whats the deal with ROYAL PURPLE?

[MZ-Bird]

I have a rotary motor first of all. now RP & a well known rotary performance company say it is OK for the rotary to use synthetic. they escpecially like RP

what is in Royal Purple that is any different than M1 ?

thanks

Not familiar with RP. Never have used it personally but their are some UOA's in that section you could look up. They have one oil in particular that many on here like. Forget which viscosity it was. PepBoys now carries RP btw. RP doesn't offer too much if any benefit over M1, which is so readily available it's hard to pass up.

There are already too many threads here like this. Do a search of these forums using the word "Royal" or "Purple."

It's purple. You like purple? You pay for purple.

Their are too many posts on many things.....like Bror Jace's posts telling people their are too many posts "do a search".

Well guys when you encourage people not to post then you might as well shut down the forum. We can say there are way to many posts on GC and Mobil one. And various other subjects also. How many times can we over analyze mobil one or GC.

Good grief give people a break. Yes the search function is good but maybe a current question would be good. Not a good way to make people feel welcome.

I've been dealing with Royal Purple for years. Very good folks. It so happened, I was one of their first walk-in customers, and they gave me a dealer's discount. The 5-30 hits me for $4.16 a quart. I believe it's Synerlec synthetic additive, does make it better than a lot of others. It's used throughout heavy industry, like nuclear power plants. Places where "pretty good" isn't going to make the grade. Lastly, when I called Amsoil with questions, they were arrogant and short with me. Royal Purple techs talked to me for 25 minutes, and sent me a huge amount of descriptive materials.

 

[MZ-Bird]

OK, sorry I didnt search 1st. I was on my way out the door.

still I dont know what the big deal is on RP...

I meant to type RB as in "Racing Beat" at the 1st of the post.

anyhow, I will search and also call the number that I got from a person about use in Rotary motors.

thanks

MZ,

Man no appologies needed . A guy could search from now till doomsday here and there would not be a RP/Rotary engine topic found .

Instead of posting search search search to new members , might read into their questions first

but ...

As to the question you asked

I'm not certain what RP would have over the Mobil to lube those bearings the rotor shaft runs on . Is your engine injector pump disabled letting you run oil mixed in your fuel by chance ?


Welcome to the site , grab a beer and hang out awhile with us

yes my OMP is still hooked up, I am not running any kind of pre-mix at the moment but neither am I running any type of synthetic.

had been thinking about trying it(RP) lately since Racing Beat states they actually gained a few HP with it and no ill effects.

I used to run Mobile 1 in my 79 & 85 back when nobody did it. I ran the **** out of them but anyhow.

current car is a 90 and it is just slightly moddified. all original motor and when it goes it will get the usual port job and stuff.

I remember when I had my 4.6 I read that the only thing special about RP was it had some additive that gave more HP but also burned off and eventually was nothing special. mind you this was about 8 yrs ago.

I am just wanting to see what is new that I have missed.

I will probably stick with GTX or maybe M1 . I am looking for some of that GC for the next change maybe.

I dont know anything about GC but I am looking

thanks for the help

From what I have read about the Royal Purple it shears real early and thins out. The impression I have gotten is it is a great synthetic, but not for any type of extended OCI. Really is a racers oil.

I agree R/P is more known as a racing/heavy industrial use oil. However, I think the idea that it's daily driver oils aren't top-notch, may be more internet BS.

I asked a R/P rep about this, since I had heard it myself. He said you don't advertise 12K OCI's, if your product can't back it up. Legal insanity.

I would tend to agree. I don't think a company that formulates synthetics for million dollar industry equipment, would drop the ball with your basic motor oil.

There is a lot of information on Royal Purple's Site. Plenty of independent testing by NC State and hot rod magazines. I was about to switch to Amsoil when I came across the Royal Purple info. I changed my mind quick and have been happy ever since. I am so happy with the oil I just inquired about becoming a dealer. We'll see what they say.

 

[Grossomotto]

I like RP Gear Oils like Max Gear. And I know their Race Oils are big amoung the race scene. But, their OTC oils seem to be average. I've seen a few UOAs which are not that impressive.

Their oils do have a place in the market, but I doubt they're taking any business from Mobil, Castrol, etc.

Try it on any topic. You'll get volumes to read ..many hours of reading and still not even touch on your needed info. This isn't like putting D44 & ring & pinion into a jeep forum search engine. Here all the posts span just about every definition available. Unless it's a "vehicle" specific topic or interest ..you are SOL.

 

[PRRPILL]

I am amazed that all of a sudden RP OTC are giving problems. I have used them fo 14 years on an extended basis. I run 15,000 miles with a filter change at 5000 miles. My numbers have always been good.
On this forum the only problem I have seen is with the oil losing a little vis, normally thru fuel dilution. Yet the true test of an oils ability to lubricate, is in it's ability to separate the metals. I have yet to see a BAD example of RP in the wear metals category.
Every time there is a problem with competitive oils and their wear metals, it is the Synthetic solvency cleaning the varnished oils out. Never the oils fault. After all it stayed in spec, vis wise. RP has a natural solvency, yet this is never taken into account on analysis.
We have legions of GC users, all based on one mans love of GC. The fact that the virgin Oil analysis showed 11 ppm iron was ignored. It was of course in grade vis wise, and stayed there, even though it made a lot more metal.
We have a world record for Rotary motors in Australia, David Canitz at the factory races and works with Rotary teams to get longer life.
If you want to talk to someone regarding RP and Rotaries, call David at the factory, or call Racing Beat.
After all, they have experience with it, unlike some of the guru's.

 

[MZ-Bird]

I know Racing Beat uses it and I have read what they said and I also read what RP said about the rotary use. Still there is only a small percentage of people that are using it. lots of doubters.

Like I said , I used to use M1 in my other 2 rotaries and they ran fine.

next change I will try the purple stuff

 

[buster]

PRRPILL makes some good points. You sould have no problems with RP. It's a PAO based oil like Mobil 1. If your that concerned maybe try the Mobil DC Plus Blend or Motorcraft oils.

Prrpll,

I like the maxgear in my wrx 5-speed, but I refuse to pay over $10 a quart from jegs for it. Where can I buy it for less?

 

[sbc350gearhead]

I have no experience with rotory engines, but I do have experience with RP products. I have used RP max-gear, max-EZ, and the api approved "street" oils, and they have all performed perfectly.
