I've had my new Kia Soul 4u Automatic for a week now, and I'm put 1000 kms on it. Overall, I love the car but the gas mileage is so far not as advertised. I was told by the dealership that it takes sometime to work itself in, but I was wondering what everyone was getting on a tank. I've filled up 2 times now and I drive mostly highways. First tank it got 340 some kms and the second tank I got 320 kms. Both are far off the 43 miles per gallon they advertised. Anyone else get better or worse mileage?
