so i sorta need an answer. if I put royal purple in my 2004 rx-8 w/ 58k miles, what oil viscosity should I use. It's also starting to get cool here. best recommendation? I need to do an oil change soon. Also, I have no idea what oil was used in this motor before I bought it. thanks in advance!
I'm starting to think nycgps has stock in high viscosity oils.

I run RP 5w30 and my car made 210 rwhp this summer, normally aspirated. This is on a car that ran Castrol GTX 5w20 for most the first 40k miles. So I don't think there is an issue with loosing compression when switching from dino to synthetic.
Personally, I would never run a 10wX or 15wX in a car that experiences a cold climate in the winter. This just seems like bad advice to me, particularly if you make a lot of trips under 10-15 minutes.
But in the end, we're all just guessing. Some of the investigations that are happening are very interesting, and will probably lead to a better understanding eventually, but right now I've seen nothing that leads me to believe that "the" answer is known yet. So I stick with a reputable synthetic that is slightly heavier than what the factory reccomends in the US, and is in fact consistent with factory reccomendations elsehwere in the world.

ΟΚ, we have a serious issue here...
nycgps i highly respect your opinions and i have informed my buddies at the Greek Forum www.RX8Forum.gr many times on your manuscripts.
OK, the renesis does not have a head gasket, but it is full of seals !!
oil seals all around and everywhere.
also, one of the first rebuild threads on expo's motor, was concluded recently: the cause was switching from sth dino to Red Line i think, and that was the culpit for an oil leak at the front of the engine.
in Greece, generally speaking, most Renesis motors are very low mileage. so they can switch easily to full synth.
i am one of the few with 56K miles/95K klm. the first 1-2 years on Divinol 5/30 and another 2 on Dexelia 5/30, all OEM European recommendations.
do you think switching is an option ?? i feel kinda caved in the OEM old school selection...
MM/ RG or all other major contributors, i would like your opinion as well
many thanx !!!

if Synthetic is so bad, You still havent explain why MAZDA JAPAN SELLS FULL SYNTHETIC OIL to Rotary Engine owners
So in the end, you are nothing but just full of ****.
I think noobs like you missed out a big discussion we had about oil just maybe a week or 2 ago. We discuss friendly, with proofs and data. unlike you, you got nothing. nada, ZERO. all you got was crap.
that simply means you dont even know what you're talking about, stop dodging my question. Just answer me : "If Synthetic is sooooo evil/bad, why Mazda Japan sells it to Rotary owners? Especially RX-8 Owners?"
Come back when you have an answer (Guess I will never see you again ?)

Ok nygps,
Here's your answer.
I forwarded your poster to MNAO, and they translated as best they could. The part that you missed I hilited in red. See below.
MNAO told me that Mazda has developed a very special blend of synthetic oil for the rotary engine, and it is available in Japan. As of this moment, it is not available in the USA and many other countries, nor is it going to be available, if ever, for use here and in most other countries.
It would be too difficult to import into this country for various reasons that they do not wish to or have to explain to you.
After being kind enough to provide this information, they again cautioned me strongly against the use of any synthetic/synthetic blend available in the USA.
You will just have to accept the above response as it was relayed to me.
Consider it as they are doing you a favor in telling you not to use synth based oils.
They also advise to continue to use 5W-20 oil for use in temps between -20 and +120 degrees average daytime temps, which covers most of the USA. The new '09 and later cars OMP is designed to work best with 5W-20 as well.
You and your "expert" colleagues can continue to talk about the virtues of synth oil, but I'll listen to my contacts at MNAO.
Shinsereneshisu is, RENESIS Akira Makoto Mazda is dedicated to oil. PAO ※ based oil ester as a main component containing a combination of synthetic oil is 100%, RENESIS what the properties are suitable for adoption.
Viscosity is required for driving performance of a sports car engine is set to 0W-30.
※ PAO: Polyalpha-Olefin (polyalphaolefin) synthetic chemical acronym for
Engine wear and RE (rotary engine) to run both as a sports car that was Shinsereneshisu RENESIS is developed for the oil.
RENESIS worsen because the gas sealing performance due to the formation of carbon deposits, it was not ever recommend the use of synthetic oil.
Shinsereneshisu, while demonstrating a high abrasion resistance as a synthetic oil, so to achieve a major reduction of carbon deposits in the oil composition of the commission was canceled so far Tale, RE (rotary engine) sports car ran as while maintaining the full exercise can improve the durability of the engine.

