Cheap has nothing to do with it. Perhaps you don't mind if you're promised one thing and get another, but I don't like it. Regular fuel was recommended when we bought the car. Regardless, we ran it for a couple of months on premium fuel and it made no difference to the hesitation problem, so that isn't the answer. (It does improve city gas mileage, however) If you ask a service advisor who is honest, they'll tell you that there's a design flaw and they don't know how to fix it.
