Yea. What you read is bogus, unless you are a timid 80-year-old driving on perfectly flat ground in cold weather without stopping.
With my supercharger, I usually average about 270 miles per tank (I don't usually run it bone-dry before fill-ups) in the city and MAYBE up to 290 on the highway. Even though it's supercharged, most naturally-aspirated Tacos will exhibit the same mileage.
One time, I got 315 out of it by driving 65-70mph through the desert, but when I filled up, the tank took 17.6 gallons! That means I ran the tank almost completely dry, so anything over 280 is usually pretty damned good for mileage between fill-ups. <img src="/forums/images/graemlins/kewl.gif" alt="" />
