who's running royal purple? i know weve had a ton of oil threads but just wondering who is running royal purple only please thanks guys! anyone have sampling results from it?

 

I have used RP synthetic fluids for 12 years in everything from my Scarab to my John Deere tractors with no problems or failures. I use their regular engine oil, racing engine oil, gear oil, tranny fluid, coolant additive, grease, 2-cycle marine engine oil, power steering fluid, etc.. And, OBTW, I am not a RP dealer. The only vehicle I have a non RP fluid is my X tranny. For right now I have bought into the Ford propoganda of using SP only but I'm waiting for some data from RP and will probably at 60,000 miles go to RP HD synthetic tranny fluid in my X. Right now I run 20W-50 in the X, RACING 21 in the Corvette, 15W-40 in the T-Bird SC, RACING 51 in the Scarab, RACING 21 in the Yamaha Grizzly, 20W-50 in the various farm tractors (JD, Farmall and Kubota), marine 2-cycle in my Yamaha jet ski and 50 HP outboard. All vehicles use RP gear oil except the tractors.

Sorry for being long winded but I have had great success with RP. I strongly believe that RP engine oil is the reason I have not had any turbo or injector issues with my X that now has 50,000 miles on it. It could blow up tomorrow, but right now I'm a happy RP camper.

One more thing about RP. If you contact them via their website, they will respond quickly with an answer and depending on the question will validate the answer with data.

I have had mixed results with RP & have chosen to return to Delo syn in all my fleet vehicles the biggest problem was cost & availibilty I was rarely able to get sufficent Quantity & cost was 15 to 20% higher.

 

We used RP in Nautronics azimuthing drives at my past employer. My current employer runs it in a 20 cylinder MTU booster pump engine. While we have experienced the noted supply issues and greater costs, lube oil analysis has never revealed any oil influenced issues in either application.

 

welcome aboard NH AR9mm, good to see someone with "little" frac pump experience

 

I use it and probably always will.

My 2nd choice is amsoil.

 

I first used RP in my RX8 rotary and was amazed at the improved performance and better gas milage especially in the very cold winters we here in the North East.
I just got a 2004 E450 Diesel RV and put RP in that - works fine but I have no experience with other oils in this Diesel- I get 11.3 MPG and that seems pretty good to me for a 15,000 pound RV

 

Recently, one of the diesel magazines stated that one could go 12k miles between oil changes when using RP oil. Is this true and has anyone tested the oil at 12k to verify?

 

sure can, in fact u can witgh any oil but only if the oil is sent off for a OA and they say you can keep running it...as for just running it for 10k off the bat is dangerous and a market ploy...

 

If UOA show that you can extend the drain interval, than it is fine with any oil as long as the UOA proves it out. Problem with the 6.0 and the HEUI is that using the engine oil as a high pressure hydraulic fluid to fire the injectors, shears the oil down very fast and so far extended oil changes have not been possible with any manufactures oil used in the 6.0. Go to the BITOG website and read the threads on the 6.0 and extended oil changes, there are many UOA results posted there.
Dirty and improperly performing oil in the 6.0 will lead to injector failure in short order.

Hope this helps

 

ABSOLUTLY!!!!!!!!!!
