I am using this car from last 3.5 yrs. And I always calculate the avg on each refilling. Generally car gives
15 km without ac in city
14 km with ac in city
Both in lahore and key is to switch it off on signals. At max I have got 17 km/l in city without ac and 15.5 with ac.
On highways(motorway) it totally depends on ur speed.
At 100 - 110 km / h
It gives around 18 km/ l without ac
16 with ac.
At 115-120
Gives 15.5 km/l without ac.
12-12.5 with ac.
On gt road, max with ac which I got is
19 km/ l with ac
20 without ac.
Car is tuned after every 15 k running from suzuki...
