If gas mileage is not too bad, don't be too concerned about it.
Old car just use more gas because of their worn out engine parts.
You have to rebuild/replace everything to get the same gas mileage.
So many things to check. Here are a few things:
Check and replace spark plugs.
Check and replace fuel injectors.
Replace dirty air filter.
If your engine can't reach its normal operating temperature, replace the thermostat.
Check and replace the O2 sensor.
Check and replace the Coolant Temperature Sensor.
Clean the EGR valve, and check to see if this system is working.
To get better gas mileage, most automatic cars have whats are called torque converter lock up clutches. This clutch must engaged at 40 mph or so to lock up the torque converter.

I found mine somewhere.
You can find it by finding the metal hole that runs from the exhaust manifold to the egr valve, and there is another hole from the erg valve to the intake manifold.
