....science!

Why is this stupid debate/debacle over syn oil vs Dino oil?. Wow. Do some research on your own and make a decision based on your own research ?. I am switching to Syn from Dino oil this week end and hitting the emissions station here in Colorado. I am going to post my experience with Syn oil(Royal Purple) and I did research royal purple on many sources. I am not going to ramble about my research because it would serve no real purpose, do your own research and make your own decision.

I thougt it would be cool to post the experience I have with Syn oil vs Dino oil. To set the post my rx8 is a 2004 automatic with 79,000 miles on it. I have changed my Dino oil every 2000 miles like clock work(I am retired and can afford time with the car). I am switching to Royal Purple Syn 5w-30 in the engine, Royal Purple 75w-90 in the Differential and Royal Purple for the transmission and we shall see how it goes.

For me I often say owning the 8 is like my Harley and I mean it is a mind set owning a rx8 because it isn't a daily driver, it is a specialty car that is fun to drive. A lot of 8 owners probably should have bought a Honda, no slant on Honda, but its not an 8.

^ smh ...

Hey, if it's science, it's testable. Supply me a dozen women for the summer and I'll check it out. :rofl:

^^ And what type of lube will you be using ? Dino, Synth or KY ? :)

Before you put royal P in your car you should really check out how it held up to the UAO test thread. Many other brands did better. I was actually surprised at the findings since the owner of RP is a old rotor head like us.

I will just say if you are dead set on using RP test it out with blackstone then do a side by side with M1-0W40 or a few other well liked brands and let us know your findings.

Also I own two hondas as well as my two RXs your last comment is like calling all people who drive Japanese cars ricers. :(

Presumably Poacher's final data set will prove or disprove that...so we won't have to rely on actual knowledge in the future. :)

i doubt we will find anything,,,, he has yet to post a response

Failed thread

Data in and of it self is highly political d can cast the shadow needed and the issue with data is that there is always data to the point on both sides of the issue.

What if I post my experience with syn oil, it isn't a dead thread , unless of course time going by with syn oil in my 8 and nothing negative happens doesn't count?.

@hoss-05: I have been doing my own research on both sides of the Dino/syn debacle and my decision is to go with syn. I am currently running rp and at 2000 miles I will dump it and try another syn oil, after I have satisfied my self of that brand. I will post the noticed results. So far with rp I have noticed easier starts and a better idle in drive.

I am retired and have time and money to play , so may be I can make a mistake you can't?. After years with Harleys all custom Harleys I learned that its ok to f*&k some thing up just learn from it. I am not worried about syn oil. I have researched to my satisfaction. I am not een going to attempt to get you to believe what I found and from whom, because at the end of the day all that would serve to do is keep the debacle going. I searched, I made a decision, shit brakes, go have fun.

^ since you are retired and have 'time and money' ... i suggest grabbing yourself a dictionary and a good book on the English language. Yikes...

Seeing the data wouldn't be a bad thing. I think, as a community, we've gotten away from encouraging people to participate with data regarding various topics because the matter is considered "settled".

There is one major aspect with the debate on mineral oil vs. synthetic and that is the API standards that the vast majority of oils (at least sold in the US) are put through. The most recent changes subject oils to conditions that shouldn't ever be seen with a car and certainly not for the time intervals they are tested at.

This goes to the earlier theory that as long as you have an oil which maintains the expected viscosity, you're going to be ok.

About the only reason I run more expensive group V oils these days is because I like the Ester base oil properties. I've gotten away with running Group IV stuff for a lot of miles and so far had two engine teardowns (one over 100,000) where the bearings were in pretty good shape for a motor of that mileage.

That said, the problem with such testing is the conclusions will only apply to a small subset of individuals, if indeed anyone at all. To produce scientific results, you have to have strict tests which defy how nearly everyone maintains their vehicles. Anyone with a rigid maintenance schedule tight enough to fit the bill probably sleeps in a padded cell.

After all the research and discussion I've had, it came down to this: If you prefer to change your oil often, use a lower priced Group III mineral oil. If you prefer longer change intervals, or have serious concerns about leaving up to 1/3 of the used oil in the oil system then look into the Group IV or Group V base stuff.

Bring on the research, but because of the wide range of operation I don't know if we can come to any solid conclusions.

Nice idea, putting the Syn to Mineral oil debate to bed, but impossible. Oil is not a standard item. Taking one or two, or twenty different oils and attempting to make overall judgements is simply impossibly difficult for so many reasons.

