I haven't seen Ray's "shed" over at BHR, but I bet it's pretty sweet.

re oil
 

I know this debate has been going on for a few years. .but here's the information available to me..
a tsb from mazda said don't use synthetic oil.
all the private rotary engine builders in Europe recommend mineral oil ...to the point they won't honour warranties without proof of mineral oil use...mine included... a year ago...not ten years. .
...any engines torn apart I've seen burning synthetic are gunky brown inside...
mazda have stopped development and research on the rotary as we all know. ..so the last tsb says...don't use synthetic. ..
so all of you lot do what you want. ..put used Mcdonalds fry oil for all i care..
if someone else on this site days you better check the tractor beam and the flux capacitor you better jump to that too..
do i want help? ...
no because the problem is solved. ..
I've no burning smell ..
and your information is wildly inaccurate. .
just to be clear..mazda is based in japan...thats where the tsb came from. ..
thats who built the engine. ..
you yanks really think there's nothing outside of America do you?
its a Japanese car. ..the tsb came from japan...

Oh well if it's from Japan, then I guess there's nothing more to say. Those guys definitely know how to make a rotary reliable.

Cool! You've got it all figured out then. :hahano:

Absolutely! Now if you will excuse me, I will follow Mazda's recommendation of 8000km~10000km oil change intervals with conventional oil in a rotary engine.

Out of all seriousness, another reason Mazda mostly said no synthetic because like BHR mentioned, synthetic oil are all different. Pennzoil Ultra with PurePlus is actually made from natural gas as base stock, while conventional oil is mostly the same.

Did mazda make a reliable rotary engine lol:o::mdrmed:
well i don't think enthusiasts buy these cars for 300.000 mile trouble free motoring...a Toyota corolla it is not.
a beautifully designed perfectly balanced street racer it most definitely is.
a bit of digging and you will find mazdas own oil is a highly refined mineral oil...it may say synthetic. .but its syntheticly engineered. ..
look im not a sucker for main dealer nonsense trying to suck you in buying their parts for no reason. .
but im going with their tsb on this one...the private rotary builders have seen hundreds of rebuilds and are recommending mineral.
mazda says mineral.
private experts say mineral.
mazdas super duper expensive own brand is in fact mineral.
so that's what i am putting in my engine..
​​​​​​​you have spent a few years tinkering with your cars so you obviously know better than someone who has built hundreds of engines.

You can put whatever you want, no objections from anyone. But just realize that the "synthetic" label, and by extension that TSB, are meaningless in 2018. As you say some synthetics are refined crude, others are actually synthesized and their chemistry is completely different, including deposit forming and burning byproducts. The API (the oil standards institute) does not use the word "synthetic" anywhere in their documentation because it means nothing.

Considering you have 81 posts in 10 years, and contribute practically nothing to the forum, I would rate your opinion's worth at slightly lower than used toilet paper.

Have a nice day.:)

On the contrary I see a few rebuilders recommend synthetic, BHR being one, obviously.

Oils do fall under different classes depending on how they are made. All mineral/conventional fall under a single class so they are all fundamentally the same, with the difference being just the additive package. Test one and you know how all conventional will behave.

Synthetics usually fall under different classes. Mazda likely tested a couple, found that some of them form deposits, and said "no synthetic." It's easier for them because otherwise they will have to test every single one and give people a list of which oil from which brand works and that's too much work.

@bigcajun...ive been building engines for the past ten years. ..not on.this site constantly .. if you got your finger out of your ass and off your keyboard. .maybe get some oil on it doing a bit of actual work. .you might learn something. .

Whoa! We got real keyboard hero here fellas! :lol:

Rebuilding engines for ten years and needs help to find a burning smell.
Mad skillz bro.

Btw, I was a professional mechanic for 10 years and got out of it to get into a better career as a CNC machinist.
I also bought my 8 six years ago with 18k miles on it, used Mobil1 synthetic exclusively since then, now at over 85k on the original engine, so your opinion is crap.

When I do occasionally ask for assistance here, I don't then insult the members who respond.
But if I see some clown parachute in here and start insulting respected members who are always trying to help others with even simple problems like burning smells, I resent it.
Especially when they make asinine statements like oil in intakes is normal.

Act like a jerk, get treated like one.

esp
respected members lol ...what do you think this is...academy awards for keyboard warriors.
respect my balls...
and regardless of whatever nonsense you are spouting I've been on this site since 2008...
i can also play the stalking game. .you have been on it a few years..and you seem to be on it non stop..i don't know how much "machining" or rx8 repairs you get done with all your keboard warrioring...your the first one to comment on everything. .your never off this site...
people like you ruin these clubs for everyone. ..
a little cliche of know it alls ...are you even interested in cars at all or do you just enjoy hoisting someone not in your circle of friends into the spotlight and trying ridicule them ..where you try to make yourself feel superior. ..
its always the same. ..king dick you think you are...its not even about cars ...its just about you making yourself feel superior
if i follow your threads how many times have you done this?...
I doubt if you have ever even had an engine out of a car at all.
you just like bangin away at your keyboard. ..
this site can be a valuable source of information but people like you ruin it by turning it into a platform for personal vendettas and pushing your ego...
Facebook is the place for you. .not car forums. ..

Somebody needs a Snickers.

^yep

If you don't have anything to add, just agree to disagree. You are making yourself look like the keyboard warrior you loath.

Again, Mazda's official advice is just "effects of synthetics are unknown, so synthetics are not recommended", not "use a drop of synthetic and your Renesis will shoot out of the car at supersonic speed." And again, I don't think anyone here follow the 8000~10000km OCI the Owner's Manual recommends, or shift at low RPM like the Owner's Manual recommends.

​​​​​​​....

I agree to disagree...

​​​​​​​

OK, you obviously know all about me.
I'm a huge troll who comes on here just to inflate my ego and belittle people.
Nailed it.

Now, if you were ever on here to do anything other than have someone else solve your problems for you, you'd know everything you just posted about me is not even close to how I participate in this forum.

But since you're never on here, you really don't know, but that doesn't stop you from spouting nonsense and making a fool of yourself.
​​​​​​​
Since you seem to be the type that has to have the last word, it's all yours.
I'll just leave this here for you little buddy.
