15% mix of petrol in diesel as petrol is very damaging to the pump seals as it drys them out as the next step I'd drain the tank completly and refill with fresh diesel and also apply a fuel treatment to add some lubrication to the pump sorry its not better news but keep an eye out for a lack of power in the future, if you feel the engine no longer pulls as it should then I'd get the pump pressure measured
