First of all I love this car very surprised that a car of this size and weight will get the mileage that I'm getting. I have over 5600 to date and have 41.3 avg for city/hwy driving. One thing I have noted on hwy and city driving is that the car and scangauge avg are not the same, but at tank end the scangauge avg tank is right on, and car seems to be 1 + mpg higher. (please note that I don't reset till tank end) All so that the scangauge will have a higher 45 to 47 avg. on the city/back way home, and the morning hwy run to work I will see 40 to 42 avg. the best I have seen driving down the hwy with ICE on is 29 to 30 on the scangauge would like to know what Wayne seen on their road trip last year with the Kia or last month with hyundai. Thanks for all the info on this site Dave.