*sigh*
people that knows absolutely nothing about oil nor this engine talking **** here LOL.
Very special blend? oh since when did Mazda make their own oil?
and if this blend is all that "Special" and will prolong the engine by 1230812408143 times. Mazda should've sold them in the states to save their "Rotary brand image" in the first place, right? make sense? no they didn't.
Cuz there is no special blend.
just like any other auto manufacture who "claim" that everybody should use their "own factory oil" cuz its "special." Like Mazda dealership here, rofl they use motorcraft 5w20 as their "factory" oil LOL. Why? cuz Ford uses them
and its cheap(very important)
do you even know what PAO means? and what group it belongs too?
oh yeah this thread has all the information. but I guess you're too dumb & ignorant to read them?
Carbon deposit has been a problem with rotary engine since ahhh in NSU labs. oh yes it happens even in the KKM prototype. I guess again you're too dumb to know that?
Another thing is not all oil are created equal. there are tear downs of engines with nothing but Royal Purple in it, holy **** its shinny clean. So yea you failed again.
oh yes one more thing, ALL, I repeat, ALL your o-holy 5w20 has SYNTHETIC OIL in it ... thats the "only way" to get to 5w20 weight ... but I guess you and your "source" again are too dumb to know that? HAHAHAHAHA
Go suck it, cuz you got nothing to back yourself up. Simple as that.

I would rather try to keep my engine running clean at all time
if the seal fails. Synthetic or not, it will still fail.
At least with Synthetic I know the seal has failed so I can get it repair before it does more damage. (a housing cost 541 bux EACH, even with my racer discount)

It's a bit like Mazda Australia "recommending their MRO" Mazda Rotary Oil 5W30 at twice the price of similar, why? because they make money and Two because Castrol Australia (BP) Bottles it for them...they have done a commercial deal.
Why do people think when you go to Castrol Australia's Website to their LUBE Locater, when you put in Oil for RX-8 is comes back as "SEE YOUR MAZDA DEALER" for, because Mazda did a deal with BP/Castrol.
http://www.datateck.com.au/lube/castr_au/default.asp
As I say, do you think Castrol would NOT sell it's own Oil if it could or if there was not an "arrangement"?
What I get pissed off about are Mazda Dealers saying "it is specially Formulated and from Mazda Japan"....BS

Yea Royal purple doesnt know **** about oil. they put a load of BS up and their oil is just Canola oil that I bought 2 days ago for cooking with purple dye. Ahh must be true ... same thing for redline, BP, mobil1, Idemitsu, Eneos, Autozone, peak, argh ... and so and so ...
thats it? come on, you can do better than that. feed me with more bs. it entertained me a lot. A LOT !

It's amazing where in Australia, if I understand your post, Castrol promotes synth, whereas here in the US they quote the following:
From the US site http://www.castrol.com/castrol/ifram...tentId=7027529
Synthetic products are not recommended in rotary engines. A number of years ago, Mazda evaluated the performance of synthetic oils and determined that their characteristics may result in lower compression pressure or excess oil consumption due to insufficient lubrication of special seals and the rotor surface. In fact, the recommendation against the use of synthetics continues to stand for their RX7and RX8 rotary engines today. We cannot recommend the use of Castrol SYNTEC and SYNTEC Blend in Mazda rotary engines because we respect the decision made by Mazda.
Go figure this **** out!

