As my car having 60wl cylinder, so it gets fill in approx 300 RS and i am getting millage :
In city with full time Ac on, normal 4 ppls on board , no lugage. Approx on normal smooth driving, 150 km .
On motorway i am getting with 4ppls and not heavy lugage approx 190km millage with All Ac on.
If driving style is smooth not rash, then ...... :P)
Top speed i got on motorway was 160 without Ac but the Rpm was at 4500 and i then decided not to try more but i have doubt it can reach 170-180 , but as i am not that kinda fast and furious guy so i withdraw going further.
