I run 91 Octane, go 76 miles per day, mostly highway at 75 - 85 mph and get 350-360 miles per tank, average about 23mpg.

Can't complain with 300+ hp!

If I kept it under 75 mph, I bet I could get close to 400 miles on a tank.

6 speed of course.

i just got 163 miles on the last tank, although i think my sending unit is messed up, and i only drive a couple miles at a time, always stop and go traffic. Oh well, doesnt bother me too much I guess.

yeah im with the drive 4 miles and back crowd, and im getting like 13, but even driving farther now, my gas mileage has gone down, its in storage now, but i would say right before i hit the track, weather was cooler and better DA, i couldnt even beat my previous best while everyone else was doing better, better traps and ET, so i knew something was up, because how the hell can the car perform better in the dead heat of summer than a cool fall day!! so the car isnt running as efficient, not sure whats next.

I guess i shouldn't be complaining. Just got 18mpg with 11.67 gallons on a 217 mile trip to the Charger vs. Dolphin game. All highway miles, A4, 373's, 11" ZR1's, 70k miles, and driving at a consistent 80mph, at times hitting an excess of 100mph!

I get about 13-14 in the city, which is pretty bad. Are there any performance mods that can push that up about 1-2 mpgs? Now looking for much.

i doubt its an o2 unless its throwing a code, From what ive seen on here, people who have heads/cam, bad o2s get better mileage than me and im a pretty much stock car, it seems some cars dont get good gas mileage regardless of tuneup.

FWIW, the O2's won't throw a code until they are really bad. As they go bad, mileage will get worse up to the point when they finally throw a code and become obvious.

Scan the computer, sensor 1 bank 1 or bank 2 would be the o2s before the cat and sensor 2 bank 1 or bank 2 would be the ones after the cat

Not 100% sure but i beleive if its bank 1 its driver side and bank 2 is passenger side
