If they are actually serious i will be thrilled. but it seems a little strange that they had to do additional research and didnt know about the seals in the car the entire company revolves around. and it also says nothing about all of the previous quotes from mazda stating that the reason not to use synthetic was not the seals but the cat and the way synthetic burns etc... still this could be great news for those of us who believe in synthetic.

Bwaaaahahahahaha! :D

Is this the point where all of us who have posted often that synthetics are OK for the RX-8 get to say "I told you so" to everyone who swore we'd destroy our engines? :p :D :p

Regards,
Gordon

I was the one who posted (started) the thread on the "official" word on synthetic oils from Mazda and posted their e-mail to me.

I too have received the updated E-mail stating it is now OK.

I will certainly print this out and save it electronically, but Mobil 1, here I come!

Take care,
Glen

I first ran synthetic oil in my RX-7 about 6 years ago. I never had any problems with it. I just tried to stay out of the big debate on it.

When we change our oil, we seem to only change 1/2 of it because of all the coolers. I assume this synthetic and regular mix will be ok. Thanks

When I have changed the oil in my RX-7's, I have always removed the drain plug from the oil coolers as well. Obviously there is a little oil left in the lines but not very much. Quite a bit sits in the coolers so it is best to empty the system as good as possible.

Do the coolers on RX-8 have drain plugs?

A more complete change sounds better but I wonder does having them empty delay oil getting to the engine after the change? How long would it take them to fill?

Talking The end to the synthetic debate!!!!!!

Hey Guys,
I have just recieved word from Mazda about syntheti oil. Get ready. OK, here it cames. YOU CAN USE IT. They said that they did some testing and that the new seals used in the RENISIS enable you to use synthetic. Check it out. Hopefully this will end the 200 page debate in another thread about syntietic oil.

All that build up, all those exclamation points, only to be beaten to the punch by 4 days!

OK, so we had already been told - this is still very good news, and worth repeating! Still - I bet in 2 years, people will still be popping up to tell us that we can't use synthetic oils in our rotaries because when they had an FD Mazda told them not to! :D

Regards,
Gordon

Why, did you ever have it in writing from a Mazda dealer that it's NOT ok to use syn. oil? The only thing Mazda put in writing to every RX-8 owner was the specs in the owners manual - 5W20, API SL. Use a 5W20 synthetic that meets API SL, and you're complying with every specification in writing that Mazda has produced.

Regards,
Gordon

I asked for a spare quart of oil when I took delivery on my 8 from the dealer.

They put a quart of synthetic in the trun k for me. That says something, no?

Because last I heard if you put syn. oil in a reman, it voids the warrenty. Unless things have changed in the past couple months concering remans. CJ

That wasn't a remanufactured Renesis though was it? I know they used to say that about the previous generation remans...then again, the previous generation's owner's manual mentioned it specifically as well, which is not the case with the Renesis (Note: I'm one of those folks who have been ignoring that prohibition in his FD for years, so interpret that as you will :-)

From what I understand, the new 3rd gen remans are using the Renesis apex seals. But last I heard, they still don't want you running syn. with the reman motors. But things could have changed by now....I have'nt been keeping up with the remans. But still, just to be on the safe side....get it in wrighting. I'd hate to have Mazda void a warrenty claim on my FE because I used syn. oil in it. And Mazda could claim, they had no idea where that e-mail even came from....I dunno. I'm going to play it safe. CJ

Wait a minute..... anyone find it odd that the survey link in the two mentions of synth emails here is EXACTLY the same?

There is this one here, and the one uploaded by 2_Rotors.
https://www.rx8club.com/showthread.p...threadid=16688

What gives with that?

Yup, play it safe then by using exactly what Mazda specifies in the owners manual. SAE 5W20, API SL. That's it. Come on, this is easy - if your synthetic oil is 5W20 and API SL, then it meets warranty requirements.
