Combustion engines are most efficient at constant speed constant load.

So cruise control with rpm's under 3.5k rpms will net you 30+ mpg pretty easily. If I take a shitty way to work I'll get <25 mpg, if I take the route with smooth flowing traffic I'll be well over 25 mpg, cruising on the freeway at 75 mph will get me 32 mpg easy. This is of course assuming you're not redlining all your shifts.

If you're driving in a city and stopping every block getting less than 25 mpg is expected, see the window sticker.

I normally get about 28mpg on average (Limited 6MT) but I've been driving less since my carpool buddy bought a WRX, so when I DO drive now, I tend to drive a bit more aggressively. My last tank was only about 25.1mpg.

I drive pretty aggressively most of the time and I live in the city so lots of traffic to get in and out, but also a fair bit of highway on the way to and from the city. Typical speed on the hwy when not stuck in stop and go is 75mph (120km/h).

My car says 7.3L/100kms for the lifetime avg (5500kms/3500 miles), which is about 31-32 US mpg. I have not backed up these numbers.

6MT, lowered on Sportlines with 18x8.5/18x9.5 rims and 225F/245R Michelin Pilot Super Sports.

I have averaged 30-31 weekly and my commute includes 30 miles of stop and go traffic each way on the freeway. The best I have achieved thus far is driving back home from Reno, NV, where I got 35+.

[Trashed675]

I usually AVERAGE 30-33. HWY mileage is usually around 32-35. Highest i've seen for about half a tank was 36(alot of 55-60mph roads).

Since i got Visconti tuned, HWY mileage seems to have bumped up to about 33-36. I've only got about one tank on the tune though, and i've been "testing" it. I'm thinking 38-39 should be doable in the right situation.

I was also extremely pleased with the mileage of this car since i bought it expecting only 30.

I guess I just enjoy driving hard a bit too much. I usually average between about 20 - 22 mpg per tank in mine.

I'm at 31mpg with my AVO turbo kit installed.... and that is mostly city driving.

Nope.

405 in West LA, 6 lanes each side, still stop and go every day.

24 mpg all city on my auto brz limited. I like shifting at redline too much after every turn

[zoomzoomers]

I have a Limited 6AT and I get a wide variance in my mpg's. On strictly hwy's I can easily get 34 + , but as soon as I get off the hwy and onto surface streets that will go way down into the mid 20's and stay there. And that's all driving very conservatively. So go figure...

[jeebus]

My average over the last 18k miles is 29MPG. That includes quite a few AutoX runs and I don't drive like a weeny on the street either.

There are a LOT of FT86 owners tracking consumption with Fuelly. It's almost an exact number of FRS and BRZ owners. Other sports cars don't have nearly this much data. Very cool!

With my bolt-on mods + tune, I get 32-34 mpg cruising 70-80mph on my trips out of state, depending on how flat the highways are. The mods/tune make it easier to cruise at that speed with less effort.

On my daily work commute (~75% hwy), I get 29-31 mpg, depending on how much traffic I hit.

With E85, I get anywhere from 21 to 25 mpg on my work commute.
Not that great, but it's also $0.75 – $1.10 less than premium gas too.

Ouch, I'm low on that list. 22MPG tanks are pretty standard for me with the city and rush hour driving I do combined with my prodigious use of the throttle. The highway can vary from 28-35MPG tanks.
