I'm looking for the number of miles to the gallon for highway driving only. Not really interested in city driving statistics. A friend of mine would be driving the described vehicle from Edmonton Canada to Las Vegas Nevada, a total of 1500 miles or 2415 kilometers. We are simply trying to figure out how many tanks of gas with this vehicle it would take to get there. Also, if anyone knows the approximate price of regular fuel in the U.S. that would be helpful as well. That way we could get a rough idea of the fuel cost involved in driving 1500 miles on the highway. Also, please, no partial answers to these questions, otherwise I'm going to have to sift through 80 answers if you know what I mean ? If you know the answers to all of the above questions, please answer and thank you so much for your help.
