Why am I getting terrible MPG in my 2010 Ford Fusion? - 1

Added (1). I have a 2010 Ford Fusion with the 2.5 i4 and after every fill up it says that i averaged like 18-20 mpg. How is this possible when the average MPG for the 2010 fusion is like 26MPG. Can somebody help me figure this out please!

Hi simple servicing is essential along with less heavy right boot.

22 city - 31 highway. Cold weather and short trips will reduce fuel economy substantially. If you're making trips of less than 10 miles in cold weather, then 18-20 MPG would be plausible.
