I read on here that the car is supposed to get better mileage after 2000 miles. OnThursday I drove the car all the way to empty so that I could have a freshtank after getting the car up to 2000 miles and then I filled the tank up fresh. I reset the trip meter tokeeptrack of my miles. You guys remember I have an automatic not manual and I only do city driving no highway. Well Now its late Saturday night and I have driven156 miles on this tank from Thursday to now and my tank is already down to 1/4 full! Its still the same crappy mileage that I wasgetting before 2000 miles man. Im already at 2200 miles and Im not even getting 15mpg. Somethingsvery wrong here. Its all city driving and I drove it hard only twice since Thursday to beat two redlights. Im making sure the car is always in 4th gear but I guess nothing is helping here. Im not very happy about this guys! Should I take my car in to Mazda or arethere other people here w/more than 2000 miles that sitll get bad mileage like me? I thought this was going to finally go away!!

Seems like there's too many variables for us to figure out exactly what's going on. I am concluding each car has a "personality" of its own as no two seem to behave alike. Mine did improve after 2K from ~ 15 mpg to 17-18. Many people have been in the low 20's all along no matter what they do. Go figger. This is my #1 gripe about the car. The only reason I kept it despite being eligible to return it is I believe someday it'll be fixed. I think Mazda and maybe some aftermarket folks will find a way to improve mpg while not giving up too much power and still meet EPA specs. I don't know any of this for a fact but I do believe it.

this is not good. maybe your ecu was not reprogrammed correctly at the port. :mad:

you could have dealer check it out

I've had my RX8 with AT since Aug 23. With 50/50 city/hiway I've been getting about 21mpg.

I now have 1500+ miles on it. I took a 303 miles drive which took 12.5 gallons to fill. That works out to 24+ mpg. It was 95% hiway driving with speeds mostly between 50 and 60mph.

Since the AT is supposed to get 18 to 25mpg, my RX8 seems to be right in there.

I've noticed many postings (in this and other forums) where people are only getting 13 to 15mpg. Either they are heavy footed or their RX8 should be taken to the dealer.

Hogwash. Dealers don't have a solution for this issue. Many people have contacted their dealers AND MNAO. Its already been established on this very forum that its NOT people's driving habits. Do your homework before making blanket statements.

I am over 2k & my mileage remains a crappy 12-13 MPG. If I am all highway, I can stretch out a mindbogglin 15ish MPG figure. As you might have guessed, my car is going back. I remain bullish on all the other outstanding qualities of the 8, & will gleefully buy another, brand new RX-8, once its been established Mazda has got their sheet together.

thank you for setting the record straight, astrlsfr. You took the words right out of my mouth. With all the raw data we've seen establishing no discernable pattern I think one thing we've shown is that driving habits have only a small effect on gas mileage. There is still some unknown variable, which I attribute to something in the car, having the greatest influence on gas mileage. I suspect Mazda did some ECU reprogamming in haste and didn't have time to either standardize it nor assess all the impacts of their reprogram. I wonder if we need to try and drag the EPA into this for those deviating dramatically from the EPA estimates.

Sorry to hear you're sending your 8 back. Such is life. With over 2,000 miles on yours, you've likely filled up about 8 times, using a (high for you) 15mpg average.

Can you share with us the tank by tank numbers: You know, like this, so we can puzzle over it? Here are mine, for example, after picking it up with a full tank on the 18-JUL, about the same day you did.

DATE MILES GAL MPG
26-Jul 233.5 12.901 18.10
3-Aug 253 12.777 19.80
14-Aug 251.2 13.74 18.28
25-Aug 245.8 13.7 17.94
6-Sep 243 13.89 17.49
11-Sep 150 8.104 18.52
22-Sep 235.8 13.35 17.66
3-Oct 242 13.4 18.06

overall 18.23 mpg @ 1854 miles

I'm getting 15 MPG(13 MPG once but that was because i was helping a friend with stick that envolved a lot of idleing), but i have a very heavy foot shifting between 6k and 8k.

Just passed 1k on the odo. This next tank i'm gonna take it easy and see how much i can get out of the tank.

dude i get like 160mpg...what is that like 11? i live in a small city so lots of lights, and stops...most i drive consecitively is like 10miles, and thats to school..also the temp is usually like at 100F daily, i live in laredo texas..small city. also i use to get 160mpg, and after 2000miles i now get around 180

I didnt do alot of driving in the Rx8 today but I know my tank is going to be at empty when the tripmeter reaches 200 miles tomorrow afternoon. That tank is not even gonna be 14mpg guys. I looked at my dipstick today and the oil is not on full anymore its in the middle. Maybe I should try toget my oil changed to see if that helps my mileage??? Thatsounds stupid but amybe it will work

u think since i live in a very small town..it affects me more? since all the lights?

