:iagree:

It's only junk because it's overpriced and even a lesser oil than several cheaper off-the-shelf oils.

Any oil marketed to increase horsepower output is falls under the category of snake oil BS. I have nothing more to say on that :rolleyes:

Royal Purple is junk, not because the oil sucks, but because the marketing and pricing does. Kind of like AMSOIL... :roflpuke2:

How many engines have you built and torn down after trialing various oils?

Ever built and torn down an engine after using Royal Purple?

Didn't think so. I have, among many other people who actually know what they're talking about.

Yet no facts or proof of these statements just opinion with hot air behind it! I am engineer please show facts. Tests and data mean something

It's not worth my time to post up evidence of bearing wear over a few years of tearing down and building engines. Too much to present, and I doubt anybody except one who possesses actual tuning and engine-building skills would be able to reasonably interpret such evidence.

Here is a one-line summary of what I found: all oils marketed as synthetic protect equally well, essentially. However, I have found some oils such as Mobil 1 0W-40 and Red Line 10W-40 to provide enough protection to actually prevent and mitigate engine failures.

Anecdotal engine building wear analysis means everything to people who actually build engines. Probably doesn't mean much to somebody who pays a shop to install bolt-ons :ugh2:

To answer your question: five small block 302, I tore my dirt bikes down every month for twelve year two stroke and four. Did two GSXR 600's, Ninja ZX10, and one alpina B7S which I doubt you know what that is.

How many have you tore down and built? How many heads have your decked? how many have you ported and polished?

Talk is cheap so lets see this so called data. Doubt you got it and doubt you have a mech. engineering & physics degree to really understand what you would be looking at.

:bowrofl:

OK chump. Let's recap how you started this argument:

Doesn't seem like something who has a would even utter. Seems like something a fanboy would rattle off. Why don't you present some hard evidence showing Royal Purple is better than everything else? As an engineer (whooptefucking do), you should know that the burden of proof lies on your end if you're claiming a single product is better than all else.

My only statement was that RP is overpriced, mis-marketed garbage. And it is. The oil is good, but definitely no better than any other Group IV or V-based synthetic.

I'll let my actual tuning, mechanical, and engine-building experience speak for itself. Seems a lot more relevant than having a piece of paper that supposedly states you have a conceptual understanding of such things. Experience > Degree.

Somebody is answering questions with questions and is running from his previous statements and I think it is you! What the matter, you been called out and you are running now, no facts or answers just **** measuring questions. Let me put my waiters on the **** you are talking is starting to fill this thread up!

Hey I think your wife called and she wants her car back!

Yeah... stop projecting :rolleyes: You're making yourself look like an idiot.

Up until your inane post, this thread was actually filled with useful information. Claims, specs, and personal proof that certain oils do indeed protect well, no claims bashing other oils. It's your fanboy antics that opened the can of worms.

Burden of proof. I'll say no more.

WTF? :ugh2: That doesn't even make any sense.

You, sir, are a moron. And I will stoop to such a level of immature name-calling just because of this idiotic comment. :tiphat:

yet u keep on going....... What facts! I asked and got an opinion. Facts have supporting data! You must not understand what i mean by data!

So you stop projecting!

OMG you really are a dense idiot.

You are the one who started the claim that RP is BETTER THAN EVERYTHING.

Burden of proof. Prove it, or shut up.

All I have to say is it's overpriced and mis-marketed, much like AMSOIL.

Gosh Guys, I'm sorry I asked this question. I didn't want to start something negative. I have decided to go with the larger Purolator Pure One Filter # PL14610. I used nothing but Purolator Pure One's until GI Joes closed then I had a hard time finding them. I'm going to buy them from Amazon, they have a great track record with me.

As far as the oil goes, the 0W-30 synthetic from Castrol seems to have the best results. I just want to confirm it would be okay for the NW area here in Tacoma/Seattle. According to the results from another thread Red Line did horrible and Royal Purple was just okay.

Man your mean! :icon23:

Certain weights of Red Line are no good, this is true. I personally would never use Red Line 0W-30 or 5W-30. In 10W-40 form, and used for racing, it's good stuff. :tup:

You should be fine with both those. That is a good oil filter. I am bored and love to see how many people get pissed over stupid stuff like oil.
