Absolute BULL PUCKEY to the highest degree.

I tried to steer clear of this thread because trying to reason with the RP bashers on this site is like beating your head against a wall or trying to stop the tide from rising. Enough is enough though. I am going to respond to the quote above and some of the other stuff said in this thread.

So many people here make these type of ludicrous claims about all this so called "proof" that RP is so bad yet where is it? I have run it since 1990 in daily drivers, hot rods, muscle cars, motorcycles, and drag engines. It has done nothing but perform to the highest levels. I know countless people that run RP and not a single one of them has ever had anything but great results.

Will it be the #1 best choice for every application out there? No, of course not. Just as Amsoil, Redline, Mobil 1, Pennzoil Platinum, etc... are not the best choice for every application. Just like those other oils though RP is ONE OF the quality oil choices you have to choose from. It is GREAT oil.

So again I say where is all this proof other than the ridiculous rhetoric that is posted on this one site? Are people relying on the information provided by another oil mfg with questionable ethics issues to deal with? Is that the proof you are talking of? Claims by a competitor that is know to twist and manipulate the truth? Claims that are directly refuted by the test data RP provides on their products?

Let's see here...

1 - RP is a joke because they market their product.
2 - They are bad because they test it against the competition and post the results.
3 - There are all these horrible used oil analysis out there, all over the place, just waiting to show us all just how awful RP is.
4 - The company is unethical for making those results public and trying to show them in a way that favors their product?
5 - RP costs too much.

I see now. Just a couple quick questions? If all that is so bad why is it ok for the other oil companies to do the same things, trashing RP in the process, and have their own bad used oil analysis. Everything I see people bash RP for can be applied to EVERY SINGLE OTHER brand. As to price, I can buy RP for equal to and sometimes even less than PP and M1 sells for at Wal-Mart( qts not 5qt jug ). I definitely pay less for it than many of the other popular brands many here use cost. Yes, some places charge too much but what would they charge for Amsoil or Redline if they sold it? I wager the same or more than they sell RP for. Would that then make those other brands bad? What oil is not overpriced these days?

Now, where are all these so called bad used oil analysis and all these posts about bad experiences with RP? Where are they? They are NOT on this site that is for sure. When you consider the unbelievable bias against RP here this site should be LOADED with all of this so called proof it is so bad. Funny though that 95%+ of the negativity is nothing but complete bull and just opinion with NOTHING to back it up. All these RP bashing posts remind me of a bunch of old ladies gossiping. No proof or documented evidence. Just a bunch of people repeating myths and rumors.

It blows my mind at the stuff people say about this oil and the company that makes it. I have looked and looked and can't come up with all this "documented proof" and used oil analysis on this site showing how bad RP is excluding certain questionable tests done by competitorts that have highly suspect results. All I find are these lame comments that RP is so bad and blah blah blah.

Another member a while back( year or so +/- ) brought all the old RP used oil analysis back up and the overwhleming vast majority were good to excellent just like all the other popular oils. There were a few bad like the guy with the hopped up HEMI but most were fine. Yet we still get posts like this saying how bad things are with RP and that all this documented proof exists. Again I say BULL PUCKEY! Prove it. As Jerry Maquire would say "Show me the proof".

The "truth" is only a very small handful of the RP haters on this site, by their own admission, have ever used it and have ANY experience to back up their negative comments. Some have and have had bad results( not saying otherwise so no need to imply I am saying no one has had a bad result )but you get that with ANY oil. If you got truthful answers from the bashers about who has really used it and who hasn't I bet my last buck 90%+ have never even used it. Sadly, the misinformation and outright bogus posts made by some on here have others believing the negative hype. Mob hysteria and Lemmings running for the sea in all their glory.

The RP bias on this site is actually laughable. RP is labeled "bad" on this site because of a very small handful of bad used oil analysis yet other brands that also have them( they all do )are great and it was just in that application that it was bad. Unbelievable double standard. How do you give any credibility to people that are so hypocitical?

Go ANYWHERE else on the automotive internet forums world and RP has a stellar reputation and gets nothing but rave reviews. Is RP the end all be all of oil? No. Actually there is no such thing. No one oil is hands down better than any other brand. Is RP the horrible, poor performing, over priced, crud so many here on this site make it out to be? Not even close.

Just unbelievable that this kind of stuff persists on here. Open your eyes folks.

So why don't the oil co. and car co. use the Timken test? Duh, they aren't cheap a**es like these Mom and Pop companies.


+1. I don't like oil makers that behave like snake oil salesman. I hope RP won't go and create 100s of weird website claiming to be indi-experts to prove their oil is the greatest the way Amsoil has polluted the internet with their garbage infomercial disguised as facts.

Me too, but you forgot the main thing...

 

[Audi Junkie]

...add the fact RP basicly has no spec beyond API, same as any $2 conventional oil. Nothing is in the public domain which would make a resonable person believe RP offers anything better than PZ, Havoline etc. In fact, I'd just assue use one of them even if RP was the same price. So, you think RP compares favourably to Mobil 1 0w-40, GC and other oils with PORSCHE Approval, VW LL and MB specs? That is known as (reverse) "wishfull thinking".

http://en.wikipedia.org/wiki/Wishful_thinking


"Wishful thinking is the formation of beliefs and making decisions according to what might be pleasing to imagine instead of by appealing to evidence or rationality.

