NHTSA Complaint #11031571 — 2015 PORSCHE 911

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!.
