But the Renisis is a new design correct?
I agree with your statement above though that Mazda did drop the ball on educating buyers about the rotary, and that with the care you stated they will likely have no problems. I would have de-carbed every 5k if Mazda had told me to. But on the other side of the coin most consumers would walk away once you listed all of that that needs to be done and likely it would be the death nail of the rotary.

Through the years I've probably talked just as many out of owning a rotary as I have into owning...I honestly don't believe these engines take much, but they do take a little more than their piston counterpart to keep going and I agree that many aren't willing to do the extras...

Seeing that you you are two peas in a pod, lets address you together.
I understand your point and agree with the statistical guide lines which need to be followed to assure accuracy. But as I said this can't happen with what we have so we will simply have to adjust for a margin of error. You also are making the assumption that the sampling will not be representative of all RX-8 owners. For all you know it could be. The operative word here is you just don't know. So we are left with a survey which may or may not be accurate. True?
Again if you have a better way to gather this data which is realistic I'm all ears. One more thing that makes me wounder is that as you are laying out all this and why it will be inaccurate you presently have a very similar poll exploring engine failure. Of course you were expecting your poll to show there is nothing wrong but when it did the exact opposite you started only then to denounce it statically....... interesting. Kinda makes you look like you're cherry picking what is and is not accurate.
....and yet you stayed clear of the RX-8 04 because of extensive research? Maybe because you had direct access to Mazda's records? No you did it because of a few posts you read here and formulated a buying decision based on it. Yet when we try to collect some hard numbers relating to known issues that can effect engine failure you jump on the statistical band wagon. I know the numbers will not be perfect but they will be better then anything we have or anything you have used to make buying decision in the past.
Now you seem to be a little paranoid in your support of the RX my friend, you feel a view you don't support must be bad for the RX and that the people have a grand agenda as to the this insidious survey. Well I hate to pop your bubble but I'm just out for information to help me maintain my car and hopefully put my mind at ease as to the future of my car.
So unless you can provide a more accurate why of doing this........
You know guys, there are two type of people in the world, those who get things done and those who tell you you can't. Which are you?

What most people don't realize is that a small sample size can be statistically meaningful. Having only a few hundred people voting is NOT the problem with these informal "polls".
No, the problem is that these "polls" are not drawn from what's called a representative sample of the whole RX-8 population, i.e. all the people in the world who have RX-8s. All this "poll" can tell you is how people voted on this poll, but the info cannot be used to draw conclusions about the RX-8 population at large.
So again, the problem is not small sample size; it's a sample not representative of all 8 owners.

^ Exactly.
No one here is sticking their head in the sand. From the buying inquiries, most answers are to get 05+ models. Not it has to be manual, premix with Idemitsu at 4oz, 5w30 synth, build no. after X years, must not live in Vegas or Florida... forget about Singapore as they are far too hot, un-modified, driverless, Shell V-Power 93 etc.... Shall you add this to the poll as well? Can you see how ridiculous this gets?
When I was out looking for an RX-8 I knew to stay clear of 04s. Same with the 911 964 models. Stay away from 1980 and 1990 thanks to disintegrating flywheel. Similarly when I was looking for an M3, stay away from 01/02 S54 engines as they go KABOOM. Apart from getting the mfg defect logs, this is good enough.
Hence I don't see the reason for this witch hunt other than some sort of vendetta. But hey if I happen to have bought a Scion tC because I am couldn't afford the rx-8 and feel a bit small, I can see how enjoyable this poll can be.
Anyhow this has been quite entertaining for my slowwwww friday. Time to go home. Can't wait to jump into my 8 and take on the twisties.

True but, we both know that small changes can have large consequence. The clearance are tighter in this engine, apex seals thinner, oiling inadequate???, the side ports are very new. I remember reading that Mazda tested side ports before but had fowling issues with them. So even though it is a 13B it has enough changes that questions still need to be answered and I'll be the first to say I don't have them but would like to help find them.
The port configuration is new...a few other advancements here and there...but at its heart - it is a 13B. And the Renesis is manufactured to much tighter tolerances than previous 13Bs...so quality control - in that aspect, has improved.
Through the years I've probably talked just as many out of owning a rotary as I have into owning...I honestly don't believe these engines take much, but they do take a little more than their piston counterpart to keep going and I agree that many aren't willing to do the extras...
