Car A/c Thermostat adjustment-Effect on Car Mileage
When the compressor is working, it would put additional load on the engine and that would definitely increase the fuel consumption. Futrhermore being a low powered engine, the difference could be more than others but you should not be experiencing more than a few % difference. However driving and road conditions makes a lot of difference with the additional load on the low powered engine running the A/C.
Previously when A/C was not that efficitn, the compressor would be working less of the time and now it has to work for longer periods so some increase in fuel consumption is expected.
