Worst Gas mileage observed
 

What has been the worst gas mileage you have observed with your new RX8?

I am getting 13 MPG.

Five fills so far. Worst: 14.78mpg; best: 17.99; avg: 16.45

My mileage actually got worse after the break-in period, primarily because I've been hoofing it everywhere. :D No doubt it will come back up again when (if) I settle back into a more leisurely driving style.

Worst was at an Evolution driving school we averaged 8 MPG. That included driving around town with some freeway as well.

It sounds like only people driving RX-8s in 6 speed manual are getting the shitty mileage.

How about you guys who drive the car in automatic?

Same shitty mileage as what everyone else is saying on here?

autos get bad gas mileage too. I average 13 to 16 mpg

Around...25-26 MPG...oh wait that's in the EVO......:p

Hey if your going to mock the 8's mileage, make sure to use your cars real name. Lancer!

Untwist those panties, I'm being funny.

Well since the Lancer was derived from the EVO, not the other way around..I think my description is just fine. :p

*blink* To the best of my knowledge, the name Lancer Evolution VIII comes from the fact that this is the eighth rally-targeted evolution of the original Lancer. Methinks you have it bass-ackwards. :)

ask it mitsubishi.

Or better yet, Mitsubishi Japan's own motorsport history site. :)

WE WILL NOW RETURN YOU TO THE SUBJECT OF THE THREAD:

The worst: 18.85, the best 20.5.

I don't know why others are getting worse. I stick the pedal all the time and take it to red line frequently.

I finally heard the "tone" last night. The radio has been too loud previously.

thank you puppy1... back to topic

Worst is 19.4, but only three tanks so far. I thought I was a bit heavy footed as well, but I guess not. Try shifting above second once in awhile :)

is it possible that youve been cruising in 4th instead of 6th?

ive been getting really good mileage lately (havent been calculating lately though, just been noticing that id have been driving for about 100miles and have more or less a quater of a tank)

however, since ivepassed break in, ive been getting horrible mileage, from redlining it so often, but ive stopped that mostly...

4 fills so far, the first three averaged 215 miles per fill (taking it to well beyond the empty warning light each time)...so thats about 14~15MPG during the break-in period. The last tankfill, which was after the break-in period and a very heavy foot, only yielded me 176 miles, which brings me to 11~12 MPG. By 'very heavy foot' I mean that I drive the car the way it was meant to be driven, same way with the 7 I own....that being shifts between 7500 and redline (or beyond), and cruising on city and highway roads between 5 and 6k.

I've been doing alot of highway driving and getting about 290-320 miles per tank.

How about we ask some more people who know how to drive for mileage instead of asking the people who don't give a shit about fuel conservation.

There is no need to redline the engine all the time. It's absurd.

absurd to people that want to drive their cars like my grandma....no, scratch that, my grandma would want to redline this car and this engine as well....probably take her for a spin later on today.....

anyone that expected to get good mileage from this car was mis-informed from the get go....a rotary is inherently flawed in that department...so be it....just drive your car the way it's supposed to be driven and stop tryin to baby it.......I have 150k+ miles on my 83 and it's still kickin, drove it the same way....replaced the seals once.

Hey without offense, but I can't resist it: Lancer('s) Evolution, does that ring a bell?

Laid on a different way: the Lancer Evolved into it.

I got a bit above 22 mpg today , all highway at 75 mph. i cannot see it going any better unless i drive it at 60 mpg which i won't !

You got the auto or the stick?

Ok... My 13 mpg is bad. I drive between conservative and aggressive. Shifting around 5000 RPM average with shifts at 6500 or as low as 4000. Maybe an occasional 7000. What is going on here.


Lets see...


People driving very aggresively, between 6000 and redline get around 12 mpg.

People driving conservatively are getting around 21 mpg.

I should get around 16, no?

I just hit 1000 miles on the car. My worst tank was 17.4 mpg; best so far was 19.7 mpg.

I've been using 5th & 6th gear more now while cruising; which has helped. I use to try to keep the revs above 3000 when cruising. But now, I'll keep it between 2000 - 2500 (obviously downshifting to accelerate).

I can see how people may get 16 mpg...but 13??? Seems like you'd have to cruise in 3rd gear going 65-70 mph to do that. :confused:

That is the funny thing. On highway, I only cruise in 6th, take it down to 5th to pass. All other times, I'm crusing around 3000-4000, sometimes as low as 2500.

Anybody know what I should do?

I talked to Mazda and they gave me the: "oh...it's the weather. It's too humid to get good gas mileage, plus the use of the air conditioning is bringing it down".

