The mileage I am getting is 14 mpg in the city, hwy about 18. It used to be at least 5 to 6 mpg higher. The car has not had an engine tune up for over

100,000 miles. Could this be the problem, the mileage just went south so quickly? I have 168,000 miles on car. The car does not miss or sputter, its just sucking up a lot of gas. Any suggestions?

I would check the air cleaner - could be that simple.
