It amazes me how some people so readily dismiss evidence because it wasn't performed on a bench.


Uh...sorry but statistical analysis has been around for quite a few years now. So while you call it "evidence" I call it incomplete information. But that is just how I do things. If you took one engine and ran oil in it for 100,000 miles then took that to any of the auto manufacturers as data...they would laugh at you all the way to the door.

Show me 20-30 of the exact same engines run 2-3million miles under tha exact same conditions and I'll be a believer.

They do state that their 0w40 and 5w40 meets ACEA A2 or A3 which means that they have a minimum HTHS of 3.5 cst @150c.

IIRC, there were two different sets of 4.6 cams run on RP with the virtually the same tear down results. 2-3 different 4.6 cam sets run on M1 with virtually the same tear down results.

Every singly 4.6 I've ever torn down (all run on the API spec oils of the day) looked in line with the M1 cams, never the RP cams. RP did something right there.

did you measure the wear? Tell me you can see microns of wear with your naked eye?

you and john browning the two biggest royal purple bashrs on here. if you followed his post you with out a doubt could see in his pics a clear difference between the cams even with double the miles on the engine running rp. if i remember right he did measure

Those pics are fine as evidence, just not proof.

It just so happens that most people don't seen to understand the difference between evidence and proof, so there's no way to make the point without appearing to dismiss everything categorically.

Don't confuse the scientists doing the research with the pundits using it to spew the nonsense.
 
When you buy Royal Purple, you pay for their expensive marketing. Apparently this works for them as a company that's trying to make money.
 
Your paying for marketing with everything you buy. Whats the difference?

The amount you pay per product. Much higher with RP. Same goes to FRAM
 
All this recent talk of RP has me thinking of trying it sometime. It's an "underdog" that just might be a good oil.

It is a good oil,there's alot of people I know who used nothing but RP and have had no issues,complaints etc etc. On on a oil forum, you find the haters,kinda funny if you ask me

I find it locally for less than $.50 more per qt. than M1 and less than CE. Whats the big deal in spending a few more $$$$ ????

Correct. RP just won't get a break here. Misinformation and unfounded bias abounds regarding RP. It's really one fine oil. Tune out the hatin' and believe the truth!

RP most definitely is an extended drain interval capable oil. RP says 12K and I have seen UOA's on it to 15K with more life left. That qualifies it as an EOCI oil. I have personally run it past 12K and it was fine.

How can you make such a claim, ANY claims really, when by your own admission you have never run it? You are amazing. You have taken over the top seat as the RP Bashing King on BITOG, beating it down in every thread that comes up, yet you haven't ever used it. Do you think you have ANY credibility in doing so? How about you start each trashing response with the disclaimer - "I have never used RP". At least that way new folks here won't take your uninformed and bogus claims and statements serious.

I am also curious what has your under garments so bunched up against it? If you haven't used it, so you have no factual and personal experience to go on, how can you trash it so? You must be really bored to take up such a vendetta against a product you haven't used. Other than saying you think it is too expensive, which I have shown time and again in response to that claim by you it is no more so than any synthetic if you shop( I pay less for it by the qt bottle than M1, PP, VVL, QS, etc... ), your comments are all based on what others say. Nothing from your own experience.

ZERO credibility on RP for you.

I have always been very clear with the fact that Royal Purple isnot a bad oil it is just far too expensive when it returns results no better then Mobil-1,PP,RTS 5W40,Amoil and Redline which are all cheaper then ROyal Purple!!!! TYpicaly their Race Oil's are on par with Amsoils and Redlines regular non race oils but again they often cost $3-$6 more per quart then either Redline or Amsoil.

With reguard to their Gear oils well lets just say they do not hold up to extremes like Redline or Amsoil gear lubes and their various MTL like products are absolutely worthless. I tried them and in my TOyota they lost their cold weather performance by 10,000 miles which in a cold state with long winters like MIchigan has is unacceptable of a premium priced synthetic lubricant.By comparison I get about 40,000 miles of excellent cold weather shift performance with Redline products before I start to experience a subtly degradation in shift fell ans such.

