'98+ cars have a lot more different than just the transmission. They have more economical and powerful engines thanks to the DIS and VVTi, better aero, and continue to be lighter than the 1st generation cars by several hundred pounds.
I have heard of '98-00 LS400's getting as high as 27-28 or so mpg on sustained highway cruises at lower (55-65mph) speeds. That nudges over 600mi on a '95-00 tank.
