My GSX is Carbie & the average value is derived from two consective full fuel tanks during my recent trip to Rohtass Fort from Lahore
BTW it was my first high way trip on that bike & the purpose was to evaluate the bike performance on long tour. The overall response was good so i think some more optimisation in fuel system, air intake, & ignition systems can improve milage on high way.
As a target my considerations are to achieve ~18Kmpl so lets see how much i can manage to get from it on my next trip.
As far as cars are concern i have achived following values,
Suzuki Mehran ~17Kmpl Econo on high way
Cultus VXR 1000 Carbie 13~14 Econo in city wid AC
Alto VXR 1000 carbie 11~12 Econo in city wid AC
Fiat Uno 1.7D 13 Econo in city
Fiat Uno 1.7D 12 Econo in city wid AC
Fiat Uno 1.7D 19 Econo on Highways
Fiat Uno 1.7D 17 Econo on Highways wid AC
