I drive mixed highway/city with 4.10s and get 20mpg assuming I don't get it sideways every chance I get. About 2300 rpms @ 70mph on the highway. Before the gears I only think I got 22mpg, so the change wasn't really noticable.
i have 4.30s... mpg went up in the city due to use of 5th gear (1400rpmish at 45mph). went down a little on the highway, but not too bad. probably 2 mpg... at 15 gallons, that's 30 miles difference... that's about 3 dollars worth of gas... a price well worth the gears IMO...
