Is there any parts that i can change to get better MPG. Or just any thing i can do in General. I have a 2004 auto.tran. Rx8, every thing is stock.

 

try a basic tune up(plugs/wires/coil). using a lower viscosity oil would increase mpg too(with offset of possible lower protection)

 

The first real big question is: What is your average MPG? Most members average 15-19mpg, several down to 12-15, a few get 17-23, a very rare few get 20-24. If you are in the average member range or better, there there is really nothing else you can do.

You have the option of driving smoothly and keeping the RPMs really low, which will increase your mileage, however the rotory NEEDS the high revs to keep carbon clear and keep the 3rd fuel injectors (on above 6500rpm), from getting clogged shut. So if you drive like you want more MPG, you may just end up frying your engine.

If you are getting truly horrible MPG, then something could be wrong. If you are in the average range or better, then accepting it and enjoying the car for what it is is your best choice. If you truly can't stand the low MPG, then you made the wrong choice in a car.

 

Access Port from MM and run the fuel saving map.

 

a civic gets good MPGs

 

^yes civics get good mileage that prob only the thing to change to get much better unless ur like 8mpg or something like that! haha....

Oh and Can of worms just to inform you the 3rd set of injectors are from 6500 rpms up to fuel cutoff!

 

Thanks, 5500 was from faulty memory, I'll edit my prior post.

 

no my MPG arent that bad to sell the car and get a crapy civic lol... but just wondering what i would do i keep hearing change the air filter but i dont know which one would get me the best MPG

 

from what i have heard, i could be mistaken, but from what i have heard the BHR ignition solution can save some mpg's

 

you will NEVER be content with the gas mileage on this car, just drive it the way its supposed to be driven and live with it.

 

I'd say I'm seeing maybe 2 mpg better mileage at most. Nothing dramatic, but there's a difference. It could also be because I put new spark plugs in, or my fuel trims adjusting from the computer being reset. I'll know for sure after a few more tanks of gas.

 

2mpg is significant.. although that only amounts to maybe 30 more miles per tank.. but there you have it. 2mpg on a car that averages 17mpg.. not bad.

2mpg on a car that averages 40mpg wouldn't be significant.

 

Judging by filling up today, It's only 1 mpg better then usual, but I was also driving harder then I normally do to try and use more gas.

It's not a mod to get because you want to save gas. It's a mod to get so you never have to worry about your coils going bad ever again.

 

No way.....

 

yeah the BHR could help some but as said above not a gas saving mod it just so happens that it gets a better burn on the fuel so u see some outcome....Air filter is a good start if stock intake a K&N is probably the best run u about 50 or 60 bucks but it's still not going to help more than maybe 1mpg....also make sure all ur tires are properly inflated and that u dont' have any brakes draggin(yes have seen it)

 

Oh Can of worms we all have those moments haha!

 

Way. There is a difference. Not enough to market it as a fuel saving mod though, nor would I recommend it for such reasons. I take it to mean that it's burning what's there more efficiently, resulting in you being able to go a bit farther on a tank because less gets blown out the tailpipe unburned. You'd need an access port to lean out the fuel mixture if you want to see proper gas savings. There's no way a set of coils is going to let less gas into the engine.

It'd be way more economical to over-inflate your tires to save gas. Air is free.

 

^ha yeah air is free!!!

 

I got excellent millage when my trans broke and I got a 3 as a loaner from the dealership....

Other than that... I agree with the posts above; you really cant squeeze any significant mpg gains out of the car without doing anything extreme to the car... rotaries are just inefficient

 

I herd of some brake rotors that drop 25lbs from the front end I suppose that dropping some weight from the car and maybe yourself would help out along with the intake. And just maybe try not haul but everywhere (I know it’s hard to drive like a civilized person in the car) and plan things like for example don’t just race up to every stop light maybe just maybe take you foot of the pedal ahead of time just a thought though.

 

very true dropping any weight will help too so start hitting the gym haha
