I'm concerned because despite my attempts to maximize my mileage, I have been getting low (compared to the others on this site), and decreasing mileage over my first three tanks of gas. My average just fell under 30 mpg. Is it possible there's something wrong with my specific car? Or is there maybe something I'm doing wrong in terms of my driving? I mostly drive in San Francisco, so perhaps this has to do with all of our hills. But all over San Francisco are Camry Hybrid billboards that say "40 mpg City. Any city." It certainly gripes me every time I see it. Either it's false advertising, or this problem is unique to me....

Is there any way to use this database to see other Camrys in SF? And other ideas/thoughts? Thanks!