If you look at the posts here the people compaining of low milleage are all from Hot climates. Maybe they reprogramed the ECU and it over fuels the car in the heat to cool the engine. Try putting 35 psi in the tires it will help.

I just passed 6000 miles and I'm getting roughly 19 mpg. Like many people have said before, it varies from case to case. Elevation, temperature, humidity, how you drive it, etc...

So what do people think of the '8 in Laredo. They must think yer some kinda hippy escaped californian or something. :) But I think you mean mpt (miles per tank) not mpg unless you've made some kinda hybrid car.

Sorry to hear you're sending your 8 back. Such is life. With over 2,000 miles on yours, you've likely filled up about 8 times, using a (high for you) 15mpg average.

Hey Spin9K. I've got a 1SP 6MT and my mileage is almost exactly what you're getting. My average is 18.5 to 19 MPG with mixed city/highway driving. If I leadfoot the tank, it drops to around 17 MPG. I'm taking a long highway road trip (Orlando to Atlanta) in another week and will track the mileage all the way. I'm hoping to get in the low 20's averaging 75 MPH on the highway. We'll see.

Spin9K, can you please share with us math-challenged folk how you figure out those numbers exactly? I've only filled up once, and here is the way I did it: When the light came on at 228 miles, I figured there were two gallons remaining. Thus 228/13.9 = 16.4 MPG. Thanks.

Rgr that - I'd been getting average of 17 mpg here in FL. The first day it got cold (below 60F) for my morning drive, I managed a 19.8 mpg! Unfirtunately, I've been driving during the warmer times since - and yes, I rev the crap out of this car!

The light is not that accurate. It could come on with 1 or 4 gallons left, depending on the car, road level, etc.

When you go to the station, note how many gallons of fuel it took for the tank to fill up and use that number.

astrlsrfr:

re your "hogwash" response...

I did a little "homework" as you stated. I'm finding that many people who are getting poor gas mileage are "cruising" at 5-6k rpm.

I've been getting my good mileage (with my loaded auto trans) by keeping the speed between 50 and 60 (as per the speed limit signs) which puts the rmp at about 2500.

Do the math - if you cruise at 5000rpm your engine is going to use more gas than mine when it cruises at 2500.

With 600 miles on the odo I'm getting 15mpg. Pretty bad for such a small car, but I keep vigil that it will improve...

Also, out of curiosity when does everyone's empty light come on??? Mine turns on when I get to a quarter tank which is very conservative! :confused:

what astrlsrfr (and many others) are trying to do here is stay away from anecdotal evidence that can mislead. Like, I drive with my headlights on and I get good mileage, therefore if everyone drives with headlights on then everyone will get good mileage. There is a lot of this nonsense going on here and is distracting us from seeing the real problem.

I appreciate you taking the time to research it but I think we still haven't gotten to the bottom of it. As you say, " many people who are getting poor gas mileage are "cruising" at 5-6k rpm." This is true. However, there are many people cruising at greater than 5K who are getting good gas mileage. And there are people cruising at 3K who are getting crappy gas mileage (me, for instance.)

This is what I meant in my earlier post that "we've seen no discernable pattern (but) one thing we've shown is that driving habits have only a small effect on gas mileage." Its very puzzling, we see conflicting data, and I don't think a single, underlying cause like RPMs has yet been found. I believe our cars are programmed differently and no matter what we do, we're doomed to either good or gas mileage. This is strictly my opinion based on anecdotal evidence (which I said I'm trying to avoid) but I see no patterns or trends that can support any other conclusion. This opinion goes back to the days of the first shipments in July that were mysteriously held at the Port of Entry for some unknown reason. I think reprogramming was done at that time, in haste, to meet EPA requirements and now we've got a variety of ECU programs among the RX-8 fleet.

8-wannabe:

You are correct - I stand down.

If it is the ECU it seems that something could be done about it at the dealer sooner or later- yes?

do you guys anticipate that Mazda will do somethin about this mileage problem? maybe workout some patches to the ECU program so we get better mileage.. I've read many of the posts, but im on the same boat, im getting abaout 350~380km per tank :(

Here is my mpg log (http://www.5cats.org/rx8/_RX8_log.htm).
For comparison, I also drive a 4.0L M/T 1993 Ford Ranger just as hard/conservative as the RX8, same routes, times -- hey, old habits and all -- and got 15.97 mpg on the last tank.
-jd.

