“I find myself having to having to add oil every two fill ups. From 500 hundred to 1000 miles.this rate of oil consumption very excessive and if I would have been advised at the time of purchase I would have not bought the car. The dealer and Porsche USA says this is normal. But I have another Porsche that doesn't use oil. They have to add oil three times since I bought the car.unacceptable!.”
