Have your A/C compressor checked if it's dragging and adding excess load to the engine.

On getting the FC, the only consistent way to determine whether your car is running efficiently or not is to do the full tank method.

thank you sir vinj! though the car is more than 21 yrs old now, would you be able to recommend a surplus shop were i can purchase a compressor if ever it is indeed the culprit?
