Royal Purple oil
So i guess we wont get to see the actual test results. Just some bar graphs that some intern made with excel. Let me rephrase or restate what we have all been asking. Do you have any tests that show real world results. ASTM testing in a lab on oil that has never seen the inside of an engine dosent tell me much. Amsoil claims to provide more horsepower also. Where is the proof of this one? Can you give me the link to that astm test?
As far as wikipedia goes. It is a much more reliable site to find information than looking through marketing pages of a manufacturer. Anyone can post anything. However if you dont know how wikipedia works you shouldnt knock it down!
As far as im concerned this thread was dead when you came in here and started attacking or contradicting everyone that said anything about an oil other than amsoil.

Wikipedia is not an accurate source since it's A. an encyclopedia and B. user modifiable. The issue here is not Amsoil, it's Royal Purple. Tests have shown that Royal Purple shears down to a lower weight after a relatively short amount of time. This is not a good thing for an oil to do.

Anyway. Regarding Royal purple. Back when i had my truck a lot of fellow truck owners were using the RP gear lube in the diff's. Does anyone know if the gear lube suffers the same problems as the oil?
Here is an Independent test of gear lubes.... Again, done through "Accredited" Labs.

Love those results on RP and Redlne... Page 19 for end results

Thank you Oil Doc. This is a much better example of Amsoil quality compared to others. The report was presented as a scientific paper would be (I'm a biologist myself) and all the testing methods, focus of the test etc was clearly explained and to the point. No "this is better than that is" opinions. Just straight up results. Very nice indeed.
That is exactly what is is.... If you are a Biologist, you are familiar with the term "White Paper".
Those tests were performed by several of the Top Independent Testing Facilities in the US
Have one that shows how bad RP 10W-40 Shears as well....

I tried Royal Purple in my Eclipse GS-T after some STI guy raved 7 days to Sunday about it, and didn't feel any difference at all. My girlfriend put Castrol Syntec in her GTS and it literally felt peppier driving out of the bay. She's been using that ever since she first tried it, and literally immediately after the oil change, the car feels different. I'm going to be using it in my car when my next oil change comes around.

Don't get me wrong, I am not a proponent of RP by any means as the oil shears out of grade quickly which will usually create more HP but in turn have less protection.
The Castrol SynTec on the other hand is merely a Hydro-Cracked oil and doesn't even use a great base oil to start.

I find that quite odd if.... IF... The viscosities of the oils were the same and, IF The Royal Purple was not past it's useable life... At that point, any oil change will feel better.. Of course, RP's useable life is about 1/3 the life of what it should be as it fails to make it past the 1st Sequence of a Critical 3 Sequence test.

I just changed my oil yesterday with royal purple and the car seems to be more slugish than before and os not reaching boost as quick as before, I will NEVER do another royal purple oil change again. I've been using mobil 1 full synthetic and it has never failed me. Definitely not worth the money.
mobil 1 ($22) > royal purple ($33)
mobil 1 ($22) > royal purple ($33)