I seem to have ended up with an 'in the middle' car for the mpg. I know some people are getting 20+ no matter what they do, and others can't get above 15 mpg despite driving like an old, sick grannie. Myself I drive conservatively. I shift between 3500 and 4000 rpm, and generally cruise around 2500-3000 rpm. Getting about 16-18 mpg regardless. My current tank will be very telling. Lots of highway driving between 70-80 mph (3500-4000 rpm). So far it isn't looking too promising (120 miles and I'm one notch above half-way). Won't know for sure til I get to the gas station and fill up though. I have 1200 miles on the car for the record.

O.R.A. had it right, the light is useless as a measuring device to figure MPG figues.

Here's is what to do - START doing this the next time you fill up.

1) Try to TOP OFF your gas tank manually with the pump without overflowing. WHY? Because auto-shutoffs don't all stop at the same fill level, even the same pump from one fill to the next.

2) Reset the trip odomoter & NOT THIS FIRST TIME, BUT EVERY TIME THEREAFTER save each slip and WRITE the TRIP ODOMETER mileage on it, then reset to '0' miles.

3) Divide the number of miles driven (trip odometer reading you wrote on the slip) by the gallons as shown on the slip. Use a caculator and USE the tens and hundredths of a gallon reading if shown.

4) Repeat 1-3 to see your TRUE MPG for each tankfull.

NOW for the OVERALL MPG OVER MANY TANKS WORTH OF GAS. As you accumulate slips, save them somewhere. (I enter them in a spreadsheet, but paper and pencil will do)

1) Keep a running total of miles driven. Each time, add the next TRIP ODOMETER reading to the last total miles you have. (NOTE - DON'T use that first slip in this total!)

2) Keep a running total of gallons driven. Each time, add the next gas station gallons reading to the last total gallons you have. (NOTE - DON'T use that first slip in this total!)

3) Divide the TOTAL MILES / TOTAL GALLONS to get the AVERAGE MPG.

The longer you keep records like this, the more accurate your MPG reading for the car will get. Any small errors will get averaged out. And although some of you may think this all too simple, others may not. Math can be a challenge, hopes this helps.

Sorry to dump on an optimistic theory, B-Nez, but the idea that cold weather will help mileage for cars from hot-weather areas isn't working for me. I got bad mileage in Washington, DC heat and humidity. Now we're having delightful fall weather (65 highs, 40-50 lows) and I'm working on one of my worst tankfuls. At 1,900 miles.
Mitch

New york city here- so not hot weather- and poor milage as well.

anything from 11 city to 15-16 highway

Mine's got about 1000 miles on the clock so I've filled it up about 4 times now - I've consistently got ~250 per tank which works out at 18mpg. The kind of driving I do is mostly freeway at betwen 80-85 mph sometimes a little faster but rarely slower. A very little bit of town driving is done.

I'm pretty sure if I was to drop it below 3,750 rpm crusing (which is about 70-75 mph) I would increase my mpg to over 20. If I drove at optimum "highway" speeds (which is 55 mph I believe) I would probably get the posted 24 mpg easily.

From what I've read the engine opens up an extra port at 3750 and I suspect it's this that guzzles the fuel.

I have a suggestion. Why don't we compare information.

Transmission/car type type: 6 sp GT

Highest average speed in our daily commute = 50 mph

Average distance traveled 1 way = 17 miles

Average time taken = 35 minutes (accounts for stop and go)

Octane of gas used and brand (if known) = 87 oct Penn (Sam's)

Ambient temp during commutes 76/91 F

Average mileage based on miles driven by gallons used = 17.7 mpg city. I usually go to about 240 miles to tank and calcualate the mileage it is from 17 - 18 (varies week to week)



We should be able to figure out something. Besides the geographical and environmental differences, there are our driving habits to consider.

My Mileage Record is below, mine seems to be middle of the road, averaging 17 around town, and 20 highway. Made a nice long roadtrip to california, and the heat there made little difference on the mileage over my around town driving up hear in washington.

My overall average, with about 80% highway, is 19.34 mpg

However, I don't believe "highway" is very meaningful. I think it's officially 55 mph or something very slow. If you drive at 80 most of the time the mpg will vbe significantly lower. This is of course obvious but I do think we need to factor in what you *really* drive on the highway not just some fictional value used by the car industry. What was your average "highway"?

Ok, here's something weird for you guys- I get my best mileage on the highway driving over 70. For example, drove to Maryland this past weekend on 95, going between 75-85 the entire way. Got 24 mpg. Between 55-65 I get closer to 20 mpg.

