1999 Ford F-250 Super Duty Lariat 7.3L Poor Fuel Economy
Posted to Ford Driveability on 3/29/2007 7 Replies

Hi Guys, We've got this Ford that runs great and has no codes, but only gets 6.5 mpg. No fuel leaks, no fluid levels overfull, don't see how this can be with no codes in memory. Any help would be appreciated. Ken
