Yes, you're right. But unfortunately the auto is only used for short hops - this was the purpose of buying an auto, for slow speed city driving so that we can stop changing gears every 30 seconds.
For longer, high speed trips the other big car is used.
Khair, Will calculate the mileage on a longer trip though - thanks for your suggestion
This car still hasn't done 600 kms. A bit of running in ( till 1000 kms) will improve the mileage as well.
