I was reading the diesel power or diesel world mags earlier and I saw they were using royal purple in there test dodge. They changed all of the fluids trans, gear, and engine oil. I was wondering if anyone on this forum uses it and how do yall like it.

I would not use it if it was given to me.

I've seen test results showing it turns to crystals if used for extended intervals......like sand.

Have you ever noticed most of the big advertizers don't have very good products?

Go ask around at the racetrack pits. Find out which manufactures give thier oil away. Which ones charge for all of their products?

Those who don't edited by admin the product are the guys who have nothing to prove and usually have the good stuff.

Do you think Trucks or Horsepower TV pay for that stuff?

Thanks for the info. The reason I ask is because alot of my friends use it in there cars and they seem to like it. I have never seen any results on it so I thought I would learn more about it.

i am running it in my truck and i have no problems with it, no crystals or sand like side effects, if it is good enough for Greg Hauges 890 horse power diesel its good enough for my truck.

That is the most rediculas thing i have seen on here. I am not sure what test results you have seen but I use RP in a multitude of aplications and in sever conditions. My company purchases over 5000 gallons of 15-40 a month to run the Cats on our vessels these are 1800 to 2500 hp engines. We also use over 20000 gallons of there syndraulic hydraulic fluid a year bearing grease and gear lube. These engines clock an average of 7200 hours a year and since our change to RP our rebuild intervals have been cut almost in half.

I have run RP in my last three trucks and have been nothing but pleased with its results. I have seen results of tests done on a engine that ran 5600 hrs with no oil change they only topped it off when needed and the engine showed minimal wear and no signs of sludge build up (or crystals).

I have to call bull on this untill you can fork up this so called test results. I believe you have been mislead.

CrazyCooter

That's OK. Use it if you like.

It's been years since I saw the data. I wouldn't know where to look now, nor do I care to.

I wouldn't put it in a lawn mower.

RunninLean

so your happy with bashing a product with no experience or proof of there being any thing wrong with it? Kudos to you then.....

CrazyCooter

I would not say "no experience". Just not the kind you want to hear about.

Just reporting what I saw.

Like I said.....use it if you like.

Thanks, I have nothing but a quieter engine after switching from conventional oil to Royal purple. I personally think all synthetics are way ahead of dino oil. It is up to the individual of what he / she likes to run. I choose Royal purple due to countless reports such as yours in where engine rebuilds and generator rebuilds are less than other synthetics used in past.


I know of a power plant
"Nuclear power plant near by that will only use royal purple b/c they are the only company that could meet there specs.. Not trying to start an argument, I just thought that was kinda cool..... If a nuclear power plant can rely on it , I think we are safe for our small cummins to rely on it...... thanks jason

I wouldn't use anything but RP gearlube! I used their 15w40 for several years - ext changes/bypass/UOA and it was better than most. The TBN held up terrific! Craig

Just swapped Tuesday night from delo 400 to rp both 15/40. Havent driven the truck much but it did seem to start and shut off easier and MAYBE idle a little quieter.

I pulled a sample of my delo to be sent to Cat and I will pull one on my RP when the time comes and compare.

I haven't switched to the RP engine oil yet, but we use the RP hydraulic oil in pumping units that run 24/7 non-stop and it has reduced oil change interavels, temperature, (we no longer need oil coolers) among other things. It's really a great product, not cheap but a great product. I tried it out in my wifes SUV and sent the oil off to get checked after 15k miles. They had said it looked fine and could probably extend another 3-5k next time.

I just haven't put it in the dodge yet cause the Tech at the Dodge house told me to wait till at least 20k miles before switching..

I love the stuff. I wouldn't use anything else. My mpg improved, the engine seems to run smoother and my butt dyno says it has a little more power.

i used RP in a F350 Powerstroke for a couple of years with no problems to speak of. it is expensive but I think you get really good results from it. I will be switching to RP on my next oil change and will not think twice about it.

I work here in Houston, Tx along the ship channel. There are so many refinery and chemical plants that you cant even count them. As some of you know most have HUGE motors or compressor that run non-stop. I have noticed that most of them are using RP as the lubricant in these motors and compressors. That tells me one thing, its some good stuff. These plants cannot afford to be down for a second because of equipment failure. They depend of good products to ad them in making a wide range of products we use everyday. When I see them using RP on machinery that is almost bigger than some houses I have no fear in putting that into my little engine I drive on the street.

That is just my experiences!

What weight are you all using? Switching to RP next time.