I get crappy mileage when I drive in the city in stop and go- my personal worst so far has been about 14.9, and that was last week in all stop and go traffic.

this is to 8_wannabe

ppl. in laredo LOVE the car, there is about 6 of them here so far, they stop and look at every light. they can't get enough of its style ..it makes me feel...hmmm :D

Hot climate here, and I'm getting between 18.3 and 19.7MPG every tank (9 recorded so far), no matter the city/hwy ratio. Car currently has 3300 miles. I don't believe anything magical happens at 2000 miles. I do believe my car gets slightly better mileage (<1MPG) with 89 octane than with 93.

Good idea.
I put your data in an Excel sheet. Added mine and attach it here.
Unfortunately this system doesn't allow XLS files :-( I had to ZIP it.
The next person can download it, add his/her row and attach it again? Do you guys think that'll work?

-Peter

i think im getting off like a bandit... im getting 18-20 and my car lives at 6k rpms :D

A lot of it depends on your time at idle. I've noticed when I sit idle at lights for a long time in traffic my car gets bored and starts sipping gasoline like lemonade. I drive the long route to work in the mornings now because I think it uses less gas to go 5.0 miles around and be moving almost the entire time, than to go 3.0 miles and be sitting idle for longer.

nice graph fuzzi

Guys I guessI was wrong. That tank made it to almost 245 miles before I got to the gas station. I drove it for atleast 20 miles with the empty light on and the air conditioning and radio off and windows down. I guessthat means my mileage really eneded up being like 17mpg. Not really sure. I know that I drove like 6 miles with the gasnozzle sitting below the empty line. I really thought I was going to runout and breakdown before I got tothe station. I think when the emptylight comes on you stillhave 2 gallons left to go which is pretty stupid. When it came on for me on this tank I only had 215 miles on the tripmeter and it made it to almost another 30. I bet you that if I didnt drive very slow and with allthe stuff turned off I wouldnt have made it there. I cant believe this. I hate driving the Rx8 like this just to get this kindof mileage.

my "Highway" was my typical Road-trip style driving... Long streches of about 80-95 mph, then a stop at a rest stop and/or gas station every once in a while... some short stints over 100, but that is only at times where coming over a hill into a beautiful valley, with a clear view of what's ahead of me... just begs my foot to the floor.. :-) I thikn the biggest impact on the cars mileage, like most cars, is accelleration. Which makes since physics wise also.

I just filled up anothertank last night. I want you guys toknow that I have figured out my Rx8 tank always has 60 miles on the tripmeter by the time the gasnozzle gets to the 3/4 mark. This was the samething I got on the last tank 60 at 3/4 full. Is this thesame for you guys too?? That is with only city driving btw. I guess this means that if I keep going atthis rate then240 city miles a tank isgoing to be what Im always going to get. Wait but for my mpg I divide that number by 14 right? Or is it 15? If its15 then that means my tanks arecoming up 30 miles short of 18 city mpg. If its 14 then I am almost right at 18mpg in city. I still think this is pretty bad. I expectedtobe able to get 300 miles atank in only city driving.

The only reliable way to measure mileage (well, the MOST reliable way) is to always fill up completely (top off the tank), and divide the amount of miles you've gone on that tank, by the gallons it took to fill it back up. This whole using the gas gage thing just is not accurate, and if that is the way you are figuring out your mileage, no wonder noone seems to be getting the right milleage. I actually track my mileage on every tank (hence the graph that i showed earlier) so i don't even have to use the tripometer, because i can just go off my odometer... for instance, as of my fill-up this afternoon, i have driven 6273 miles, and used 323.54 gallons... that's a mileage of 19.39mpg... not to bad i think...

Any chance you'd like to just give us your *actual* mpg? It's not like it matters what size the tank is, after all...

Thanks for the comment, but actually, I got a speeding ticket a couple of months ago and if I can go the rest of this year without another ticket the ticket gets dismissed. Therefore, I use my cruise control religiously.

JeRKy 8 Owner, you seem to be VERY RESISTANT to any and all advice given you! Several posters, including myself, have told you within this thread that you ARE CALCULATING MILEAGE INCORRECTLY, then explained how to do it right. STILL, you persist to use your fuel guage and this "14 right? Or is it 15? If its15" insanity.

So you offer no alternative opinion I can come up with... Either you are just plain stupid, you can't read, or perhaps you're a troll posing as an owner, IMHO.

Otherwise with 1/2 a brain (or NO brain, if you can simply follow directions and use a caclulator) you would know EXACTLY what your mileage was, and STOP THIS USELESS (and incorrect) WHINING about how bad mileage you're getting.

