What matters is how much in the number of miles you've driven. For that, I'd have to defer to Mazda's recommendation, though you can send a sample of your oil to an independent test lab for their opinion. Check the Mazda6 boards for one referral. I think someone recently sent a sample of oil from his 6 (running on synthetic) in for testing, and he's now going longer between changes based upon the results he received.

I have a couple of questions which, given the history in here, I think you guys can probably answer. My most minor concern is the flooding issue, or quirk, since it might not even attain issue status. Since I have a stick shift, is there any reason not to use the push and pop technique to get the engine started? I know this is usually applied in lieu of jumping a dead battery, but would it work for a flooded engine? And does it make a difference that the engine is a rotary? I'm already taking the precautions suggested earlier in this thread, so I don't anticipate ever running into this problem, but it never hurts to know....
Secondly, since this is my first new car, I'm a little unfamiliar with the break-in period. I understand that gas mileage won't be up to par until 1k miles or so, due mainly to manufacturing imperfections that are smoothed out through running the engine over time, right? I've also heard that it's not a good idea to drive it hard during the first 500 miles or so (which is SOOO hard to avoid). If this is true, why do dealers encourage you to push the car to its limits during test drives? Maybe it's an old fashioned concept, but if anyone here has any info regarding break in, or personal experience of how they handled their first few hundred miles, I'd appreciate it if you'd share with everyone. Thanks a bunch, fellas.
So when they brought out the RX-8 and it had 4 seats... I couldn't wait. Well while my wife and I really love the way the car rides and handles, we are considering taking Mazda up on their buy back offer if we can get it. This car is rapidly becoming a regular at the dealer's repair shop.
Under 500 miles the car would VIOLENTLY pull to one side or the other and it did not matter which way the crown was on the road. The wheel would turn in your hands if you let it. Dealer cut my rotors and pronounced it as fixed. It has continued to misbehave - though no where as often.
2,000 miles the check engine light and water both appeared the same day. New plugs and evaporator and this incident is history, though it took 3 days to get the car back.
Now at 4,043 miles the engine would not start smells completely flooded. Drove the car around the block to warm it up so I could move it the ten feet necessary to get it into the garage. Reved engine to 3,000 rpm and then shut it off with engine temp 1/2 to normal operating range. 7 minute ride was more than what I thought was necessary, given that my RX-7 with 98,000 miles still only used 1/2 quart per oil change and never needed molly coddling.
1) How can I tell if the "L" flash was done?
2) Anyone else had "flooding"
3) Anyone else had the antilock brake problem?
4) Anyone take advantage and actually have Mazda buy back their RX-8? I really would hate to see it go, but my wife is now terrified of getting stuck in Jersey City at 8PM, and so am I. If the car can not be reliable it can not stay in my garage.
But man sure is a sweet lookin thing. I got it all - every option they had - every body dressing, larger wheels - super sticky tires - (But not in the snow!) My RX-7 was excellent in the snow, boy that car would GO!
flooding....some have had problems but the vast majority of us have not. "popping the clutch" is one way to get it running again if flooded. The other is to hold down the accelerator to the floor and crank until the gas has been cleared out of the chambers. From what I've heard, changing the "lead" plugs to the "hot plugs" also takes care of the issue. Personally, I've never had an issue regardless of weather/temps, whether I start/shutdown mine for a few seconds when cold or a few hours.
With the "L" reflash, my MPG went up about 20% with no discernable difference in performance. As a matter of fact, performance "feels" better, but I haven't done any testing to verify....just my "buttometer". I did do a test of performance when I first got mine this past summer and it was pretty much what the "trade rags" said it would do.
If the car is pulling violently, it could be several things....
--tire out of round
--tire balance is off
--tire has broken belt
Those would be the first things I'd check.
I'm not familiar with any anti-lock brake problems.
CEL has several fixes. Your dealer did one of them. The other is to have the EVAP unit replaced and/or to "reflash" the ECU (make sure to get the "L" reflash").
Snow driving with performance tires on any car is not a good thing. Those that have put snow tire on have reported that the car does just fine. Winter driving is more about your tires and winter driving experience than anything else.
The Mazda "buyback" offer is long gone. It was made to the first 3,000 or so folks who pre-ordered their cars with incorrect HP ratings (I was one of them). I kept my car because it is a wonderful car, regardless on what the numbers on a piece of paper said.

I had the orginal 1978? (unsure of year) and never experienced any problems, not even the clutch.
Where are the plugs on the renesis? Still on top?
I thought that a little starting ether would clean them and then reinstall. Big job? Maybe some ether in the air intake?
Dealer hasn't told he started it yet, it's snowing 6 inches here and they won't test drive it to check the vibration at 65MPH or the pulling.
I think the pulling is an ABS issue as under hard breaking the ABS should kick in. Mine has never rattled my pedal. Though I have never really tested it. I am concerned as before they cut the rotors, the wheel would have been pulled out of my wife's hands if she continued braking. It was just as likily to pull against the slope as go with it. It even switched directions of the pull when I pumped the brake. It is definitely better since they cut the rotors, though I have seen it twice since.
