[quote Filliam H. Muffman]I agree that using premium in a car it is not designed for will not help for something like this.
For smog tests you do want to use Premium. It helps to keep the NOx down and slows the burn. By the numbers, I would suggest driving the piss out of the car prior to the smog test. Include 20 minutes on the freeway and a little Heet (Product name) wouldn't hurt.
