How is your gas milage

I run I-20 between B'ham and ATL about once a week; speed limit changes from 55 to 70 once you cross into Georgia, and I consistently drive about 5-10 over. Filled up (15.2 gal from ABSOLUTELY empty) in Birmingham and made the trip, unfortunately passing the downtown Turner Field exit before the 285 interchange at *5:09 PM on a Friday evening* and paying the price on my clutch foot, plus a couple days' worth of driving normally. Made it to 491 miles before I got to wondering how much longer the gas light would stay on...
So, 491 miles @ 15.2 gal. = 32.3 miles per gallon.
Have I told you lately that I love you, Mazda?
 
i was gettin about 290 per tank. but i just recentally put an obx header on it and with out the catalitic converter the first 100 or so miles i was already at half a tank :/ i put to non foulers on the bottom o2 sensor and im hoping this will fix it cuz the drive to san antonio will kill me!!!

i wouldn't blame the header... i would blame the foot... putting a header should increase engine efficiency which should increase mpg...
 
I got 33 MPG for my first tank in the P5. 90 miles were at 55 MPH - 65 MPH, and the rest were city (~280 miles).
