Hi all. Seems like my rx8 isnt getting as good of fuel mileage as i thought. on a full tank ill get around 200-230 miles. is this normal? what kind of mileage should i be getting on a full tank? seems like my gauge drops fast.
Also can you use fuel injector cleaners on the engine? i wasnt sure because it was a rotary. or anything to do thats not too costly for better mileage if mine is bad?
it is an 04 with 70k miles.
thanks!

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.
So if you can't get this mileage, start poking around for what is wrong.
