mid 20's if your easy with it. The 3spd automatic is direct in 3rd and those early ones do not have a lockup TC. Carburetors on those things were garbage when they were rolling off the transport trucks. The non feedback version are somewhat better.

Fuel injection and a manual transmission really help the 2.2 with mileage.

I have a 4dr Shadow manual transmission (2.2 TBI) and I get around 27.5 in local stop-go driving. Ethanol polluted gasoline doesn't help anything.
