Synthetic blend oil

Didn't mean add these myself. Sorry for confusion.
Was looking at key elements to stay away from. Eg. Zinc or other crap that could cause issues with Cats (unknown, but i am catless anyway).
The grey spec label i posted prior does have zinc added. Should i just steer clear maybe? Why bother to advertise this additive? No idea 🤔

High zinc can be bad for catalytic converters. The cars that need a lot of zinc are things like 70's Ford 302 V8 with with lifters running on the cam. We have a 72 Mustang, so we use a an oil with higher levels of zinc. I am unsure if zinc is good or bad for a rotary, there might be some info over at Bob the Oil Guy's site, but I see lots of warning to avoid high zinc in anything with a cat.
It is getting amazingly difficult to figure out what oil to use, so on our newer cars as requirements are changing constantly, I have just given in and buy the OEM stuff the manual recommends. The part that bothers me is how thin the oils are that the manuals call for and I live in hot and dank FL, so I fret over needing a little more viscosity than the OEM's provide. I then see warning that anything thicker can't get into the new tighter tolerances on modern engines. Much of this seems like a crap shoot.

The synthetic oil confusion will probably be put to bed when the MX30 (or whatever the EV with the rotary range extender is called). It's a pretty surefire bet the manual doesn't say a word about conventional oil, and there are no crazy differences that would make that recommendation any different for the Renesis other than the passage of time and changes in what oils are generally available.

I've been running this oil in all of my rx8's since 2013 from 34k miles up to 55k miles on my track car. Yes zinc is known to murder a catalytic convertor. So even though I'm running it in both of my street cars that run cats.. I'm treating the catalytic convertors as consumables since I know the engine is protected. There is a post awhile back about the lawsuits regarding the labeling of synthetic oils.. which is totally true. The marketing is crazy and there are many levels of branding for what is being called synthetic oil.
Torco SR-5R Oil
It's important to note what group base the oil is being derived from. And as others have said.. oil is oil. So regardless of synthetic or "mineral" the weight is the important part imho. 5w30 is my go to on this car. So if you want a case study.. I've got 3 Rx8's all running the same oil.. one 2009 and two 2010's. 1 with no catalytic convertor and 2 with. And none of them are being pre-mixed. Which I do concede I could probably start doing on my track car. But only slightly since I still use the factory OMP. And after having learned how to heal toe I do drive my track car harder than I did in the past.
But I'm with Spectra6000, if emissions are ignored for this car in regards to the range extender.. or however they classify it.. it'll be interesting to see which oil is in the factory manual for the engine. It will still burn oil since it is a rotary. Perhaps it'll have a dedicated apex oil lubrication system. Like what others do with the sohn adapter? Similar to what we see with diesel cars and their defi fuel additives.
TLDR: This is an old horse that will keep getting beat till all the horses are dead IMHO. Just run oil that is suitable for your environment. CHART

I'm genuinely looking forward to seeing the details on the range extender. It's fascinating that Mazda decided to use a rotary range extender, because there's certainly a logic to it, but there's a lot more logic against it. More critically, the logic FOR it makes a lot more sense if there are other applications. The displacement of the range extender will be very telling. It'll for sure push the envelope a little, but only a little because we're talking a fraction of the R&D budget of one of the smaller OEMs. There will be gains, but they'll be small enough that things might be able to translate pretty easily. Based on patent drawings I've seen so far, direct injection is the big one. There was a photo of a prototype that showed a single spark plug as well that could be an interesting detail. Ignition systems are now able to do multiple finely timed and controlled spark events, so it may be all that's needed... Lots to unpack once the package arrives. Oil is honestly not even on the radar, because I'm pretty confident it's a foregone conclusion.

