Before you get flamed, please use the search function. This topic has been answered countless times.
This is how you search: http://www.google.com/search?hl=en&s...%3Arx8club.com
It really depends on how you drive. Short distances and hammering on it will give you lower MPG, while longer drives at a steady rpm will give you more. I stay around 18 mpg for my city driving and I get 20-22 mpg for long freeway drives with minor sprints here and there.
Hope this helps.

The low mpg could also be an indicator that you need to have your car serviced. And pleasu, use the search feature that chadwisk was good enough to link you to. All your questions have been answered numerous times since the RX8 first came out...

Mine doesn't stop going.... Is that a problem? Stock ECU
Thanks Razz, I forgot about this easy fix.
He was searching, but he was doing it the hard way (scrolling through threads). And he's probably not retarded, just an excited teenager who is new to forums.

I cover most of the topic here: https://www.rx8club.com/new-member-forum-197/new-potential-owners-start-here-202454/
Gas Mileage:
If you are considering, or have purchased, an 8, you will likely have one of 3 opinions on gas mileage:
1) I am buying a sports car, or won't be driving this regularly, so I really don't care about mileage
2) I care a bit about mileage, but I think what I get is fairly reasonable
3) WTF, I am getting terrible mileage, these car's suck! All RX-8's are gas guzzlers.
If you have the first or second opinion, then congratulations and join the club. If you have the 3rd, then keep it to yourself, we aren't interested in listening to it. Gas mileage has been discussed, killed, resurrected, killed again, reincarnated, burned alive at the stake, beheaded, cremated, and BURIED AT SEA. Please leave it there.
The reality is, a healthy RX-8 will get 17-18mpg city, 22+mpg highway. But 'healthy' means completely healthy: healthy coils, wires, plugs, O2 sensors, carbon free engine, good compression, healthy cat (or no cat), good transmission/diff fluid. Let even one of these slide, and your mileage WILL drop, and it will drop fast. If you believe that RX-8s simply can not get this mileage because you have never seen it, then there is only 1 person to blame, and that is YOU. If you don't get this mileage, then there is something wrong with one of the above points. Or with your foot. Your right foot can make the mileage drop quite a bit as well. And I don't mean granny driving as the answer to good gas mileage. Smoothness is more important than speed. Smooth and fast is better mileage than unstable and slow.
People also tend to point at it being a 1.3L engine, and assume that a 240/238/232 hp rotary "2-stroke" engine is as efficient as a 1.3L 4-stroke piston engine (which is probably in the 70-90hp range). This simply is NOT the case.
So if you can't get this mileage, start poking around for what is wrong.
For reference, here is 8,330 miles of mileage data from my Sevenstock trip around the country in September 2010. The lowest tank was 13.99mpg (14mpg basically), and that was in non-stop tight curves on the Pacific Coast Highway where I was having fun blasting along. Note the 4 tanks over 23mpg, 11 tanks over 20.00mpg. Also note how the highway mileage drops as speeds go up. Once you cross the ~70mph range, the wind resistance does start stacking against you more and more. It's easily a several MPG drop going from a cruise of 70 to a cruise of 80+. And those were probably closer to 85-90. The 18mpg in northern NV wasn't really highway, but it was alot of really straight empty terrain, and speeds that I won't talk about publicly