I actually find it repulsive that I cannot buy a Hot ROd,Mopar,4X4 magazine or watch anything on SPEED Channel or SPike TV with out having to listen to people with less oil knowledge then my 11 year old son push Royal Purple Products every chance they get!

I can live with the shearing of their oils even though I think it is odd that any synthetic 5W30 would shear that badly but I do demand a price that is inline with the performance of the product! I am not the type make purchase's based on marketing and fad's with in a sub-culture. THe only reason I spend the premium money on Redline gear oil is because it offer's me performance that I can not get from OTC products so the premium price is due to added value not because I am paying for agressive marketing plan! I do not pay the premium for their motor oils because I do not need a POE synthetic with beefy additive package to go 6 months or 10K miles OTC oils that are far cheaper can do this.

So while this site is subject to much hype German Castrol,Penzoil Platnium etc........FOr the most part few people on the site are the types to just toss money to the wind. Many are frugal and with out much more drastic performance difference between RP and other cheaper synthetics not a lot are going to go googoogaa gaa over it!PP was for a long time dirt cheap and it offered sludge cleaning as an added value. M1 0W40 also ofer's sludge cleaning as an added value but M1 onlymentiones it on their sight not on the side of the bottle.

Marketing hype is one thing we are more immune to on this sight. Not so much these days as the number of professionals in the field of tribology,chemistry, or automotive industry has dropped and more and more average Joe's have joined up. Marketing is for those that do not and will not seek out technical information to make non-emotional decision on purchase's! I hate front wheel drive cars and I hate 4 cylinders in car's but I am driving a front wheel drive Camry with a 4 cylinder because that was the practical thing to buy since I got it with everything but a Sunroof and mag wheels for $17,000 brand new with 4 miles on it.Had I bought what I wanted I would have a 4Runner or FJ Cruiser in the parking lot right now!Same thing or same type of non-emotional reasoning is how I pick most lubricants. A combination of utility, cost and any value added.


There is no way to say that PP, M1, etc... return equal to or better results than RP( or vice versa )in any given engine unless you have run them to compare. Every engine responds different to different oils. So your comments that RP will return no better results than those other oils are wrong on their face.

In general they also do not hold any credibility either. If you just lined up RP, PP, M1, Amsoil, Redline, QS, Schaeffers, etc... and had to pick an oil to start out with based solely on how they were made( base stocks, additive pack, final spec's, etc... - you know, all that techincal info you claim to research and check out ), RP would be much higher on peoples lists( that don't have biases )than the likes of PP, QS, M1, etc... It is a premium synthetic not a mid grade synthetic. I am not bashing those other oils either just stating a simple truth.

RP ranks with the premium brand synthetics like Amsoil, Redline, and Schaeffers. It is not a PP, M1, QS, etc... type oil. On a 5-7K OCI PP, M1, QS, etc... do just fine. Even out to as much as 10K they will do fine. It isn't that they can't do a good job. For most folks the premium synthetics are overkill. However, don't say RP can not return results that make the higher cost worth it. I have 20 years using it saying you are full of it with such comments. How long and how many times have you run Royal Purple in ANYTHING other than the one use in the Toyota? HAVE you EVER run Royal Purple oil? You sound like a parrot of the haters on here that haven't used RP yet love to tell everyone how bad it is. Not a good way to go if you wish any credibility in your posts just FYI.

As to your comments about cost( is this PT1 under a different username? )here is a little info for you so just maybe you can get your facts straight. "IF" you take some time and shop around for RP products they can be purchased for the same or even less than those cheaper brands you talk of. Also, Redline costs a LOT more than RP as a rule. Redline is probably the most expensive oil/fluid out there at least where I have seen prices and I have looked. Redline is great stuff and I have used it but it is always more than RP when I price it and by a large margin at that.

I am not the only one to say this either as others have backed me up( ie; RP for the same or less than name brands ). While I agree that some national chains sell it for too high a price it does not sell for that everywhere. I will use my local prices for RP oils( normal weights = 5W-20/5W-30/10W-30 )as an example...

