So you think royal purple is THE oil!

think again!
Truth in Advertising: BP v. Royal Purple

By George Gill

Royal Purple Ltd. was black and blue after BP Lubricants USA took it to task over advertising claims for its synthetic motor oil, finding a receptive audience in the advertising industry’s self-regulatory forum.

I believe word of mouth from others experiences over anything a company will tell me as the company isn`t about to bash there own product, nor is the middle man who`s trying to sell the product. Just like myself, many times I`m quick to call Accel products junk after having countless bad experiences with there stuff. I don`t have any experience of Royal Purples motor oil or tranny fluid, but there diff fluid is all I use and it`s great stuff. After 7 years of use my limited slip diff still doesn`t pop or chatter. When I used the regular diff fluid with the GM additive I usually got about 3 years before the chatter returned.

Royal Purple

I have used Royal Purple for the past 7 years in my 2004 GMC Envoy and 2003 Dodge Ram 2500. I have it in the engine, transmission and rear end and run 5-7 thousand miles between oil changes. My fuel milage in both vehicles went up from 2 - 3 miles per gallon in both vehicles. That is a conservitive number. I also put an over size tranny pan and rear end cover on both vehicles to help with cooling in the desert heat. I love this oil. I also tried Lucas but it did not give me the same fuel milage gain.

Royal Purple

I have run Royal Purple in my Envoy and Dodge Ram 2500 for 7 years with great results. I go 5-7 k between oil changes and have got from 3-5 miles per gallon increase. I also run it in the tranny and rear end along with over sized pans to help with the desert heat. I tried Lucas and Mobile One but did not get the same fuel milage. I love Royal Purple.

I'm sorry, but I have to doubt claims of getting 3-5 mpg better with a certain oil. That is a lot of horsepower going to friction losses.

I did a dyno test a while back with a 78 Camaro I had with a zz4, HOT cam, air gap and Ede 750. Ran 10W-30 Valvoline VR1 on the dyno, 3 runs to establish an average. Changed to RP 10W-30 XPR, drove the car about 60 miles and made 3 more dyno runs. Gained an average of 13 HP and as much TQ.

If an independent study is done with about 4 or 5 different oil brands I would probably believe them. A test done by ANY company testing their product against another is telegraphing the results. PLUS, the oil they pick on is the one they're afraid of.

LMAO 327, ok now the article specified RP synthetic oil and from the sounds of it this is in regards to its use on the average everyday vehicle, sound about right? to me common sense says an oil that cost $8 and up is not meant for your standard Honda or Chevy envoy rolling down the highway that's why the manufacturer recommends a certain type of oil. now for those of us who do some racing and are making upwards of 600+HP it seems to make more sense. i have been running royal purple in my car for years now and have yet to have an issue but then again i never had an issue before with pennzoil product before either. so lets expand this a little bit has anyone every had a major mechanical failure after switching to a royal purple product in their street car or race car? what was it? whats the pros and cons? is it worth it ?

Merged this thread, same subject, almost a duplicate post, are you pushing this stuff?

I doubt you can find anyone that had a major mechanical failure with any type or brand of engine oil, just not going to happen.