That is another load of BS, IF the 5W20 was the best for the 09 EMOP's, then you would also think Mazda Japan's Printed Owners manuals we use in Australia are wrong, because they list ALL OIL Weights at whatever your climate or Choice desires..BTW, Same EMOP's etc Here as the USA, and Europe.
Cant you tell that he has a hard time accepting facts? Jesus ... the earth must be flat ... seriously ...

great deal at wal-mart
nygps,
Hop down to your local wal-mart and pick up a 5qt. jug of their own 5W-20 house brand. At $.75/qt., it's guaranteed to meet or exceed industry standards and protect your engine or your money back!

Rx let me give you more of a different view based on what we've gathered here in the forum.
I'm not sure where you're from but your manual is applicable for where you're located yet keep in mind it does not state the same in other countries. In the USA for example, there is no reference to use or not use synthetics. It simply just recommends using 5w-20.
So if from your view we stick religiously by what Mazda says, if the engine goes bad then they replace it so long we show proof we changed it with their recommended oil. The thing is for us in the States, since it doesn't mandatory say you must use 5w-20 only, they have no grounds to deny us the engine replacement so long we show proof of continual oil change.
Secondly, the only known issue in the past from using syn was the apex seals on the rotors possibly deteriorating and losing seal. This was an issue (on 04-05 models I believe but was fixed afterward) and can easily be deterred with the Sohn OMP adapter which a lot of us use so we can give the engine syn oil which protects it a lot better as research has shown even with rotaries as well as feeding your apex seals proper oil that is meant for it such as, 2-stroke oil that was meant to be burned. 5w-20 oil or rather any oil not compatible for being burned does nothing helpful but rather can contribute to more carbon deposits.
In conclusions, for us in the States or any other country that does not have the warning of the synthetics, we can use whatever we want and get the double benefit of using it along with a Sohn OMP adapter to give it proper oil for the long run. I understand if your manual says you must not use syn then that's your call as if your engine fails and you are using it they could not uphold the 8yr warranty promise. But for us that do not have this restriction, we prefer to use oil that help will lengthen the life of this engine.

Rx let me give you more of a different view based on what we've gathered here in the forum.
I'm not sure where you're from but your manual is applicable for where you're located yet keep in mind it does not state the same in other countries. In the USA for example, there is no reference to use or not use synthetics. It simply just recommends using 5w-20.
So if from your view we stick religiously by what Mazda says, if the engine goes bad then they replace it so long we show proof we changed it with their recommended oil. The thing is for us in the States, since it doesn't mandatory say you must use 5w-20 only, they have no grounds to deny us the engine replacement so long we show proof of continual oil change.
Secondly, the only known issue in the past from using syn was the apex seals on the rotors possibly deteriorating and losing seal. This was an issue (on 04-05 models I believe but was fixed afterward) and can easily be deterred with the Sohn OMP adapter which a lot of us use so we can give the engine syn oil which protects it a lot better as research has shown even with rotaries as well as feeding your apex seals proper oil that is meant for it such as, 2-stroke oil that was meant to be burned. 5w-20 oil or rather any oil not compatible for being burned does nothing helpful but rather can contribute to more carbon deposits.
In conclusions, for us in the States or any other country that does not have the warning of the synthetics, we can use whatever we want and get the double benefit of using it along with a Sohn OMP adapter to give it proper oil for the long run. I understand if your manual says you must not use syn then that's your call as if your engine fails and you are using it they could not uphold the 8yr warranty promise. But for us that do not have this restriction, we prefer to use oil that help will lengthen the life of this engine.

There is no known issue using synthetic in this engine PERIOD. It was not an issue in "04-05 models".
You're confused.
The only KNOWN issue using synthetic in rotaries dates back DECADES, when the additives in synthetics would deteriorate certain seals. And that is the ONLY reason why this controversy continues.
Your entire post is just a long run-on sentence.
