I just got my jeep patriot yesterday so I'm a little new at this. i drive it from harrisonville mo to carlisle iowa today. i had to fill up at 228 miles after i had filled completely up before we left. this means i only for 17.5 mpg ALL HIGHWAY! It was advertised at 23 highway. i have read that gas mileage sucks untilyou break in the motor. any thoughts?
