samir can these mileage test kits be tampered with? cause when i was having fe issues the car was putting out 10km/l max on highways these showroom guys used the kit to test and they stated car giving 18-22km/l but my mid was showing 10km/l.
anyways i find no difference in fe based on temperature settings my ac is always at 'lo' setting, just rarely when theres friends who feel cold i put it at 23-25 but i noticed the compressor doesn't shut of the ac maintains the temperature by mixing in hot air from the heater core, i noticed the sound of the ducts opening and closing at intervals its pretty faint though.
but city driving giving you 17 is awesome. Do post the driving style you follow so we guys can try adapting to it. You know hyundai cars are very sensitive to the style and fuel quality so for some guys hyundais give best fes while others terrible. Out on this forum one guy brought a crdi verna and sold it a couple of weeks later due to bad fe. btw
after washing the condenser the ac is back to being sweet! guess id ned to do this frequently as almost the entire front of the ac condenser is exposed to all the muck.
