That's in the ballpark.
~23-24 mpg mostly city, mixed;
~28-29 mpg highway.
My best mileage is around 66 mph. My car is an AP1 with an '04 transmission and diff with 4.57 gears, + Comptech intake and exhaust. My best stock mileage was at ~69 mph. My car sees VTEC and the redline frequently. Around 3 out of 10 redlights see a little 1st up to 3rd redline fun (redline in first and second, back off in third). Every clear on-ramp sees 1st-4th (backing off in 5th) redline enjoyment.
However, my overall gear setup allows me to row through 5th gear by 35 mph (~3900 RPM up-shifts), which probably accounts for my better than average city mileage.
If you keep it mostly below ~72-73 mph on the highway, you'll see better mileage. Above that - you're just burning gas to go fast. Ever been passed by the same car several times on a long road trip? The extra stops due to the need to fill up more often kill your time.
The difference in a cross town run at 80 vs 60 mph in a city as big as Atlanta (if you can maintain those speeds) will typically only save you ~10-13 minutes, but will cost you almost an extra gallon for that fraction of time. That's the equivalent of paying over $24 per hour for the effort (based on $4.35 per gallon for premium).
I just made a road trip from Pensacola to DC; DC to Norfolk; and Norfolk back to Pensacola; and I can't tell you how many idiots passed me in minivans, SUVs and trucks (not to mention the countless A-holes in big rigs who tried - I don't let them pass me, they just pass and slow down, which cause untold aggravation
). I had my cruise set at 70-73 or 76-77 mph (depending on the zone). I bet every one of those knuckleheads complain about the price of gas 
. Guess what - they can suck it! Their overly consumptive driving style (not to mention choice in vehicles) are a big part of the problem (on the micro and macro scale). Slow down on the highway to between 55-75 mph (depending on how 'slick' your vehicle is) and you'll see a significant improvement in mileage.
One of my friends who owns a Corvette says he sees up to 32 mpg if he keeps his C-5 below 75 mph, but his mileage drops by 8 mpg if he drives over 85 mph. "No sh*t!" I told him sarcastically (we're both military pilots and went through the same aero classes many moons ago). The combination of form/induced and parasitic drag increases at an almost logarithmic rate above ~35-40mph in cars. The larger the vehicle, the larger the effect. Take a face on shot of your vehicle and black it out to make a silhouette. Multiply the area by 60% for a more wedge shaped front end and 75% for a blunter nosed vehicle - and that's approximately how much of a flat brick-wall you

The gas mileage you are getting is average for this car. When I drive to work during the week I take roads no more than 55 mph and get around 280-300 miles per tank. I noticed that because of the gearing of the car going 70-80mph on the highway will get you less mpg just because of the higher revs.

Comparing "miles per tank" is not very technical and can vary wildly depending on what one is using as a value for the "tank". My "tank" value would be low as I refill when I'm down to a 1/4 tank left. Otherwise something to chat about when one has time to kill.
