we have a still stock kl verada awd and we seem to get pretty poor range out of it - not thru fault of the car tho - last tank got us 350ish km and it took 45L to fill back up again.
thats driving it around town 90% of the time too - and i tend to get enthusiastic when driving it too (im only now starting to 'grandma' it to see what sort of range i can realistically get out of the car)

i *only* run BP Ultimate (98 RON) in her - i love using this fuel - all my cars drink it religiously!

i got thru a lot of fuel, because its still a new car to me - so every time i drive it is almost to test its takeoff / cornering speeds etc etc, when the new car 'smell' (figuratively speaking) wears off, i hope to be getting somewhere in the vacinity of 500+ around town using 98ron in town, and a lot more out on the highway.
i also have the a/c set at 22 all the time as well... so that doesnt help much!


is the fuel guage in a kl driven by the computer? ie - the computer will tell you there is LESS fuel in the tank than there actually is, by your driving style?
my partners VZ holden Calais had this sort of 'adaptive' fuel guage, and it used to drive me crazy because it was never an accurate representation of how much fuel we actually have left!
