I get 12 - 14 mpg on the highway, towing a 5,000 lb trailer at 80 mph! '98 ML320, 129K miles. Normal is 17 city, 20 highway, driving 60 on the two lanes and 80 on the Interstate. My wife is not really a light footed driver, and I'm WFO all the time. I'm very surprised the new ones do so much worse. Could it be they get better after they "loosen up" a little?
