I'm goin to change my oil either tonight or tomorrow. I've ran RP since new, so we will see. It's a honda, so if the UOA is good people will say it's because it's a honda.

just wondering if people actually have stories about how royal purple caused damage to there engine diffs or tranny caused by royal purple. personally i like and heard all good about royal purple from people who use it. and personally would use it over amsoil because of the nuts who use amsoil. kinda like the nuts who worship obama like a god its repulsive.
just wodering if people have experienced first hand royal purple actually causing some kind of mechanical failure. i had a 65 pontiac tempest with a 326. the oil made a tremendous difference with engine noise and knocking and performance.
the onlt negative i have 2 say is its over priced .
thanks
There have been a few instances where RP did not perform well in a specific application. There is a guy on here with an extreme Hi-Perf HEMI engine that had bad luck with it as one example( think it was the race formula though not the regular street stuff? ). I believe there is a guy with a Buick GN turbo engine that has not had good luck with it either. However, they are the exception and not the norm.
No one has had any failures directly related to using RP on this site to my knowledge( or any other oil that I know of - if so it is rare ). It has also performed very well in the UOA's despite claims to the contrary. The overwhelming vast majority of those bashing RP fluids here have never even tried it. There are a few who tried it once on short OCI's and then ran UOA's and got poor results but that is to be expected. I wonder what they were thinking would happen? For those who have used it long term it has done very well.
I don't get this "shady marketing" or "no info given on the product" stuff either? They are one of the most straight forward and honest companies out there when questions are asked. They will even be completly honest and tell you if you should not use their product for whatever reason( ie; not compatible, not warranty acceptable, etc... ). They do very little marketing where they talk about the competition unlike other companies that make a living off tearing down the competition to try and pump their product up. That is NOT how RP does things. Recently RP made a simple comment about wear vs the new castrol Edge. Now they are shady marketers??? WTH is that about? They are actually a very honest and stand up company. They are not going to give you their secret formula but they will answer questions with a good faith effort.
I have run RP in a ton of vehicles( oil, tranny, diff's, t-case, coolant additive )and have had nothing but excellent results. For some reason on THIS site it is hated. Only place I have ever come across it. Every other place it is one of the top 2-3 talked about.
As to cost. Yes, it is over priced at many parts chains like PepBoys and Advanced Auto. What oil isn't overpriced these days though? $4 for conventional oil? PUHLEASE! As much as I like it there is no way in heck I pay $9 p/individual qt the way PepBoys charges. NO WAY! However, you can get it for a very competitive pricing if you shop around usually. I pay just $5.75-$6.25 p/qt for it depending on where my speed shop guy gets it. Penzoil Platinum sells for $5.97 p/ individual qt at Wal-Mart around here and it is $6.50-$7 at the parts stores. So, I can get it for less than those other oils in single qt bottles.
RP is a great company that makes great fluids. They are just one of many to choose from. Not the best( there is no such thing )and certainly not the worst as so many make it out to be. They are my 1st chocie whenever possible and I have never had a bad experience with their products despite a variety of uses/applications.
IMO the one big negative facing that company is their inflexibility and refusal to deal with changing API standards. They either need to reformulate the current oil or offer a second line to supplement their best line( similar to Amsoil's XL line )that can meet the most current API Service Level requirements and new vehicle warranties. Sticking with API SL, with API SN coming out anytime, just because they feel it is better is going to result in a ton of lost sales. Adapt or die. I hope they adapt because it would be a real shame to see them fade away.

I would look through the used oil analysis section and unless I am wrong isn't Royal Purple a Group III oil.
My searches say it is definitely a Grp. IV with some Grp. V esters

I do not consider myself a RP "basher" by any stretch....
But my engine had lousy UOA's (multiple) and reflected shearing to a 20 weight (Racing 40 RP). So I don't use it nor recommend it. Simply put...I have much better results with much less expensive oils.
Some folks can have wonderful results with RP. I didn't. Doesn't make it a bad/or good oil. Just not good for me.

^^That`s what I`ve read as well. It`s a grp VI/grp V (Synerlec being an ester based additive). Can`t remember if I read that here awhile back or somewhere else. Imo where RP really shines is during wot runs. Talk about some smooooooth upper level rpms!!! To me it seems like an excellent oil if you like to pound the heck out of your engine.
If I can remember to do it,I`ll do a uoa on my next run with their 20W50 street oil.

I love the fact that the oil's "performance" is being judged based on information provided by a testing method (UOA) that is meant to gauge contamination levels and lubricant longevity and not engine wear.......
Last edited by a moderator:
according to royal purple your first 2-3 oci are supposed 2 be 3k-4k miles because the oil is cleaning and flushing the engine. then after that your ocis can be 12k miles. your uoa would be poor the first ane or 2 then should get better anyone actually do this and what were ur results

Wonder if there are any material data sheets on their oils? I looked on their site,but couldn`t find any.

Funny how at a bunch of other car sites, I see the banners: RP Increase Horsepower, blah blah. At Bob's, an oil site, I see none.

I would look through the used oil analysis section and unless I am wrong isn't Royal Purple a Group III oil.
A fellow posted a spreadsheet with over a hundred UOA's on Subaru s.
I eliminated the data with less than 20,000 miles (break-in) and OCI less than 4000 miles to get rid of short OCI's. I was left with 90 samples.
I then sorted the data by ppm iron per 1000 miles.
Amsoil, Redline and Royal Purple dominate the top performers.
I get very similar results for chrome per 1000 miles. Lead, copper and aluminum are more of a mixed bag.

I have friend who swears by RP ATF MAX, I tried finding more about whether or not it will be beneficial for me to switch from Amsoil ATF...but what makes me stick with Amsoil over RP and Red Line ATF D4...is that neither of these brands tell you exactly for how long is their product good for under normal service....but Amsoil does (25k miles or a year)!
I actually read somewhere on a Amsoil related website that RP is loaded with MOLY which makes it a bad for engines when used for an "extended OCI"...and most people are only willing to buy and use expensive oil mostly not just because syn oil give better protection but also for longer period of time...!!
at least that's what I was able to summarize from people who oppose RP!
On BITOG forums a lot many people found it to be bad oil than good...I believe you can find virgin and used Oil analysis on this forum...I for one have no opinion...

The observation Audi Junkie made is a good one and begs the question, "Why doesn't RP have their banner on BITOG?"
