Just bought a 2010 Canyon SLE 2.9 4x4. I had read the estimated gas mileage reviews and they all said 18-21 city, and 25 Highway. I drive very conservetally, and all I can get is 15 mpg. Is this standard or can there be something wrong . It drives very nicely. Plenty of power, smooth idle. I read that maybe thermostat could be running cold but temp gauge is almost at halfway. Another advice was to reset the ECM by pulling the fuse, but I do not see that fuse. Any help will be appreciated.
