Royal purple

The mechanics at a former power plant I worked at swore by RP. Used it in the boiler feed pumps. I do recall making rounds one shift & noticed a mechanical seal failed on the outboard side of a boiler feed pump. Went back to the control room and swapped feed pumps before the in service unit completely failed. Once I swapped pumps & placed a clearance on the one with the failed mechanical seal I noticed the oil reservoir was at least 90% water. I was surprised when it was torn apart the outboard bearing was still in good condition.

I'm not saying it would have lasted like that for long but figured with a 90/10 water/oil mixture in the oil reservoir that bearing would have been toast. It's also very possible that mechanical seal had let go just prior to me walking out to start my rounds on the unit.

Besides that facility, I've never used RP products in any of my equipment
That’s right up there with hitting a rock and driving with no oil.

My ex brother in law works for a billion dollar pump company, twin screw pumps........for many things but mainly high viscous fluids like oil ......he said they spec RP in their units.

This one was a stacked centrifugal, 2800psi. The feedwater was already about 190* being pulled from the tank prior to sending to the HRSG.

yeah i am not a pump guy, but saw a 6 million dollar quote for a pump build, with barrels of an RP commercial product. twin screw will move water, but not like centrifugal per dollar. centrifugal will not move oil to good.
 
Hey everyone simple enough question that will probably end up being complex. How does royal purple compare to other major players? I have spoken to their tech line before about gear oil. They were super helpful and personable. I've used their gear oil and their synchromax. I haven't used their engine oil but am curious how it compares. I've read elsewhere that it's basically Valvoline with purple dye. Is there any truth to that? Not trying to compare pricing or any of that just want to compare the actual technical performance compare to it's counter parts.
It's all I run in my Mazda rx-7 race car along with their gear oil.
 
That is not what he is saying.........he is saying it is a fairy tale.
Did not say it was a fairy tale.

A gear box filled with 90% water and an engine drained of oil and still operating are both extremely harsh environments and similar in scope. Whether it was due to the brand of oil is not determined however, since no corresponding catastrophic test was performed with a different oil.

Well it did happen & from my understanding was the reason the mechanics swore by it.

I'm not sure what type of RP oil they were using/ordering for the pumps though either. Operators just filled from a dispenser hose in the shop to a handheld container to top off any equipment we noticed was low on rounds.

People can believe what they want. I know that prior to that experience I would have thought it would be bs as well but just happened to experience it firsthand.

Yeah I feel you. Personal experience is all I have also.

Oh I get it. But you are coming from a point where the lube "could not have been" the cause or lack of cause since their was no tests to conclude otherwise, when if fact the only lube that was used was the one in question.

No, you have said in the past in similar posts and stories shared by other posters, including me, that "this is an extrapolation of out observed outcomes where the observer did not know what they were observing", absurd.

Basically saying that they are not smart enough or with understanding enough on a subject to comment on it.

And the result of which is a fishing story.

The old stories of hitting a rock and draining the oil yet the engine keeps running are as old as motor oil itself.
This is a clear opinion based off of no fact whatsoever, since you of course have not been around since the beginning of oil itself, and could not possibly know the validity of the "Old stories".

So a fairy tale indeed.
 
Nothing to do with the question at hand, but it seems to have been forgotten that without Royal Purple there would be no BITOG forums. The original Bob was a Royal Purple rep and he started this site. Seems like for that reason alone RP might rate a shade more respect around here.

Bob was a Shaeffer oil rep if I remember correctly. Good stuff.

 
Someone will correct me if I’m wrong. I believe RP does have a high end offering of majority group 4/5. Not the stuff at Wally.
Yes the HPS and XPR. XPR is $17/qt. They do mention high solvency in their PDS and their oils do appear to clean very well. Calumet owns them.
