Synthetic I think will get you through a stint where you are unable to find Dino or blended but I personally would not run it long term or for the life of the engine.

 

On a stock car, If you change your oil often, a good Dino is just fine.

 

it doesn't mean the standard/requirements? yes, but that does not mean its bad in any way.

if you have too much ZDDP for example, you still "fail" the latest API standard.

does that mean its bad? nope. its actually better.

This is another reason why I always prefer SJ rating oil than SN(newest) or SM.

 

Bad quality Synthetic (or FAKE Synthetic like Most Syntec and Valvoline, etc) are actually worst than a good Dino.

 

I'm not saying it's bad, just that they can't test every oil so Royal Purple may be okay but you just don't know if others are unless they have been tested. Every synthetic oil manufacturer say theirs is the best but at least if the meets requirements of some type of industry standard test, it will be pretty safe. I don't know, if your oil meets or exceeds industry standards then why not have them test it Money? Smart marketing?

 

Yes, and I always thought you can not purchase a 5W20 or 5W30 that is 100% Dino, in other words they have to "blend" synthetic to get to the 5W and 20 requirement...so it is not and cant be 100% Dino (the so called 5W-- grade dino oils).

Where in fact they are just semi-synthetics.(Dino and Synth).

 

Guess I stand corrected. Hey, everyone has to start somewhere and start learning. I'm willing to learn, but I dont think it was necessary to be such an @sshole about it. You could have corrected me without coming off like a condesceding *****.

Seriously, not sure why I'm trying to sift through all of the crap on this website to learn if this is what's going to happen when I post. I've seen many other car communities that are more welcoming.

This is the problem with forums these days. @ssholes running around being dicks to everyone who isnt 100% accurate about something. Nobody is perfect and knows everything.

What do you do? Sit around waiting for newcomers to make a post and then flame? Is that what gets you off?

And I wasnt talking about the there not being a major difference between dino and synthetic. I KNOW there is a big difference between to two oils. I was implying that it doesnt SEEM (based on what I've read) like it will make a major difference to your engine in the long run as long as it's maintained well.

Sorry for being so obvious. I was just trying to sum up what I read.... showing that I'm learning from this site. Hey, if I learned something that was wrong then correct me politely in the futute!

 

NYCGPS can be dick head, don't take him seriously.

 

I have apparently been using an oil (RP) in rotaries for over the past decade that does "not meet certain industry standards". I have also never had an engine failure. Then again I also asked the highest rotary person in the world his opinion of it a Sevenstock (zoom44 was also present as a witness) several years ago and he said it was fine. But hey, an official lawyer and accountant written corporate memo says not to use it so you'd better not! Ignorance is bliss.

 

Lol---1st post on this thread was 2003!!!!
Still the same stuff.
OD

 

I get it RG, you have never had a rotary fail I wish this Renesis owner could say the same.

It's hilarious, it just keeps sucking you back in, over and over again.

 

Another lesson one must learn on their own is figuring out which posters to listen to on these boards. There are the posters here that think they know something by the measure of their post counts. It doesn't take long to figure those posters out who know their **** compared to those that like to just blow ****.

 

/\ I am a **** Blower!

BTW, RX-8 Fans..lots and lots of Updated TSB's and More, in both Tech Sections for Series 1 and Series 2's...

A few are "very" interesting..

 

lol..

 

sum up what you read ... ok, hmm.

You're very welcome, Mr. Obvious.

Truth hurts.

 

Thank you sir for da kind comment. Im sure it helped this thread by a significant margin.

tell me about it.

this thread is here for so long that some of the members already MIA -_-

 

You guys want to know what gets my E-PEEN hard? Flaming noobs and raising my post count...

 

New rule in the thread...unless you have an oil sample report, stfu on the whole "synthetics are not good" talk.

 

Good rule.

 

I will be providing mine in the next 2k miles. Started my first run of royal purple on a 5k engine. Already have my test kit from Blackstone

 

I still have like 4 test kit collecting dust ... haha

oil change not due ... didn't even drive much the past 2 months (all on the Mazda3)

 

The only reason I have never had a Renesis engine that has not failed is because I have never owned a Renesis!

 

No joke! There really is zero argument about oils in rotaries anymore. All of the facts are out there and everything has been completely explained. There are NO lingering oil questions at all. None! Some people are just too damned lazy or stubborn to read and half of them that do read apparently lack the mental comprehension to understand what words arranged together to make up a sentence actually mean something. Instead many of these people believe some hourly wage dumbfuck kid at a dealership who only knows how to read a computer monitor or believe a bs tech statement written by a lawyer and an accountant.

The S1 engine failure issues are due to the oil metering system and not the oil used. The oil being used in the car has absolutely no effect on those failures. Why some people are so moronic that they blame the oil brand they are using when they have a problem is about as stupid as blaming their paint when they get in a wreck. It makes no sense. The reality is that ALL S1 Renesis engines get inadequate lubrication to the center of the apex seals. This is not to say that all S1 Renesis engines are going to fail though. Not at all. It does explain why there is a disparity in gas mileage and dyno power measured and also does explain why some engines fail for no apparent reason. This is that apparent reason.

The S2 engines have proper lubrication to the center of the seal and as such don't have the issues that the S1 engines have. Coincedence? I think not!

I know some people are going to say that they premixed, used only 10W40 synthetic oil, changed it every 3000 miles, and still had an engine issue. It happens! Those people were the unfortunate tiny statistic associated with failures that all engines see from time to time.

Now who missed that?

 

I know better keep it that way or you will ruin your record

 

spot on RG.

*sigh*

its funny that people just won't believe the proof, instead they rather trust some dude down the block who probably never seen a Rotary engine in his/her life.

Was talking to my friend the other day, he was talking about the FC that he had (S4 I assumed) abouot 10-12 yrs ago, used, pretty beat up crap.

for some reason it won't idle correctly, burns a lot of oil and some crap he can't remember. he took it to one of his "trusted" garage, the "owners" and "tech" there "told him" it needs a TIMING BELT ... and some other ****, and he paid like 1.1 K for it.

He told me that story couple weeks ago I was like WHHHHHHAAAATTT ? TIMING BELT ? There ain't no ******* Timing belt in a Rotary Engine

He was like ..........

I guess the garage made some pretty good money outa him.

he said about 4 days later they gave him back the car, said "timing belt replaced", but the car still ran like **** (duh), then shortly after he junk yard it and got really piseed about Rotary Engine. of course he never went to that place ever again. but still 1.1K gone.

This is what happens when you put too much "trust" into your local "garage/tech/master tech" guy.



tell me about it.

I guess Im one of the VERY unfortunate ... I mean I got a replacement for free not complaining about that but ... *sob*
