Hey, I own an 87 RX7 GXL and I hope that someone here can answer my question or at least make a few suggestions. My car is getting horrible gas mileage...I would like to know about how much its suppose to be getting or if there is something wrong with my car?

I think 17 to 18 is average for a healthy engine. If it is lower check your plugs, wires, fuel filter and air filter. You may want to look into a grounding kit of some sort, after so many years the grounds get corroded which can cause a host of problems.

I get 230-240 per talk fill about 12 or 13 gal

in my 80LS which has a 14.5 gallon tank, i get about 16.5 to 18 mpg.

I was getting around 17-18 when I first got my car. However, after removing my cats I started getting amazingly good gas mileage. I want to say I get at least 22-23 city, and problably around 30 highway. It's great. And I redline my car almost daily, and in daily driving 5k rpm is pretty standard. 230 mile tanks. It's great.

I just got 26.5 on a run down to Columbus and back.

Mine was/is getting horrible mileage also, about 4L/Km (do the math yankee's :p ). I changed all the plugs, wires, fule filter (under hood, not in tank), o2 sensor, all fluids, and did the timing. Still getting horrible mileage, I think I've narrowed it down to a faulty Pressure sensor though. Voltage reading at the sensor is pretty whacked... Making my o2 sensor read rich 100% of the time.

I did the math, I hope that's a typo... you said 4 liters per kilometer.... Google says:
4 (liters per kilometer) = 0.588036461 miles per gallon

Now that's **** mileage.

But, if you meant the inverse, google says:
4 kilometers per liter = 9.40858337 miles per gallon

I really hope you made a typo.

Next time, you do the math first

I got 21 mpg in my '73 RX2 that has an '85 12A and the RX2 carb. It was during a highway road trip, 190 miles each way, between eastern and western Washington. The RX2 is an automatic.
