First off, it is 20 years old. First I would do a compression test, if good. The next thing I would do is a complete tune up. Cap, rotor, plug wires, plug, air filter, fuel filter, and an oil change with filter. After this I would start it and get it to operating temperature. Remove the air plenum from the carb/throttle body, Rev it up a bit (not letting it die) and pour a small stream of water in the throttle body for a minute or so. Doing this cleans the top of the pistons and valves from carbon build up.

Consider getting this info on ADDING Hydrogen power to your fuel. Raises fuel mileage 25% to 50%+.

Imagine if it works - raise your fuel mileage to 21+ in stop n go driving, up tp 35+, maybe 40 mpg with a steady low cruise on the highway, at 60-62 mph.
only costs $170-$200 if you can do it yourself, if you can change pcv / oxygen sensors / plugs / fuel filters, YOU can do it.
Else, pay a mechanic an extra $200 for 2 hours work for him/her to install in 45 minutes.

it can be some reasons mybe cylinder head, inlet valve worn out.
it can be cuporator valve releasing more petrol into the inlet.
Brakes it can be. check contacpoint.
SOURCE: high fuel consumption
change o2 sensors every 60,000 miles and use iridium plugs they will outlast engine.
check engine light will not come on until sensors are completely shot,this also goes for your mass air flow,had same issues with 99 beetle happened at 80,000 miles,changed all three items ended up with 35mpg after getting 24mpg before fix.parts are cheap on ebay.
SOURCE: high fuel consumption. only 200 miles per tank
it has gotta be the o2 sensor, map sensor, or the mass air flow meter.............. these are the main inputs to the computer that controls the fuel control....let me know how that works out please
