Based on ur car, there should only be 2 O2 Sensor. Unless it's faulty or have clocked more than 100k km, changing it would not have impact on comsumption figures.

Spark plug, air filter, properly maintained engine would prob given u more mileage. Also, the O2 sensor r not cheap and make not even offset the cost of rising petrol.
