lmao at you mileages.
but to help mileage (but decrease traction in the winter) i run high tire psi. i clean my air filter regularly.
i've also noticed better mileage after seafoaming my car. make sure you have to brakes dragging. don't haul around lots of weight. if you have a big stereo turn it down.
plugged cat will decrease mileage, but should throw a code?
check spark plugs, could be fouled.
and honestly 20mpg city mileage isn't too terrible for a v6. i barely get 25 in my 4cyl with a standard. and i dont really drive that nicely.
check all those things. easy to do, and cheap for the most part.
watch the way you drive too
