Check the emissions. O2 sensors, catalytic converter and so on.

Will the catalytic converter use up the gas??

It can when it gets plugged up. The O2 sensors when defective will send the wrong information to the ECU (the car's computer) and give it a gas rich mixture. Do you have any lights on on dashboard?