ROYAL PURPLE:
Parts Stores = $8.99-$9.99 p/qt ( too high I agree - FOR ANY OIL THOUGH ).
Wal-Mart = $8.47 p/qt( still too high )
Coastal Customs Speed Shop - $7 p/qt( exactly $7 - my 2nd source )
R&D Speed Shop = $5.75-$6.50 p/qt ( this is my regular source - price depends on how long I can give him to order it - depends on what warehouse he gets it at and his ordering schedule )

PP, M1, QS, VVL, ETC..:
Parts Stores = $5.50-$6.99 p/qt( depends on what store - including Wal-Mart - and what oil )

So as you can see I can get RP for the same or even less p/qt than the name brand "cheaper" oils you say are a better value because RP costs too much. If you want to talk gear oil I just got some RP MaxGear to do the front( 75W-90 )and rear( 75W-140 )diff's in my 08 Ram and paid $10.95 p/qt( up from the $9.75 I paid last year ). Would cost me more to walk into a parts store and get M1 synthetic gear oil in those weights. I don't know about Wal-Mart pricing? Last time I bought some MaxATF tranny fluid it was $9 a bottle but that was not at my best price option so not sure what it would be?

RP's Race Oils are on par with Redline and Amsoil's non race oils? WHAT??? You just have NO CLUE! Please think before you post. Don't try and compare a racing oil with regular oils as it is just ridiculous. RP's XPR race oil has no comparison to Amsoil's street oils. Maybe some with Redline. The RP regular oil is every bit as good as any Amsoil product and holds it's own with Redline.

Your gear oil comments saying RP Maxgear does not hold up the way Redline and Amsoil do is another huge pile of you know what. If MaxGear failed in your Toyota by 10K something happened not fluid related. The cheapest dino gear oil can go 10K. I live in NH and it is just as cold here as it is in MI. I have run RP gear oils since the early 90's and they have performed great. MaxGear is one of the absolutel best gear oils on the market. I see a shift comment so do you mean you used their manual tranny fluid? Their Synchromax fluid is highly regarded in all circles as an excellent product for MT's. It is possible your tranny did not like it but just as with oils each application is different. To say it is [censored] because it failed in your application however, and label all their gear oil/MT fluids as poor, is unjust and just crazy.

Another person claiming RP oils shear all the time. That is such complete and utter hogwash it is not even funny anymore. Please go and get proof of that and post it. I don't care where you get it either. Here or other sites. Just back up ONE thing you RP bashers say with actual proof for ONCE! 1 or 2 UOA's showing a sheared 5W-30 does not mean all their oils shear or that the 5W-30 is prone to it either. You need a lot of UOA's showing that to come up with a consistant pattern proving it and you will NOT find that here. The RP UOA's have been looked at on this site and they do not back that up or the other common bashing points. What they show is RP is an excellent performer with a few bad UOA's like ALL oils produce. As I have said, and most fair minded folks here agree, there is no one oil that will do the best for each application and no oil is as bad as some make it out to be. Alsao on some of those shearing cases found here there were other causes behind it like fuel dillution. RP oils are not shear prone nor to dangerous levels. Not 5W-30 nor any other weight. Get over that complete bull please. That is as lame as saying it is Grp III.

You talk of the marketing gimmicks and how it repulses you with RP and then you talk of PP and M1 with their sludge cleaning. Ha what a laugh. ANY quality synthetic oil will clean out sludge and deposits. To claim superior sludge cleaning is a MARKETING PLOY! Why does that not repulse you?

You in fact do not buy products based on performance vs cost as you claim. Well, maybe you do BUT you clearly have been drinking the anti RP cool aide and have fallen victim to the unfounded and bogus claims made here by a certain group of posters with an agenda. You 100% are biased against RP and do not give it a fair shake. You mouth too many key bashing points to have actually used it yourself other than the time in the Toyota. You are far from biased and unemotional when you talk of RP. You have your mind made up based on the rantings of the haters and you do not research RP at all or you would see it is a quality product.

You have clearly fallen victim to the BITOG RP Bashing Marketing Strategy!