Sheesh! :mad:

Well said, spinner. Sheesh indeed. :cool:

I'd be very surprised it the differences aren't simply (or mostly) driving conditions (stop & go commute, highway at 85 or 55, etc.) and driving style (throttle position, revs, etc.).

Even when I am trying my best and I think I'm driving as conservatively as I can, my girlfriend can still get better mileage out of the same car than I can.

let your women drive:D

i just past 2000 miles and refilled my tank last night (14.2 gallons) i will report my ending milage to see IF there really is a change ...

PS:note that i am using 87 oct. which already proofed to me that there is no change in mileage range.

Spink9 I did not seeyour other post on the2nd page here sorry! I am pretty lazy and barely read the 2nd page of this. I didnt know someone wrote out exact directions for ggetting the mileage. I willtry your steps on my next fillups. But can youtell me if you arealso usually at aorund 60 miles by the time you reach the 3/4 full mark in your tanks?

Jerky, stop being so fixated about what it reads on the gauge. It has no meaning, it gives you incorrect and inconsistent results, and just leads to meaningless posts when we're trying to gather real data. Just forget it, ok? Now, go back and read where about 8 people tried to tell you how to CORRECTLY compute gas mileage. Use that technique, report your results, and forget all that stuff about the gauge. It is utterly meaningless for the purpose of this discussion.

Sorry if I'm being vague or ambiguous here...

Easy on JeRKy 8 Owner. He's from Florida & they don't know how to count down there...:p

It's real simple...

1) Fill the tank all the way & set your trip odometer to zero.

2) Drive it till you need more gas.

3) Fill the tank all the way. This time & from now on, record the miles from your trip odometer & then reset it to zero again. Also, record your gallons from the pump. (If you get a receipt, the gallons will most likely be on there. Good place to record the miles.)

4) When you get a chance, divide the miles that you recorded by the gallons that you recorded. Record that number (MPG) somewhere so you can keep a permanent record of MPG for every time you do this.

Special note: If you don't fill the tank, don't reset your trip odometer to zero, but record the gallons. When you finally fill the tank, add those gallons to the gallons of the partial fill. Record & zero the miles & divide those miles & the sum of the gallons for an accurate MPG.

See? Simple.

I believe each RENESIS is hand assembled so this is most likely why most RX8's have different "personality"??

maybe have your dealer do a compression test- my mileage never got above 15, then starting going south, then it wouldnt start, now they are replacing the engine at 3600 miles

I think this is too complicated for some people. Imagine - a 4-step process (fill, drive, fill, compute) that has to be performed in the right order. You may be asking way too much. And then they're told not to count on the gas guage! Car ownership never used to be this difficult.

Hey, we're not picking on anyone in particular here so don't take offense. but for all of you in lalaland concerned about gas mileage just please make sure you're computing it accurately and correctly before posting your mileage figgers on the forum.

I willtry your steps on my next fillups. But can youtell me if you arealso usually at aorund 60 miles by the time you reach the 3/4 full mark in your tanks?

Apology accepted. I know the board can be rough sometimes, but remember the purpose here is to get facts from multiple owners, resolve issues, help one another, and enjoy each other's posts.

IOW we're TRYING to help each other, so when some seem to ignore the help, well, you can undertsand the irritation.

And yes ROUGHLY that is ABOUT what miles I have at the 3/4 mark... so back of the envelope calculation 4 x 60 miles = 240 miles. In fact, 7 of my 8 fills have been at 234, 253, 251, 245, 243, 235. But the ONLY THING that tells me is my GAS LOW LIGHT comes on somewhere about 235-250 miles, it tells me nothing of my MPG!

If anyone isnt satisfied with there RX8 I will straight up trade you for my C5 corvette. Long as it has leather and Navigation.

I sympathize with many who are experiencing poor gas mileage. My experience is good gas mileage. Last two 3/4 tanks equated to 11.8 Gallons and 245 miles of mixed driving. This isn't premier mileage but I thing it's exceptable and within the claims made by Mazda.

I don't know what percentage of owners are experiencing the poor mileage but if it is say 25% or lower they probably have something wrong with their car and should be complaining loudly to their dealer.

Again I'm sorry some are having this problem.

mine started at 13mpg then when I hit 2k it jumped to 17 , 18 area

ok my test failed.. i was using 87 but on my way home today i heard knocking at about 6K so i will purch out the tank and fill it up with 93 (again) or 91. i will do the miles count in 2 tanks from now to ensure that all 87 left over is burned out
