You cannot make such blanket statements....using premium and getting better milage or performance DEPENDS on the car you put it in, and is not necessarily the same result for all cars.

You run premium in your Yaris sewing machine motor, it will get worse milage, it will produce less power, and it will create more emissions, and burn dirtier. Leave the Premium for the cars that are engineered for it, high compression engines, higher performance cars....premium is not for our Yaris...save your money. Come on guys, get real!
