gas mileage
also you dont have run through all the gears, try different patterns whatever is easiest to keep the rpm's down. ill go 2-4-6 sometimes
btw, I have a lid and loudmouth and they did not help gas mileage
Spark plugs
New O2 sensors
air filter (surprising how a dirty one can hurt fuel economy)
fuel filter
tire pressure (plays a good role in milage)
And as stated,keep the rpms low...Under 2K.I use 4th alot around town cruising at about 35mph or so and get pretty good milage...
Another odd thing I have noticed out of all the F-bodies (4th gens) I have had is,if you top off the tank,and drive a little "old ladyish" you can go for ages before the gas guage gets below the "F"...Once it gets below the "F" its all down hill from there!LOL!
Maybe try a 2nd car as a Daily driver if gas is really becoming an issue in your situation...good luck!
