@wittykranium: I have a SeSaloon, done about 20k on the clock.
It has stock 14" tires. It is auto.
Initially we used to get about 60-65 km per fillup (60 cylinder). After about 2-3month use, we have now been able to get about 80km to a fill. I dont know for some reason, it does not give great mileage.
BTW the above are with A/c, and very normal driving, without revving it all the way.
I think its due to the transmission that this car does not do so well.
Last but not the least, the mileage greatly varies, depending on where you get it filled from and what kind of pressure is being generated.
