I PURCHASED MY SENTRA NEW IN MARCH 2012. AT THAT TIME, MY GAS MILEAGE WAS NORMAL, AND AS ADVERTISED. WITHIN THE YEAR, I WENT FROM 30MPG AVERAGE TO 27. EVERY YEAR SINCE THEN, IT HAS GRADUALLY GOTTEN WORSE, AND I AM NOW DOWN TO 23MPG, REGARDLESS OF THE TYPE OR GRADE OF GAS I USE. IT'S ACTUALLY WORSE WITH PREMIUM GAS. I HAVE DONE ALL MAINTENANCE ON THE CAR ON TIME, REGULAR OIL CHANGES, ETC. I'VE COMPLAINED TO THE DEALERSHIP MULTIPLE TIMES, AND THEY CLAIM TO FIND NO PROBLEMS WITH IT.
