    "This is a fantastic product. I bought it thinking I may get a slight increase in gas mileage, but it was a little more than slight. Based on calculations, I've got approx. 3.5 mpg better. the only thing disappointing was the handling of the car (acceleration,) didn't change, but I didn't expect much to begin with."
