jeez, man. I have an 05 4x4 S MT, about 13,000 miles on it, and I get over 300 miles on a tank with city driving. I drove from San Antonio, Tx to eastern Oklahoma on one tank of gas...I dont' know how many miles that is, but I think it's over 400. I really make an effort to keep the rpms below 2500 (2000 if possible), and throw it into neutral when ever possible. It helps a lot...at least gas prices are going down here...under $2.00 now! weeeee!