Studies have consistently shown that holding all else equal, subjects will predict positive outcomes to be more likely than negative outcomes. See positive outcome bias.

Reverse wishful thinking, or wishful thinking in reverse, can be said to occur in a person’s mind when, as a stern, relentless and usually pompous follower of a rational notion, he/she expects it to always be valid regardless of, and/or in spite of either not taking into full account all imponderables or, most common and notably, the lack of up-to-the minute research on the subject, thereby resulting in his/her wrongly assuming that decisions, recommendations and, especially, forecasts derived from that notion can only be the result of either factual evidence, or rationality as known to that person at a particular point in time, all of which invariably taking place before all the said imponderables, and up to the minute, yet public evidence are taken into full account."

Wow! Everything I've always wanted to say, but felt that those RP bashers were not worth the 90 minutes it would've taken me to type it...................Well said!!

Some of us RP "haters" have real reason to dislike the oil. It simply has not performed for them. In my case, after years of me bashing RP for it's poor ability at maintaining it's viscosity, a rep from RP actually felt that I should run the oil first, do some used oil analysis, and see for myself how it performed. Well that backfired on them, because after running it in my wife's Honda, it thinned out from 11.3 cst to 8.8 cst in just 2400 miles! And the wear numbers were a lot higher too. In fact, I get much lower engine wear running Castrol GTX in her car than I did with Royal Purple! So how can I like an oil that costs so much, but yet can't even outperform a conventional oil?

If you search the RP used oil analysis on this board, you'll find a ton of them where the oil thinned out considerably in a short period of time and you'll also find the engine wear numbers are higher too. Simply put, this oil is all hype without any performance to back itself up.

Here is a report of the popular Pennzoil Platinum 5w30 in a Mazda3. Looks like it sheared too.................I guess that it makes PP bad now too??

If you google "best motor oil in the world", you'll get plenty of website obviously paid for by Amsoil or its distributors/vendors acting like indi-experts. Below are 3 quick ones. Base on the names of the websites, uninformed car guys would think it is the best stuffs out there and everyone else is a distant second or not even be in the same league. That is misleading and dirty marketing primarily by non-reputable companies.

I don't have problem with Amsoil quality and I don't have any experience with them. It is their marketing tactic that turns my stomach and keep me away from trying one. Their poor availability may also hint at the fact that stores don't want to take a chance with an oil company that is either unknown or not proven. Are Amsoil products go through the same testing as other oil to be certified by API or any other standard institution?

That isn't the best used oil analysis, but it looks like the viscosity is still in range

 

[Bryanccfshr]

D Bone
that Pennzoil Platinum 5w30 sample is within grade and the wear numbers are good for an engine with less than 10k total miles. Got any examples where that oil sheared out of grade ?

 

[ZZman]

NHHEMI: So what kind of miles did you put on those vehicles? What kind of OCI's were you using?

 

[buster]

It's all marketing. Oils are more similar, than different IMO. Most use similar additives and base oils from a handful of companies. It becomes a marketing game. Some oils meet more specifications than others, and there are proprietary formulations, but those that do meet the same spec's usually perform similarly.

What I've noticed most is that each company has a few really good oils, and some that are just average/below avg.

I guess that's really what I was looking for when I first asked another poster why it would be one of "the last" oils he would use. I've seen some references to viscosity decrease, but that's about it.

I've used Rotella T synthetic and M1 for years, Castrol GTX and Valvoline some, so I'm not an RP devotee or apologist. I've bought exactly 4 quarts of RP in my life, and that was for a manual transmission (in which it actually seems to have alleviated a synchro issue that I was having with Redline MT90, believe it or not... although the jury is still out until it gets more miles on it.)

I'm just looking for facts here. I was somewhat attracted to RP because it is a PAO base, is SL rated and therefore possibly an advantage in my old flat-tappet 440s with big spring pressures. And its a Texas company and I'm an unabashed "homer".

Not that I've got any gripes with Rotella Synthetic group III, just another data point I've been looking at and trying to gather facts on.

Maybe the RP, with its higher detergency, just cleaned a bunch of deposits hanging out in the engine. There are too many lurking variables to be able to draw a conclusion on A SINGLE UOA.

It sickens me when people try out a new oil, and then freak out after one less than positive analysis. Correlation does not equal causation. And you need to study trends to see the broad scope of things.

People do the same thing when a stock drifts downward. Buying high and selling low doesn't make you any money. The long haul will give you a better idea.

The dealers can't say things on their independent sites that are not true. If there is something untrue then they should be pointed out to Amsoil. All oil companies make marketing claims, Amsoil is no different. "Dirty marketing" is a strong accusation....show me something illegal and I will report it.

Amsoil is available at many stores. So I'm not sure where you are coming from. Your thinking is a little off on that one. Amsoil chooses NOT to sell to the Walmarts and Kmarts....sticking with small chains like Napa and Car Quest, etc...and of course your local dealer. Amsoil is headed for 40 years in business. It's not some dirty little company, it's fairly large actually. Amsoil had the first API certified synthetic oil back in 1972, but now only has it's lower grade XL and blend line API certified, by their own choice.

 

[Ibrahim]

I know it is totally off the topic...but do we have the "Film Strength" published for popular oils?

GC
Amsoil
Red Line
Motul
PP
Mobil 1

I sure would like to know, I tried but couldn't find Film Strengths being published in the TDS!

 

[sprintman]

Same with Redline, they get one UOA, panic, and move on.