Bottom line, it states "put in the "L" flash to help avoid the flooding problem".
A must read for all owners, and it says so!
If you don't know where to find it, search for Mazda RX-8 TSBs. They may even be on this board, I'm sure a moderator will comment.
I'd still check the tires first to make sure everything is in order there.
I've braked mine pretty hard....I don't know if ABS kicked in or not. If it did, it was a fairly benign feeling coming from the pedal.
You could also ask your dealer to "re-seat" the brake pads....cutting the rotors is another way...
Or, it could be a combination of a tire/brake "thing".
Any car I've ever had (lots of them over 25 years of driving) that "pulled" when braking usually had pads or rotors that needed some sort of attention.
If it is related to some sort of ABS application, then the sensors are applying uneven pressure to the brakes when it kicks in. Since you didn't feel any pulsation through the brake pedal, I'd look at that last, however.
While I haven't experienced this with my RX8, in other new cars I've owned, I've had the "pulling" you described. But, I always could trace it back to me doing "hard braking" when the car was relatively new. That caused the pads to be replaced or reseated since I didn't give the brakes enough "break-in" time (no pun intended).
Anyways, here is a link to some good info on DIY unflooding for the old RX-7 (and should work fine for RX-8)
http://www.rx7.com/tech/index.html
and no, gguy, I have no mice in my car!!...LOL!!...
any thoughts from the experts is welcome.
PS I also posted this under the Buying Experience town hall...in case you are seeing double
Is so, sometimes the calipers don't release fully from the disks...that could casue a squeak from the brake area.
Also, while I doubt it, the squeak could also be coming from the sepentine belt slipping. Dealer would have to readjust the belt tensioner. Or, your serpentine belt could be "glazed" which could cause slipping (and in turn, squeaking).
While rare, if your airbox has a dirty air filter, strange noises have been known to turn up when air is being "sucked" through it.
All three cars were different. The 350Z had good pickup but i found the interior a turnoff and around town I had some trouble getting used to the cluth--we also have Boxster 5-spd. The styling seemed good but i thought this more sports car than an all-weather sporty coupe.
We then drove a 325 5spd; nice car, smooth engine and gear box, good brakes but for the money seemed like a run of the mill car--wife didn't get too excited about it.
fianlly drove the RX8--liked everything about it; the stling maybe a bit less than the performance, but it was the best of the three.
Questions:
After reviewing this board, I'd like to get a few issues resolved before we make a deision on this car:
Mileage--what is realistic highway mileage?
Oil consumption--how much oil do you use and what is the drain period? does the car use synthetic?
Gasoline--Premium or regular unleaded? I've heard different stories.
Snow tires--this car has to be 4 season--is there a tire wheel combo that will work in the winter? I'm hoping a 17" wheel will work sincethere are no 18" winter tires.
problems:
flooding--what's the fix and how wide spread is it?
Oil sensor replacement--has this been fixed now at the fatory?
Any other problems with this car?
Thanks for any help.

MPG--If you're like most, you're MPG will start out pretty dismal. As it breaks in, it should get better. Make sure that your dealer has a car with the "L" ECU reflash. If not, make that a condition of the purchase. The reflash will net you more MPG and better performance.
Expected MPG range for city driving is about 15-18 MPG. All highway will net you 19-25 MPG. Of course, all this depends on how often you take the RPMs up into the "nether" regions.
You can run the RX8 on regular, as others say there is no difference. Manual says that best performance needs Premium, but you can "run it" on regular. Personally, I wouldn't put anything but Premium in mine. The extra $2-$3 per fill-up doesn't mean anything to me by using Premium.
By all reports, those that use the car in winter have used 17" snow tires and combined with trac control, say the car does just fine. I don't drive mine in snow, however.
I use about a 1/2 qt of oil between oil changes (every 5K miles). It's always a good idea to check the oil every 2nd or 3rd fill-up regardless of the car you drive. Rotaries, by design, will use a little bit of oil.
While those who have had a "flooding issue" will say it's a pain, the vast majority of owners haven't had an issue. The sure fire way to not flood it is to make sure the engine is warmed up before shut down (mainly a winter issue). Those that have had the problem, had their dealer put in "hot plugs" (Mazda should cover this) and haven't reported any problems since.
Oil level sensor fix should already be installed on any recent RX8.
Great car....you're gonna love it if you get one.
Regarding the L ECU reflash--is there a TSB on this? I ask since a lot of dealers roll their eyes when you mention internet forum info--even though it may be right on the money.
Do you use synthetic oil?
Any idea which 17" rims would fit this car?
Anyone else had transmission issues?
Also, asked the dealer to check my 6-CD changer / player. Seems to randomly skip, stop, or can't find the track. Any thoughts on that?
I ask since suggestions like this to service guys that haven't heard of them is like water off a ducks back.
Do you use synthetic oil?
any idea which 17" rims would work on this car?
