Watched this video on Boattest.com, they are doing a test of Royal Purple oil and filters vs. "regular" oil and filters on boat engines.

I am not able to tell how scientific this is - looks like Boattest is talking regularly about RP and mention's no other brands, so it is probably an advertising deal - but the results look quite impressive nevertheless.

What do you make of it?

RP pays tons for fake non factual endorsements like that. That is really not a test any more than pouring 2% milk on your breakfast cereal and then endorsing it. Soon they will have Michael Phelps or Tiger Woods endorsing it.

Maybe Brett Farve pouring RP into his SUV or Arnold Palmer pouring it in his 100 year old tractor....yeah sure...

Several weeks ago we broadcast a video we made of our test on Long Island Sound comparing Royal Purple synthetic oil with standard motor oil. It was one of the highest rated videos that week for viewership and our testing methodology also generated numerous comments from cynics. The irony is that several months ago when Royal Purple first asked us to test their oil, we, too, were a doubting Thomas. So we understand the sentiment. But the test speaks for itself: the twin 5.0L engines when being lubricated with Royal Purple actually averaged a 10.7% improvement in fuel economy over the rpm range measured.

Now really people...if RP really increased MPG 10.7% wouldn't it be required by the government for CAFE? Wouldn't GM, Ford, Chrysler, Honda Toyota & Nissan all use it as FF versus spending millions to get a 5% reduction????
 
A few weeks ago BoatTEST.com conducted a comparison test on two Volvo marine engines run with conventional mineral-based engine oil and Royal Purple Synthetic Oil. We found that the boat we tested in Long Island Sound had at WOT speed of 4.3% more with Royal Purple and got 6% better fuel economy. At best cruise fuel economy with Royal Purple was 9.6% better. Actual in-water apples-to-apples testing is challenging and we wanted something more. “More” in this case meant testing in “Lab Conditions” and that means on a dyno. We passed that request on to Royal Purple and they commissioned the folks at Horsepower TV to do just that.

+1 It just takes a little common sense.
 
As I was reading this thread, I was thinking this sounded familiar.

Hasn't "Boat Test" been shilling for RP for a while? Memory tells me this has come up before.
 
I looked and found something Lars11 posted last summer about 'testing' RP ... and bumped it.

Then I went to that link to find the video on filters. Didn't find that but instead I found the "comments" tab and clicked on it. Seems a lot of pretty irritated Boat Test fans thinking the site really sold their credibility shilling for RP!

Basic common sense says they should have tested numerous brands of oil in a "shoot-out" format ... but this isn't about picking the best oil. This is about rewarding RP for advertising dollars (obviously).
 
Sorry sr17, Some people here (myself included) don't care for Royal Purple. But I do occasionally recommend at least one of their products (Syncromax) for certain applications and I've never heard anyone say anything negative about BoatTest.com outside of this conversation.

The problem is that BoatTest.com didn't even try to be fair with that "test". This was a paid for infomercial, straight-up. Refer to the criticism on their own site. It's not just BITOGians.

1 - Please provide proof in written format( copy posted here as a JPEG, PDF, GIF, etc...is ok as long as it clearly shows what it is so we know you didn't make it up as you alwys do or a link to the proof )that RP paid that web site to do that test as you claim OR that they pay for fake and non factual endorsements as you claim? Please back that up with actual proof. I think RP would find your continued false and possible liablous comments interesting. For someone who hates the company and has never used the product you sure have a lot of opinions on it in every thread that comes up on it. All that site says is RP "asked them to test their oil". Asked does not = paid.

2 - Why would you in ANY WAY apply any negative comments to RP based on what a web site does with it's testing of products? If Boattest.com slammed RP you would be all over it and saying how it proves RP is junk. Because it is a positive test it must be bought and paid for by the company. What a joke you are. IF you are going to hold RP to a standard like that then start doing it to every other brand out there please. I can think of a company to start with without any trouble. Right Pablo.

And??? There is also banners and advertising on their home page for Sea Ray boats, Formula boats, Worldcat boats, Yamaha, and others. So your point is what? That anything positive they say about those mfg's is also questionable or is it just the RP?
 
I see many people here commenting on the comments left. Well did anyone bother to read those left by the guy who obviously works for the site?

Too many variables for a real conslusion. If the RPMs are the same the speed will be the same unless trim, weight or wind are different. What viscosity oil was the baseline? What viscosity was the Royal Purple? Did Royal Purple supply the boat and driver? You lost a lot of credability on this one.

In Answer to J,Paskvan – We picked the boat, went to a Pep Boys and purchased the oil, and it was BoatTEST driving. No RP staff or representatives were on site or involved. All oil was 10W 30

So the site paid for everything and did the testing, at RP's request apparantly, but it was not paid for nor done by RP. HMMM, isn't there another company that does similar things and their results are always labeled as the gospel? Something about an industry leader for decades???

NOTE - for the record. I have not been compensated in anyw ay for these comments nor am I affiliated with Royal Purple. While I am a BIG RP fan, and have even run it in outboards, I do not think it( ie; RP oils, gear oil, etc... )is the best option for a marine environment. I am actually running Amsoil 4-stroke oil right now in my boat.
