Exactly. If you drive 20,000 miles a year, and get 25 mpg, the required premium gas will cost you a whopping…$160 extra.
Since cars that take premium gasoline are not bargain econoboxes, I have never understood why people obsess over this. If you’re going to notice spending an extra $160 a year, perhaps you shouldn’t be thinking about springing for that Lexus in the first place.
