Q: Terrible gas mileage

asked by on

I get about 18 mile per gallon in the city and just driving back and forth to work (about 5 miles) I'll have to refill once every other week, even more when the A/C is on. What would be the cause of such terrible mileage? I recently had my oil changed and new tires put on, I've used fuel injector cleaner and even installed a new PCV valve and it still does nothing to help.

My car has 188000 miles.
My car has an automatic transmission.
