Maybe I'm missing something, but how does manually shifting affect your
highway mileage? Speed would be the bigger factor, as you should be in top gear all the time (assuming it's not a very hilly area).
FWIW, I get 15-16 in mixed/mostly city driving and 18 (80+mph) - 21 (~65mph) on the highway. Pretty much EPA numbers.
Vehicle now has 8,500 miles on odometer.