One big problem is how oil is rated. Companies make oil to meet those standards, but that is only part of any oils particular properties. Let's take an analogy for oil and how it is rated... like a dating standard for women. Let's call it the SDA 40 (Standard Dating Attributes) standard. SDA 40 dictates women must be 5'6" or taller, weigh under 150lbs, and be under 40 yrs old, and not break down under stressful conditions or doing hard work for 30 minutes or longer. But the SDA 40 standard is obviously flawed in too many ways to count. Although it says something, it misses more than it clarifies. Many would protest that is NOT a good standard for THEM, and THEIR needs in women. IOW what it DOESN'T take into account is myriad... and so with oil in general or oil in particular for use in the rotary.

Even Mazda's recommendation don't work all that well, as evidenced by their continuing change in lube techniques, not to mention lube related engine failure modes.

The point is that any synthetic oil and any mineral oil meeting the same 'standard' says something, but in truth leaves out much. Most every in-use property of oil - viscosity, shear properties, flow rate, etc., is a multi-vector variable over e.g., temperature, severity of use, and type of lubrication required, etc. The best that can ever be produced in some multi-million dollar study that will never happen would be to produce statistical probabilities regarding some oil that meets some standard on some varied group of cars doing various things under various conditions. IOW not very useful to anyone in particular for their car.

Nevertheless ... :beer: on with it... :) it's all good fun.

Still waiting for this so called "Data" to arrive :suspect:

Unitll then this thread provides no positive contribution and is another redundant oil thread similar to the other hundred already open, except some of those really do have "Data" :scratchhe

@paimon.soror: Why r u always finding some thing to focus on beside the thread. Where u treated alright as a kid or r u still one?. There is no political currency for your stupid remarks and pointing out some ones English grammer. We are talking about oil here stud. Grow up and stay on point(OIL):).

If any one here feeds on ridiculeon a public forum like you do, well in my opinion you deserve each other. I may not have a higher education, but F U for being the bully you are for trying to gain hollow popularity from it, that make you a punk ass bully , not the behavior of an highly educated man. If you can't resist being a bully, go find another forum for highly educated folk like u.

" I always wanted to be an inganeer and now I r one".

Its been like a week. If he came up with a ton of data in a week, I would question how quickly its been acquired and if that affects the datas reliability. C'mon now. this is Science.

Yeah I remember that one Mazda commercial on T.V. a few years back. They showed the 8 taking some nice turns, gave some of the specs, and then said "F*** you if you think you're gonna drive this to your work and back. Unacceptable, go buy a Honda".

I think at the end of the day and even though we have some self appointed gods here, it is up to each of us to research to the best of our ability and make decisions based on that because Data isn't the end all of any argument because Data is interpretive . There are other points beside just Data. I like the attitude of " IT's all good fun".

@Paimon.soror: Quit messing with me and being a distraction to this thread. Grow up son.

This work will take me some time to accomplish. As this is not an official project; I can only work on it during my "free" time. Additionally, I don't have multiple decades worth of experience running tandem MS, gas chrom, and the like. So it can easily take me a week or more to validate one analytical procedure. However, once I have validated the procedures, I should be able to run the samples and get the numbers in a few days - provided I don't have to do too much trouble shooting with the equipment along the way.

While you're working on the oil tests, I'll help in any way I can with the SDA 40 tests.

Ken

Well if it makes any difference, I have an 04' MT 6port and have been running M1 5-20 for 20k miles and have recently switched to Rotella T6 20-50 and have not only increased MPG's by 1.1 but seems like I burn less oil. Every 50 miles I would add onto to the M1 and every 65-70 I would add onto the T6. Maybe a trial you can look into.

@hoss-05: Good suggestion on the side by side compare. I am on 1000 miles on the rp and at 2000 miles I will try another brand after I research that brand and post things like , what I saw in the rp and what it smelled like. When I drain any oil I have a glass high side baking dish I catch the oil in and examine the oil after it has settled for a day.

Actually my comment about the Honda is really a good one , simply meaning "Buy a Honda because they are more dependable than the 8 with little to no maint and beside if I were calling people who own Honda's ricer's , I guess I am one as well because last time I checked Mazda rx8 is a Jap car?:):)lol.

thx for the adult input. I will post results . I am on 1000 miles on the rp and next I will probably research AMSoil and I will post why I rejected or excepted it. My goal is to find the oil I really trust and has treated my motor right, that is why posting data to feed my point of view is nothing more than a data pissing contest because data is so interpretive .This is for me an interesting test because my 8 has 78,000 miles on it all dino oil at 2000 mile oil changes. Anh who thx for the input.

Yes, much can be learned by examining oil in a glass dish :wallbash:

lol i love reading his posts.

He is obviously bored in his retirement

Same :rollingla

we have the viscosity data from DUA thread thanks to 9krpm, that data could be compiled and graphed.

the next set is burning, someone should setup a test rig that burns oil in a engine like environment and see how much is left from each kind of oil.