I'm baffled!!!!!!!!!!!!!

theres three possibilities, and one far fetched one

1: your not shifting as you say you are
2: your calculations are wrong
3: your car is leaking gass


and 4

is it possible that only one of the rotors is spinning?
nope...nm, cause then youd have to be way higher (rpm-wise) to have highway speeds

edit:
as a side note, are you SURE youre in 6th and not 4th?

My three fillups, highest grade 93 octane, 6 spd:

DATE MILES GAL MPG
7/26/2003 233.5 12.901 18.099
8/3/2003 253.0 12.777 19.801
8/14/2003 251.2 13.740 18.282

I can't figure what I'm doing wrong, I try to go fast and accelerate alot (traffic allowing), but I can't get my mileage down with the rest of you!

I want to know just how are you guys drive to get so lousy mileage. I'm not being (too) sarcastic, but I not sure how other than getting arrested each and every time I go out I could get the mpg's many of you are observing?

jonalan - I don't follow what your reasoning is and what you're trying to accomplish? Why would you be '...using 5th and 6th more "now"'? What is "now"?

Why would you **NOT** be using the top gear(s) normally all the time? If you drive an automatic, do you take it out of drive and run in 3rd or 4th, not top gear?

The rotary engine is exceedingly tolerant of low speed low rpm running, little if any bucking common to other engines, smooth power, etc.

I would always shift to the highest gear possible, barring a need for acceleration exceeding the gear I'm in. What could be the possible advantage to doing otherwise... except buring more gas and wear and tear on the gearbox? You are getting decent mileage like mine, still you could get better I believe. We should start a thread "Who can get the BEST MPG". The suckiest is way to easy.

If the majority are 'keeping the revs up" for some unknown reason, I can understand why you are all reporting suck sucky mileage... :confused:

We've had 4 Fill-ups thus far.

Worst = 20.0 MPG (all city driving)
Best = 23.5 MPG (25/75 city/hwy)

Right on as projected by the EPA rating.

Yeah I can't see getting 13 without getting arrested. Today I pulled out of the parking lot at work, saw a car coming so I floored, WHOA NELLY. I use to do this in my tiburon, but would be at the end of the street before hitting 60km/h, I hit 60K in like 50 meters it was NUTS, then I went quickly through the gears to 5th.

I cruise in 6th everywhere I go.

my first, worst, and only tank so far resulted in 15mpg... I attribute most of it to spending a good 2 hours starting and stopping to learn how to drive stick :p


Filled up yesterday, been driving like a complete granny (1500 - 3000 rpms), put 80 miles on so far and by the looks of it I'm getting over 20mpg in mostly city driving :cool: ... hopefully after this tank I will be able to go to that other thread and brag about my great mpg :p

1. no- i'm not a liar
2. I'm not an idiot, I go to one of the top 12 universities in the nation for business
3. I'm not an idiot, I would see it

edit-

I'm not stupid, I know what gear I'm in.

Please don't post replies if your going to say unintelligent things

Are you guys positive the automatics get the same bad mileage?

I was thinking that the computer on the ATX RX-8 would put the car into 5th gear as soon as possible like on other cars with triptonic.

Are there any other automatic owners out there that confirm this low mileage problem on their 8s too?

*********OFF TOPIC FOR ONE MOMENT*****************

Hehe..well yes and no..the US Lancer was from my understanding modeled off of the JDm EVO VII. Of course, all of the EVO models are based off the base Lancer platforms. They are so modified from that base that its really a stretch to call them "a souped-up Lancer". There is a reason its nearly double the price of the Lancer ES.

As long as EVO and Tope Gear Magazine still call it an EVO, I will too. :)


**********NOW BACK TO OUR ORIGINAL RANTING*********

OK, Lancer-guy, just for your information: the Mitsubishi Lancer did already exist as an economy model back in the eighties in Europe (probably in Japan too). Now, I don't know the US history of the Lancer nameplate but I'm almost certain that there was no souped-up version of that car (aka "EVO") back then. Someone correct me if I'm wrong... but if I'm not, then yes, you got this all backwards.

See my previous post (right above yours). The US Lancer was based off of the JDM EVO VII. Of course, all of the EVOs have been based off of base Lancers. However, keep in mind even the base Lancer design is made to allow an Evolution or EVO model to be produced. For example, I heard they wanted to make the cabin bigger on the base Lancer, but didn't because it would not be compatible with an EVO version.

