Here's a simple explanation... RX8 Renesis is different than RX7.

So new clearances, rotor apex seal tolerances, etc, etc, etc. have the same to do with the RX7?


NO THEY DON'T!

So I should I just drop an early 13B in my RX8 and then agree with you? If I do that , and run Synthetic, will you pay for any non-warranty issues that arise?

 

I can't imagine it would be pretty to have a seal "stick" at 9K rpm.
I think it is illegal to stick seals anyway; unless you are Inuit. :-)

 

Hmmm, nothing but dino oil for me.

My tail pipe are EXTRA black, and my power actually seems to be down for this cold time of the year.

If there was a way to block your comments, I'd enable it!

This thread ROCKS!

 

DUde, i dont give a **** if you dont want to believe. bottom line is that both engines use the same apex seals and if they go bad are simply because of stupid owners who wont listen!

unfortunaly this is a process that takes time to blow your engine.. I will laugh when you blow your engine at 50K

Im done here///time will teach you guys

 

Maybe I'm just dumb, but wouldn't the engine not turn over (i.e locked up) if the apex seals were sticking. Unless the result of the sticking seals meant a small piece of the seal broke each time the engine turned over.

 

I'm not saying either.

The brochures arrived from Mazda to the dealer. I'm not sure how Mazda wanted them distributed. My dealer percieved a problem after Rx8's arrived on flatbeds. These cars were flooded. My service department advisor also told me that they flooded one in the lot themselves (lots of moving cars for very short distances).

They (the dealer) responded to this issue with a letter of their own. With that letter came the Brochure I posted.

If Mazda wanted to send these directly to us....I dont see why they could not. My opinion is that they were sent to be placed in cars on the lot....like the "quick tips" guide that was tied around the stick shift. The new brochure addresses the issues now being observed. Oil consumption, and possibility of flooding.

 

What are the part numbers for each?

I think I have Monday off, I'm going to go down and actually order all of the manuals.

I'll ask the techs to look it up and cross reference... what year/model where you referring to?

If that's the case, I'll post it up and agree with you!!!

But for now:

Where in the RX8 Owner documentation does it say that you can NOT RUN SYNTHETICS?

 

If the apex seal is sticking or crackin or letting oil through, your engine will stilll work up until the point you rotors bent due to lack of lubrication, carbon build up.etc. Rotary engines often times can run with a blown apex seals, but most of the time, they seize to work.

There is plenty of times when only just 1 rotor loses compression, yet the car still runs with the other. It lacks of power but still runs.

Is hard to tell, but a compression test will tell you for sure.

 

They already showed you a scanned mailers from MAZDA and a copy of a letter sent directly from MAZDA Corp to a forum member, Why dont you email mazda just like he did.

But, im sorry to say ...You are just hard headed!

 

Does the engine lose compression, as well? It would make sense if the apex seal wasn't "sealing" properly.

 

ohh yes thank you RX7FD guy.....I almost forgot. The APEX seals on the RENESIS are new too. An all new design.....never used before. Your going to teach us......

 

Crap, I thought he said he was done here.

 

What do you think Mazda would say if you wrote them an email asking about the use of Protek-R in your fuel with the RX-8? Do that and post the results.

OK, I'll save you the trouble...they're going to tell you not to do it! Are you then going to reverse your previous statements about how great the stuff is for rotary engines? Are you going to stop using it?

Where did you hear that?? it uses the same 2MM MAZDA Apex seal. Same material, same thickness, same everything, the only difference is is the shape to be able to fit then renesis engine

So how is it different other than the shape?

 

I'm not hard headed. If Mazda did not want me to run SL 5W-30, then why did they not specify SYNTHETICS?


Sorry for repeating mysself, but MAZDA did NOT show me these DOCUMENTS.

And until I have have OFFICIAL proof to the average owner, I'm going to defend the OFFICIAL DOCUMENTATION presented to ALL owners.

Until that time comes, it's all hearseay.


Why can't you understand that?

And if we are on another page.... I'm solely running dino in my car, but just keeping it real for the people here.

Why is this so difficult with you?

 

OK, guys this is getting too intense for me now.

My take on this topic is that based on info from Gyro with this new manual, Mazda recommends against Synthetic oils. I look forward to getting this from Mazda.

Thanks for all the info, this was actually worthwhile! Now I am gonna watch a movie.

Good Night

 

C'mon, what movie could possibly rival this for entertainment???

It is used in the oil not fuel...and to answer your question...
Do you think mazda will agree or approve of the use of HKS, GREDDY SIngle Turbos in RX-7s, of course they wont. When have you heard of any car maker to aprove anything being done for their cars through a third party company.

Petit Racing has been building rotary engines for years and their vehicles are alot more reliable than factory mazda's...so i would trusth them more than i would trusth mazda.

Per example mazda swears that the intercooler they used works great on RX-7s or their downpipes yet in reality, the downpipe its the worst thing an RX7, it so restriced and it produces unnesseary heat. and the Intercooler is tiny! WTF where they thinking to put such a small intercooler on a turbo Car?? So no...I dont trusth mazda

 

Page 111 of the RX8 design book by Yamaguchi.
The Renesis Apex seal is now two-piece, and it heith is reduced to 4.5mm from the previous 8mm.

 

You guys crack me up. Anyway, RX7FD3, I think the seals are different. I remember reading about it in the big book sent out to all the pre-ordered owners. The rotor design in conjunction with the seals is different, too. I'm too lazy to look it up right now, but I think it does something to lessen the stress on the seal during cumbustion.

 

Good night, and I'm so glad we agree!

Until we get this Mazda, what's point on arguing about it with RX7 owners that know nothing about the documentation given with a new RX8?

Show me the docs delivered personally to my name, and I'll praise the MNAO lords that have given us this wonderful car!

Have I mentioned that this thread rocks?

RX8 owners need to open the holy book of owners manuals and read passage 8-9 in that divine book provided to you by the dealer that you took delivery from!

In no way is Satan mentioned in that passage, much less the sin of synthetic oils. If oil spec defined is the bread, is the bread different from white, wheat, whole grain, sour dough, etc etc, until the lord (Mazda) officially invokes it's wrath upon us with written holy documentation that certain breads are not good for the spirit?

 

Good stuff. I need to find a source for that book!

 

See above! The rotary lord is beconing you to look above for facts!

[heh, I'm not even religious, but this is fun!]

 

My dealer (Moss Robertson of Gainesville) gave me one. Decent bunch up there.

 

thank you chrisbert.....I'm glad I dont have to fire up the scanner again.

Also RX7FD, the side seals are completely new. apex AND side.
