rx8 tends to get better mpg with age (mileage)
driving in mid rpm (3000~5000) gets better mpg than low rpm (1000~3000)

After great consideration, I figured out the best way to save gas with the 8 is to stop driving it to work and use this instead.
Worrying about Gas mileage on the 8 is like re-arranging the deck chairs on the Titanic.

If you drive an 8 in such a way as to get the best gas mileage possible, you'll save a small amount on gas and you'll lose the benefits of driving a performance car and possibly kill the engine in the process. Doesn't sound like a good trade-off to me.
Acetone in the gas tank? It may give a boost, but I don't think I want to experiment and see what that does to an 8 over time, but if you go for it let us know.
Owning an 8 means buying a lot of gas, that's how the car is. If gas consumption is really a burden, the best solutions are to either cut out unnecessary driving or get a cheap old eco-box for the daily commute. The rotary needs to spin up and burn a lot of gas, that's life with a rotary engine.

04 models tend to get low mpg
rx8 tends to get better mpg with age (mileage)
driving in mid rpm (3000~5000) gets better mpg than low rpm (1000~3000)
This one, I'm not sure
adding acetone to fuel gives better performance and mpg
(not that I've ever done it b4)
I know for a fact that cold air intake and K&N air filter gives better performance mpg.

2. rx8 tends to get better mpg with age (mileage).. Yep my 8 runs better and gets better fuel economy with 66k mi. on the odometer.
3. adding acetone to fuel gives better performance and mpg.
(not that I've ever done it b4). Can't comment. Not me though.
4. I know for a fact that cold air intake and K&N air filter gives better performance mpg. Agree. For a number of reasons.

I was simply trying to put a reason to the difference between people who get
15-16mpg and 18~23mpg
It just seemed like such a huge difference. You don't get this big gap in any other car. I guess it's the complexities of rotary engine.
I was reading numerous posts, and all the people who were complaining 15-16mpg had two similar things.
They owned a 04, and they had low mileage.
I would love corrections on my assumptions, please comment.
PS
And no, I would not trade rx8 for anything else. I love the rotary.

Keeping the RPMs as low as possible with a rotary engine is a really, really bad idea IMHO, plus you'll be the slowest thing on the road. If you're that desperate to save on gas, you need a different car.

People who track their cars get 8-10

I think it's more about driving style than differences in the actual cars. I know that the mileage I get with my car can vary a lot depending on how I drive it, and there's a very big difference between city and highway mileage, which points to driving style as a major factor.

Best way to get Smileage;
Drive it like it was meant to be driven.
Redline it once a day
Hit the canyons on a regular basis
this makes you smile more often, therefore smiles per gallon are increased

I get 18 city 23 highway, just as advertised. I've gotten as high as 25 highway. And I redline at least once a day.
I think a lot of these difference have to do with things like plugs and coils, as well as gas quality. I'd be willing to bet that those getting less than 12 in a non-racing application have old or weakening plugs/coils.

"I drive my car like an answering machine....shift at the beep" (someone said it before but not exactly sure) I fill up when i'm down to a quarter tank and just drive it and not worry about it some tanks get better some get worse because I drive it harder....you only live once have fun while u can