Personally, I was hoping the next EVO would be based off of the Mitsubisho Colt (not available in the US) since it is smaller and lighter. Unfortunately, it doesn't look like this will happen as it seems like MItsubishi is sticking with the Lancer EVO as its WRC entry. I think a Colt EVO would have been better in the WRC as the smaller cars have dominated the past 2 years (i.e. Peugot 206 and Citroen).

Anyway, I don't want to further hijack this thread, so if you want to continue this please create a new one.

For example, you don't need 6th gear when you're going 35mph.

When I first got the car ("then"), I would try to keep the revs around 3000 (maybe 4th gear going 35). Now ("now"), i will use 5th gear when going 35, and the revs may be between 2000-2500.

1: never said you are lying, could have been MISTAKEN
2: if you think that means youre intelligent, you obviously are, indeed, an idiot
3: you could be parked on gravel or dirt or what not and not see it, so dont whine at me, i dont know where you park, and dont know how observant you are, it could be gas and you thinking its condensation, if there is anything there at all

4:if you are pulling straight down from 5th you will be in 4th, this has happened to people on this forum, it could well be happening to you

I agree with you on point number 2, P00.

However, on point number 4, if you pull straight down from 5th, you will be in 6th gear. 4th gear would be below 3rd.

Well, I guess if you pulled down from 5th without guiding the shifter it would naturally snap over to the left and slot into 4th. I've seen "cool dudes" try to shift all slick like that and screw it up and cause their engiens to whine in a most unbecoming manner.

Ok, you know what your talking about.




So, by your unintelligent logic, I could go ahead and say that people attending Yale, Harvard, and Princeton aren't necessarily Intelligent.


Do you think these top Universities and other top Universities accept students who can't complete simple arithmitic, such as division? There is a thing called standardized testing, and on this testing there are math questions. In these math questions are simple arithmetic and more advanced arithmetic. A person must be able to complete the simple arithmetic to complete the questions correctly.


Put 2 and 2 together genious.

I go to a top University, I did well on standardized tests, because I am intelligent and I know simple arithmetic. That is why I go to a top University.

All it takes to calculate gas mileage is simple arithmetic. I know I can handle it, I have proven it. Can you handle it? Have you proved it?


People do make mistakes. I, or anyone else, can make a mistake dividing. But for me to make a mistake on several calculations over several tanks of gas is impossible.
Who cares anyway, you say stupid things.



So saying that my calculations may be wrong is, in itself, a stupid thing to even suggest.

I can confirm my 8 is auto and I am gettin 13 to 16mpg if I'm lucky. I haven't had a speeding ticket in years so its not becuase I drive really fast or anything

exactly, though 4th is directly beneath 3rd and "diagonally accross" from 5th (meaning it is obtusely aligned) if you pull straight down, due to the angulation of you arm, you will be causing it to slide into 4th, to put it into 6th you have to push to the side a little and then down, as youve probably noticed

That's terrible. The EPA ratings must be way off. BUt, it seems that some people are getting the estimated MPG, and some are getting much worse, even without being all that aggressive.

thats cause its a frekin old time 4 speed, at 60 mph you probably have around 5 grand on the tach

WOW! Too much to comment on here but this takes the cake.

Man am I glad I'm just a dummy. Is this what our "top ten" Univerties are made of?

thats why i didnt even bother to respond lol

its pretty funny really, also incredibly sad in a way

Geez this is getting sad. Anyone (RX8 owners or not) who speaks up about RX-8 deficiencies gets bashed on. These guys just stated their poor gas milage experience with the RX-8 and the next thing you know, we got personal judgments, name calling and every other person is a liar. Calm down people~ If you guys know how EPA ratings are established, then maybe we'll all know why it's hard to obtain the same numbers under real world conditions.

From what I heard (which could be wrong)

EPA Highway = running the car in top gear at 65mph continuously on cruise control around a oval track.

EPA City = running the car in top gear at 45mph with some stops here and there. I wouldn't exactly call it EPA City, probably call it EPA country side.

Now unless you guys drive your cars like a train, it'll be very hard to achieve those EPA estimated numbers.

STILL waiting for another person with an RX-8 in automatic to chime in about their gas mileage.

In other great and wonderful news, gas prices have gone up again..and we owe the blackout a partial thanks for the increase.

Premium gas is going to be pricey as hell the next few weeks. Gas mileage is not something to be overlooked with this car.

yeah premium in SF Bay Area CA $2.39. Cost me >$30 to fill up. Least I don't have an SUV....

Milage? How about GAS Type?
 

Does the type of gas change the milage factor at all? I just bought the Auto, and I haven't tested out the milage with different gas types.

I thought this also might help answer the worst to the best mileage issues.