All Mazda dealer oil is synthetic, so the spec will be SN or SM synthetic recommended by default. I don't know that you can take that verbatim to the Renny which, unlike the range extender, has to work in a wide load and speed range, but it doesn't super matter. Oil has evolved massively since the RX8 was introduced. A good non-PAO synth with modern rating is good both for the engine and for the cat.

nothing exposes the full-tard in people more than an oil topic, just consider the usual topic starter and participants so while I have no opinion to offer here because none of said persons will hear the wisdom of the message regardless, this interestingly enough popped up the other day and should help boost and regenerate that which you thrive on

Sick of these ***** on this forum. Looks like many of these oil threads need updating. Oil can always be an ongoing topic because the car is almost 20 years old and oil has changed much since then. Since almost nobody puts in what's actually on the oil cap, I'd say the oil debate is ongoing and ever prevalent

it was the same when the RX8 was new, just pick any new car and their forum has all the same thing.
because the very nature of full-tard is to go all the way with it
it’s even a contest now to see who can take it to the next level; thinking they’re taking it up a notch, when in fact they’re spiraling the entire shebang downward
as it is and has been in every society leading up to when it collapses inward upon itself, just as the Tower of Babel did fall, and will do once more again.
and as was said long ago;
What is that thing taking place? the same thing as shall be taking place. And what is that thing being done? The same thing that shall be done. And there is not any thing being newly made under the sun. Who shall speak and shall say? Behold this is new!
Already it has happened in the ages to the ones having taken place before us. There is no remembrance to the first things and indeed to the last things being, there will not be a remembrance of them, with the ones being born at the latter end.
————
no, they don’t even recognize that now is the latter end let alone anything else. That being, there’s nothing new going on today that didn’t already happen before along with the same end result we’re drawing ever nearer to. Because people don’t have the eye to see or the ear to hear anything beyond the deception of the physical world; they know the world and they hear the world, and the world hear’s them.
Even the words above, of there being nothing new under the sun above; attributed to King Solomon, and most don’t recognize him as a man who possessed everything the world could offer in every way, and not only falling into the deepest depths of his own meaningless vanity, but it directly being the cause for it. It being exactly what he asked for and the strong delusion of it being so granted. In the final accounting, a simple and foolish man with nothing fared better than him, though the eyes and ears of the world are blind and deaf to such a simple and obvious truth. The only man associated with the number six hundred sixty six; twice even, and referred to as the “anti-David” in the Hebrew text. Neither recognizing that the synagogue he built was nothing more than a house full of graven images.
Deceived by the Highest Power having dwelled there, forgetting the very words of his own father saying; “if I ascend into heaven thou are there, and if I make my bed in hell thou are there”. After all, who was his mother and how did he himself become into being? Many simple and obvious truths that the words being seen with fleshly eyes and the sound of the words being read ringing within fleshly ears, yet the fleshly mind neither knows nor perceives the spirit, the truth of them.
As the King of Kings and Lord of Lords did say; you do err; neither fully comprehending the words nor the power of the Highest. The same power that has the entire world under the strong delusion, yet they comprehend it not. Neither believing it to be so, or even possible, or attributing it to the future and their self somehow being exempt. Yet they do err in such a belief, just as they were all foretold.

You scold people about going full 'tard, and then you post something like this.
Limited self-awareness, apparently...
Stick to mechanics.

DO NOT run any synthetic blend of oil in your Renesis engine if you are still using the Oil metering pump to inject oil. Synthetic oil wont completely burn up inside your engine, and that can leave deposits that can lead to seal failure over time. If you are using a separate SOHN adaptor which closes off those oil metering lines, and injects new two-stroke oil, then you can use synthetic blend oil. Mazda will tell you they dont know the long-term results of running synthetic oil in RX8.
Be safe, dont risk harming your engine.

This notion is about a decade out of date. Oil has changed a lot and not all synthetics ever had deposit forming characteristics like that. Most modern cars burn some oil, and oils have evolved to burned.
Of course there is nothing wrong with continuing to run regular oil, just realize that lower groups of oil are generally *worse* at deposit forming than group IV and V "synthetics"
