240 miles per tank, good quality 87 octane (low test) is about $1.89/gal. I'm getting about 17-18 mpg, but that's with an identified slow leak on my front injector - have to get that apart next weekend and reseal (what a PITA,...).

Gas is $2.25 here for premium and who wouldn't buy premium for their rotary i swear...If you loved you car you would put premium in itburns better and increases engine life. But I average about 180 on about 1/2 or so a tank

Before I moved close to work, I got about 250mpg, driving about 30 miles a day. Now I'm lucky if I get 200; more like 175 on average. My trip to and from work is about 3 miles, spending most of my time in the car at stop lights. Gas is ~$2.15.
As far as premium gas goes, why would I waste my money? My car has 275,000 miles on it and seems to run better on the cheap stuff.

Where in the world can you get one gallon of 87 octane for $1.39??? That was two years ago!!!!
Heck Yes!

Lets see here I get (depending on how hard I drive it) about 450 km ~ 275 miles. On low test because we are paying any where from $0.76-$0.89 per litre.
Now bare in mind that 1 USGalon = 3.79 Litres so that makes fuel $2.88-$3.37 per USGalon.
Oh and then add another 30% on to that for exchange rate...
That makes it $3.75-$4.38USD per USGalon.
So don't feel so bad when you are paying $1.89 - $2.00 per Galon
I don't drive my RX-7 to work (120 miles round trip)

Hey, Nector-Rivera - run a quick search on "Fuel-Octane" and learn something about the rotary engine design NOT requiring high octane fuels to maintain best fuel economy and longevity!
The short of it is that the rotary engine, by design, is fairly knock insensitive. The relatively slow compression cycle of the engine, followed by the long flamefront during ignition helps to retard detonation unless under turbocharging or extremely lean conditions. This means that money spent on high octane fuels is wasted on a rotary engine. To make a point, during the IMSA racing days, the rotary powered teams used PUMP-GAS, not readily available racing fuels to win that series - that's a testament to the truth of the conversations about this.
Fuel octane boosters were designed in the 1930's and 1940's specifically for piston engines to DECREASE the fuel's tendency to burn when under compression. In other words, the high octane additives were introduced to combat higher compression piston engines which were developing more and more horsepower. Along comes the rotary and blows all that theory to shame. Any unburned fuel that doesn't get ignited will be ejected into your exhaust system to be burned in your catalyst, increasing the risks of a clogged cat and poor emissions.
Save some bucks and go low-test - your mileage and performance may actually increase due to more efficient burn rate. JMTC, YMMV (literally!),
P.S. - pass the popcorn!
