I got 22 once. I also have an auto with 3.9 gears, so I'm sure that's why there is a difference.

Well, I have a 2nd gen, but I get about 26MPG on the highway (70mph+). It baffled everyone last year on the DGRR caravan how I had almost a 1/4 more tank of gas when we arrived than they did, and they were all NA.
Turbo swapped GXL with no emissions and full exhaust.

No clue, but my shit was sipping gas. Maybe you are just 'sensitive'.
Lol.

I had a black R1 that I purchased from Herblenny. When I sold it, I drove it to Michigan and got 28mpg all highway. My red FD gets around 23-25mpg on the highway normally and around 20mpg mixed(still mostly highway). If it drops down alot, start checking your fuel system.

As soon as I get off the Highway it drops to 12 to 15. Last year at DGRR I was getting about 7Mpg on the dragon.

I usually get around 14-17 driving around. If I drive it to work for a while I'll get around 19. I did get 22-23 going from here to ATL running 80-82mph a couple of weeks ago, amazed me. And for the track I'll usually get between 6-8 depending on which track.

I managed to get from Allentown, PA to Bumblef*ck, Ontario on 3/4 of a tank of gas. I'm not sure the mileage because I didn't think to look before I left. The 7 is usually pretty good on the highway, but if I really get on it I can watch the needle drop haha.

My car easily got 28mpg highway (with hills). This was with stock fuel/ignition/twins/ports, rx7.com chipped ECU, and almost every other bolt on.
I'm sure the intake, DP, MP, and catback actually helped highway mileage.

I've regularly gotten 24 to 26 via interstate on essentially stock manual car (DP, Catback K & N). Where I live it's rolling hills to flat.
Way less around town, but I've never taken the time (maybe too afraid) to check that mileage.

Best I've done is 24 mpg on the freeway, averaging 75. This is with a half-bridgeport, T-66 turbo, E6K, yadda yadda.
