hmmmm . . .i wonder if you track / calculate it yourself if it would be similar to the cluster readout. . . ?Mines been averaging 23mpg since I got it. I can get 30-31 on long hwy trips but mixed or mostly city I don't get any of the advertised mileage. Still love the car but I took it to hyundai 2 times to see if there was something wrong like a leak in the hosing or turbo piping etc. Both times they told me its fine. They recommend I try premium gas and I ran 1 tank with very similar results like 1 to 2 mpg difference. So I dunno what I'm doing wrong.
