Hi all, I have 1,100 miles on my nitro, it has the 3.7 engine in it, I am only getting 17.4 miles a gallon staight highway driving. I am going by filling up the gas tank going on a road trip doing 72 miles per hour with cruise set, comeing back home and filling up gas tank again. Window sticker says 23 highway 17 city, this is way off I figured I would at least get 20 mpg highway. Will my gas milage increase as the engine gets more mileage on it or did I buy a gas hog?