Mind you, I didn't intend to have the 8 out in those conditions! But the Blizzaks have proved themselves time and again this winter...yesterday being their biggest challenge and they came through with flying colors. I just can't say enough about them.
And if you go with the stock size, you don't have to mess with swapping out the tire pressure monitoring sensors on new wheels. Dunlop also made a snow tire in the 18" size for a good bit less but for winter assurance and no loss in dry performance the LM-22s can't be beat IMO.
Lastly, general opinion is to stick with non-synthetic oil.
Go for the 8. You won't see yourself coming and going, and it's really the best performance value out there.
mkoll - as the only other vocal AT owner here, I have to say the first 8K miles on my girl have been fine. No transmission slippage. However, it will make a nice "clunk" sound after I stop and put her into park. But she's been doing that since day one. I just want to know how you could put 3500 miles on since October?....that's when I bought mine!! I got a big lead on you!! :-)
OEM tires--is there more than one brand used on this car or is the Bridgestone RE040 the only tire mazda has chosen with this tire? Would appreciate views of the OEM tire.
Mike
oil...while I've never seen or heard that the RENESIS won't do fine with synth oil (since the manual really doesn't say anything one way or the other), the generally accepted rule of thumb is dino oil only.
tires...I've got the Potenzas on my car. I've heard that Mazda does use other brands, though. I've never checked to see if the ones on my dealer's lot has anything different. I'll do that next oil change. Like others, I think you would want 18" snows on your car in the winter for all the reasons stated here. But, they are costly. It's been reported that 17" tires/rims work just fine except you need to make sure the tire pressure sensors are recaliabrated.
Cheeze -
I only drive mine about 700 miles per month,as you can tell. We have 3 cars and I usually have 2 of them at my disposal so I don't drive my 8 when the weather is bad, especially not in the snow.
Since the weather is getting better, my total miles per month will increase some.
I heard that same clunk when I would put the car in park. I figured it was just the nature of the beast. Also, mine always seemed to hesitate a bit when shifting from reverse into drive.
I guess all I can do for now is look at my 1:18 scale diecast on my desk and hope for the best.
The more I think about this transmission thing, the more I get p'd off about it.
Will keep you posted.
and I am sorry that you live in a snowy climate!...I am spoiled here in FL....so I will quit the mileage race with ya!....
But I am glad you got the 1:18th model!!..mine is right here on my table!!....a cute redhead pulled a window out, but it's all better now!....sweet toy isn't it?....(the car not the redhead!..LOL!)
Both cars are sweet toys.
Unfortunately, at the moment they are BOTH undriveable.
Feels like temporary RX-8 withdrawl.
One more thing, I'm noticing with my 8, upon cold starts It is really hard to shift into 1st and 2nd gear for the first couple of shifts. After that it is really smoothe. Warm up times are as usaual, 5 mins every time.
Hey GGuy keep up the Good work.
There was actually a discussion about this... let's see.... found it... here it is
'11 GMC Sierra 1500; '98 Alfa 156 2.0TS; '08 Maser QP; '67 Coronet R/T; '13 Fiat 500c; '20 S90 T6; '22 MB Sprinter 2500 4x4 diesel; '97 Suzuki R Wagon; '96 Opel Astra; '11 Mini Cooper S
The only time I ever see a reduced resale value is when a car has a "rebuilt" or "salvage" title attached to it.
I'm finally getting to drive my RX8 more and more since the weather broke. There was a point in time this winter where it stayed in the garage, untouched for 3 straight weeks. The more miles I pile up, the better it drives.
That 1-2 shift was "notchy" when the car is cold. Once it warms up, things are back to normal.
I did my first (small) roadtrip in my RX8 last weekend....250 miles round trip....all highway. I got 25 MPG with the cruise set between 75-80 MPH.
vtlc - The fact that you had go through the trouble to have a rebuilt engine installed in your car is something I had never heard of before. I doubt that I could have taken it as well as you did. Mazda would have had to supply me with a brand new car for something that major. As for resale value, it probably won't make a difference if the engine they installed was new. Rebuilt sounds like it was a used one that they tinkered with in order for it to be used.
The first time around I got a 6.2-6.3 sec 0-60 run with a ~4K RPM launch on a green engine. With the RENESIS now broken in and the reflash, I should be able to shave a tenth or two off that time with the same launch.
With the warmer weather, I'm getting about 19 MPG in mixed driving. All city, stop & go driving (with plenty of 9K rpm runs thrown in), I'm getting between 16-17 MPG.
This is a August 03 build--should I expect that the sensor thing is s non issue? I'm waiting to hear from the service guy about the ECU reflash.
We've had a Boxster for 5 years and do autocrosses with it in club events and a few DE's at local tracks--mid ohio, nelson's ledges. After wheeling the RX around some S curves and on ramps my wife and I both agreed that we'll be taking this car along to the club events--it felt that good out of the box.
This problem is also being found with the Mazda 3, I should know because I'm one of the 3's owner that has the problem!!
Hope they come up with a fix soon.....
