We picked up our ebony SX Telluride 6 days ago and love it. I know the sticker said 23/25 mpg for gas our model and the dashboard keeps saying between 16-18 average mpg. Is this maybe because it is new? We do not have 4wd, that is why our gas mileage was supposed to be a little better then the 4wd. Thank you!!! PS-haven't read the owner's manual at all yet but going to try to get around to it today.
