Interesting.

What is this belief based on?

I have tried Castrol Edge 5w40 and Mobil 1 0w40 and both used a quart per 10k OCIs. With RP there is no oil usage. Plus I like the fact that RP has a PAO base with a very stout add pack.


Is Edge 5w40 approved for your Audi?

Edge 0w40 is superior, has more approvals and is PAO.

Yes Edge 5w40 is VW/Audi approved.
 
Id personally use whichever (cheapest) oil meets the Audi spec. The only difference will be in your wallet.

I agree ... I'm sure that Royal Purple is an excellent motor oil, but I recently came to the conclusion that as long as the oil meets what the owner's manual specs for my car, I wouldn't have any problem using it. I used to not consider store brand motor oils, but that is no longer the case. I recently bought some NAPA conventional motor oil (which is made by Ashland/Valvoline), and I plan to buy some NAPA Synthetic when it goes back on sale. In fact, NAPA and Chevron Havoline are what I plan to use most of the time after I use up the other brands in my stash. I would buy other brands/store brands though if they are at a lower price.

I understan what you are saying. Royal Purple techs tell me that it is PAO base. Until someone does an independant test to prove otherwise I'll take their word for it. I dont put too much emphasis on PDS data sheets because those are just numbers that people extrapolate here on BITOG but at the end of the day all those extrapolation/discussion are merely all opinion based.

Independent test's show it has inferior virgin performance both hot and cold than average synthetics in the same grade.

Supertech from Walmart has tested better in VOA's and we know it is not PAO based.

Yet reps from Calumet claim their product is PAO based. Something does not add up.
 
I dont put too much emphasis on those numbers. They honestly dont tell me a thing about whether the basestock is Grp III or PAO.

Compare PAO, Viscom, and XHVI and pay close attention to extreme cold performance. PAO has quite an significant advantage over even high end Group III in extreme cold.

Notice the straight grade RP has no where near the performance nor the VII of virgin PAO. Either RP API is not a PAO based PCMO or the additive and other base oils significantly degrade PAO's performance.

What would you do if a new basestock was invented? Stay loyal to PAO or go with the new kid on the block?

Go with the better base stock.

Dave, would that indicate that it's a "subtractive", rather than an additive ?
 
What? Yes they do.

Wow,

This is ridiculous, Royal Purple is part group IV, of course its more expensive, so is Mobil 1 Extended Performance.
The marketing for RP is based on car fanatic and performance.

It is a very good oil, no doubt. Why would people put cheap oil in their car that thay paid thousands of dollars.
To me, its ridiculous, stupid and ignorent.

If you can get RP at a good price, why not give it a shot? It cant be worse than PP, with the "new" pure plus marketing hipe, if its that ure and that good, why is it so cheap?

To me, RP is a well reputated product, like Redline and M1.
Plus, its made in USA.

If i could, I would you RP for my next oc, way over any other product.

No they don't. You can have many different grades of oil made from PAO. You think they are all going to look the same in a VOA? Not even close.

The only ridiculous thing is users taking stock and believing the gospel from an royal purple marketing rep on facebook that posted royal purple is a PAO based lubricant. Walmart Supertech has superior Pumping Viscosities specs and it is not PAO based.

Yet people just have to believe the marketing from a company that publishes the following testimonial as a part of its marketing campaign.

thought motor oil was motor oil ’till I saw an auto show that talked about Royal Purple. I put it in my slightly modified 2002 Camaro and it made a very noticeable difference!! ...Your oil has smoothed it out COMPLETELY!!!!

No more idling all over the place for the first 10 minutes. It’s smooth sailing from the get-go.

Way to go guys!!

And advertise this

Superior corrosion protection

No rust observed in standard industry testing. (I hope so.)

We recommend up to 12 months or 12,000 miles when using Royal Purple. (Notice up to I bet how does Calumet determine up to? What if a engine seizes after 10 months and 10K OCI's will Calumet honor the claim because there is an out clause of "up to"? All of this sounds like a snake oil additive company and its testimonials on late night television.)

I am done on this thread until someone is able to post something other than believe.

Ok then give me documentation that says proof positive that if a value of say VIIs are within certain ranges then the basestock is PAO or POE or Grp III. Same goes for MRV, CCS, VI and so one. Evertime the numbers are mentioned here on BITOG everone SPECULATES that if they are certain numbers and since they look so good on paper then it has to be PAO and not Grp III or vice versa. I'll wait patiently for you to give me a link that proves that. Believe me you wont because I have scoured every SAE paper out there and havent found a definitive answer.

See the funny thing about people who love or hate Royal Purple is categorized in two ways. People who love Royal Purple usually love it because they are gear heads who use Royal Purple in their modified racing engines and then after a couple of years open up an engine and marvel at how well the components look and how little to no wear there is. I belong in this category. I own a very reputable speed shop and have torn down many an engine running on Royal Purple and every single time there is little to no wear. Of all the engines torn down and all the various oils used all my mechanics unequivocally agrees that Royal Purple tends to protect the best. This conclusion is not based just on visual inspection but also careful measurements of components before and after.

The second type of people are those who have never given Royal Purple a fair shot and bad mouth them from what they read on the internet and want to conclude that an oil is not top tier oil because the so called "numbers" are inferior to some cheap alternative. Better yet they read used oil analysis here and split hairs about how it has more wear than other oils in different applications.

Thank you for the links and numbers. As insightful as they may be I elect to use Royal Purple because my "real world" experience has shown it to be a top notch and the finest out there. Tearing open over 100's of engines run on Royal Purple and the results speak for themselves.
 
Problem is that people who love Royal Purple categorise anyone who doesn't as a hater.

Got any pics ?

It's an unusual career combination, speed shop and pharmacist
 
Not at all, that wasn't my point.

Is it possible to achieve a -50 degree pour point with Group III?

Read it again. You completely missed it. PAO doesn't produce static numbers. There isn't just one type/grade of PAO.
 
Ahh, yes of course there is. And I knew that too.

Sorry, backing off...
