SEPHIA 2000 gas overconsumption

Hello, everybody !

Although it's a good car, my Sephia 2000 automatic "eats" 30% more gas in urban trafic (comparing to what its book says). On the highway it's going by the book... I don't accelerate fast or when it's not necessary (ex:when I am close to the red stop lights or to a waiting line), I avoid the speed variations. I'm not driving too slow, either. Does anybody know what should be the reason of this overconsumption? Any suggestion, advice etc. will be welcome !

Thanks !

there is recall about a seal in the fuel tank, you might want to check with your local dealer... it has something to do with gas mileage
