Royal Purple

[rage557]

Hey all I'm looking for some testimonials about Royal Purple. I just got a case of it in and after searching the forum I found some who liked it and others who said they would say away but no real info/stories on it. From what I've heard/read it is really good.

If you've used it or heard things let me know. I don't want to put garbage in my engine. Any engines blow up? Anybody notice performance changes? Let me know.

Royal Purple compares to Mobil 1, they are mostly equal.

And Mobil 1 is OK for street/strip car but is defenetly NOT racing oil. The bes oil out there will mosltly be MOTUL.

If you want the best of the best go Motul $$$ otherwise Mobil 1 or Royal Purp should be just fine....

First read this: www.wihandyman.com/forum/showthread.php?t=13295

Then read this: https://www.caranddriver.com/article...rticle_id=3631

Now you'll know what it means that Mobil 1 is derived from polyalphaolefin (PAO), a Group IV base stock and Red Line and some types of Motul are derived from Polyol ester, a Group V base stock. All three websites clearly state the constituent base stocks of their oils and consequently all three of the above brands can be considered true synthetic oils.

Now go to any Royal Purple website. Although the oil is referred to as synthetic, NOWHERE is the base stock from which RP is derived, specified. You will find all kinds of verbiage claiming Royal Purple's superiority to every other conceivable oil and that's about it.

Finally, go to http://www.coximport.com/royalpurple/faq.html

Look for the following question: If Royal Purple street products are not 100% synthetic, why are they priced similar to a full synthetic?

Now read the answer: The Synerlec technology provides the best protection and performance increases available, however, it is very expensive. We have blended our street oils to exceed the performance characteristics of any other blended or "Full" synthetic. If having a full synthetic is important, we have our racing line which can be considered a "Full" synthetic.

So RP admits that their oil is not a true synthetic in the sense that it is not engineered from synthesized hydrocarbons derived from either Groups IV or V base stocks. In fact, it is probably a hydrocracked Group III petroleum-based oil (perhaps similar to Castrol Syntec?). Also note that "synerlec technology " is never explained in any meaningful way.

RP may be a good quality engine oil but it is NOT a true synthetic. Why would anyone pay a premium price for this oil, when true synthetics can be bought at similar prices. Also ask yourself what it means to say, "we have our racing line which can be considered a "Full" synthetic."?

Happy Motoring!

Actually Royal Purple can't be compared to Mobil 1 and they are definitely NOT equal as one is synthetic and the other is not.

Some types of Motul are ester-based, as is Red Line, so I would imagine they're quite similar. IMO, although I personally prefer an ester-based oil to a PAO-based oil for theoretical reasons, you can't go wrong with Mobil1, Amsoil, Red Line or Motul as all are fully synthetic oils with all the advantages inherent in that type.

So basicly RP is a high quality non sythetic oil. Thats good to know. Anybody had any experiance with increased engine wear do to using it? I have heard of people using it then having their engine die.

goldstar you are my oil god

Perhaps with goldstar's clarification you should stay away from RP and go straight to Mobil 1, Amsoil or Redline, Motul if you have the $

Notice I said that Royal Purple MAY be a high quality oil. I really don't know one way or the other. I just recalled that TheMAN had discussed RP oil and mentioned that it was implicated in a number of cases where its usage caused severe engine damage, and a number of law suits had been brought against the company as a consequence. Based on what TheMAN had to say, I would definitely advise against the use of RP. You can read more about his comments in reference to RP and synthetic oils in general by searching for a thread titled, "Mobil 1 Horse****" on the msprotege Forum. It's a worthwhile read.

Happy Motoring!

hmm, well i remember watching a show on speedtv, they compared two different engine oils, Royal Purple and another expensive well known company that i cant remember. anyways, they werent testing the lubrication, they were testing the heat loss. and Royal Purple did noticably better than this other oil, it was around 15-20 degrees.

i also told this one guy that i met up with at an autowreckers that was running the gtx swap with standalone and 15psi WHO WAS RUNNING A STOCK RAD!! to try royal purple because his engine likes to run really hot. so i guess he did because when i saw him about 3 weeks ago he said his car was running a lot cooler and he could feel the power gain from brushing all that heat off.

Meh..too expensive. I'll stick to my Castrol Syntec. I've laid the proverbial smackdown on my engine with Castrol in it, and it keeps comin back for more...

Well I've got a case of rp in my garage. I have not modified the engine yet so I figure I'll be the guinny pig. It goes in tonight! I'll post any noticeable differences.

That comment about using RP was directed to Gen1GT, not to you. In any case, good luck with your "experiment."
