Royal Purple seems to be a divisive issue around here. I want to know if anybody has seen the above article before or if it's been posted here before and dealt with. It seems to be a valid test but perhaps there are things I am missing. Not trying to get into a [censored] contest just want some honest feedback regarding the test and its results.
Love the forum and the banter. So far have learned a lot from the sticky's and some of the knowledge of the posters!
 
Old.

Been posted here before.

Been ripped to shreds.

Been retracted by the magazine.

Then someone finds it again, as though for the first time, and makes a post just like yours asking for opinions. Lather, rinse, repeat...
 
so was it a planted story by RP? Didn't know it was retracted by the mag. Interesting. Thank You for the reply!
 
The test is only valid for that machine and the results are very operator dependent.

If you're going to use oil inside your engine then this test will not help. Your engine runs at higher temperatures and pressures and in many cases he oil is under pressure and actually flows through the bearing or friction area. And there are usually no bearings that are mounted across each other that are pushed together like that.

I don't think that one test no matter what it might be can represent the conditions that engine oil is exposed to day in and day out. It's not that simple.

Basically this test is a scam. It's something you would expect to see and the local county agricultural fair.

Well put.

The only way to test an oil properly is to run it in an engine. It's that simple. 4 ball tests,one armed bandits and so on are a joke. They carry weight only to folks who know nothing about what they are seeing. L basically a scam.
Rp makes a great product. I like them. I don't like the price.
There was a day when boutique oils held an edge over what was available to consumers however today that line has been crossed and is erased.
When jugs of castrol and m1 euro can be had for 25 bucks a piece only a fool spends more.
Now if I could get rp euro for that price I'd be using it. For me it's about dollars and sense. As in spending more dollars for no extra gain makes no sense

This is too hash.

Someone may like the purple color of the bottle and he/she sleeps well thinking about beautiful bottle color they just bought.

I never tried Royal Purple anything, but I hear that their transmission and gear fluid are very good. But I think Amsoil are better.
 
Too expensive but a good oil. Not any better than pp or pu or mobile 1 etc from what I can tell from uoas I've seen.you gotta judge by multiple uoas to even get an idea of an oils quality.i used the oe version once apon a time in a mazda seemed fine but didn't uoa it or anything.their30 weights seem to follow a pattern of shearing down out grade rather early and then thickening right back up while their 20 weights thicken out of grade and stay

Don't know if it was planted by RP. The machine in the article has been used by other companies to advertise their stuff, so maybe the mag just thought it'd be a cool thing to do. But yeah, it's bunk.
 
What does get me to thinking about this test is that Pennzoil and Valvoline always have near perfect UOA's,always produce "smooth and quiet" running engines,and they beat every oil in this test (except the RP and Penrite 5W60 which they almost tied with). As I've heard people here say this test does in fact coincide with gear oil quality,makes me wonder if Valvoline Durablend gear oil would be a great choice in a rear diff?

Who knows though huh! :^P
 
In order to sell oil at higher than "big guys" prices it either has to be better, or "different". Who's got the biggest R&D department. Who's been around since the dawn of "lubrication products"? Who's purple?

No. Different pressures, different flow, sometimes under pressure in a real engine, different temperatures and again there are no shafts or bearings aligned across each other.

Choosing an oil based on a test like this is about as valid as choosing an oil because you like the company logo.
 
The only thing Royal Purple has going for it is the purple. I'd like to have the money that has been spent on mouse milks related to those types of machines.
 
Yeah, tests like that are bogus. But that doesn't mean the oil isn't good; it just means the test itself isn't good.

IIRC, SN rated RP looks similar to Valvoline on PQIA.

I'm only using RP HMX right now because I just wanted to give it a try. Not to mention, I've heard good things here before about Synerlec.

Of course I'm not going to say that I think RP HMX is any better than another HM oil. I'll leave the legitimate testing up to those who know what they're doing.

That's why I'm not brand loyal. I just like to try different brands sometimes for the sake of it. My truck will run on nearly anything. Is it a waste for me to spend 40 bucks on HMX when I could spend 20 bucks for plenty of other, just as capable oils (for my 5.4L Triton)? Maybe. But it's my money, and I love oil, and I love changing oil. And I love doing what "floats my boat" because it's fun.

And hey, that purple color is just gorgeous. I really can't think of any other jug more appealing than this...

Exactly. I like RP. However, I'm not interested how it fares on a one armed bandit nor what it looks like if you barbeque it for three hours in a petri dish.

As for jug aesthetics, I actually prefer the HPS ones, myself.
