AT transmission reduces mileage by about 10%
However as earlier pointed out it reduces fatigue to half or even less in city traffic and 10 fold in stop and go traffic. Once you use an AT, most kind of just get addicted to it and don't want to switch back to manual just for the convenience AT offers. It is totally worth the slightly reduced fuel efficiency.

Hi,
AT versions delivers mileage lesser by app 1 or 2 kmpl max. The advantage of AT version is the easier operation and generally problems like noisy gearbox, engageing problems will be much lesser compared to MT versions.
