Royal Purple Oil Experience - 2005 Mustang GT

[2K05GT]

I don't want to start an OIL's War.. But I want to express my Recent Experience with Royal Purple 5w20 in my 2005 Mustang GT. I ran Royal Purple since I bought the car and it had it's first Oil Change (July 2005) 70,000 miles lator and I replaced the Stock Cams with COMP 127200 NSR Cams. Anyway, I did not look at the cams until months lator when I noticed they looked new, confused I asked a friend to loan me his cams from his 2007 Mustang GT with 40,000 miles using Mobil 1 5w20.

Right off the bat I noticed the scaring and coloration. So I decided to Document the findings. Could the Royal Purple Marketing be True?
This Image shows Both Cams with Descriptions.




These Images show No wear from the edge of the Lobe to the center of the lobe on Royal Purple 5w20
Measure the Edge because I need a surface that has not been touched by the follower (Baseline)



Measure the Center and shows no wear



The Following Images show wearing on the Cam Lobe from the follower on the Mobil 1 5w20 Oil sure 100th of a mm is minor but the Royal Purple Cam has almost twice the Milage...
Again Measure the Edge for a baseline



Then the Center and there was some wear.



So I had to make sure my test vehicle was not a fluke so i borrowed another set of cams
from a 2006 Mustang GT with 36,000 miles all with Mobil 1. Oil


with 36,000 miles who always used Mobil 1 as well. Again the Cams look simular, (Top cam from 2006, Middle Cam from 2007 and the Bottom Cam from the 2005)

You can make your own conclusions but from this test I would have to say that Royal Purple's Claims about Less friction, less wear is not a gimick...

Amsoil and Royal Purple are very simular in that they are 100% Synthetic (No Mineral Oil Base Stock) like Mobil 1 and they both add ZDDP and additive that cleanes the engine and reduces wear. Royal Purple adds a small amount of a Moly simular to graphite this may be what created the reduced friction.

Here is the Oil Analysis from Blackstone
I did use some race fuel to do some tune changes and dataloging, I was changing the timing and did not want to hurt the engine
by adding to much timing. I am sure the knock sensors would have pulled timing but better safe than sorry.

I wouldn't ever use anything but Royal Purple. Been using it for a while now. And I'm never using anything else.

Ok with weather this weekend being nice, I was able to help my friend remove the Valve covers from his 2005 Mustang GT with 61,400 miles, he also used RP the entire time. His car is a Manual and drives the snot out of it, he has already killed one clutch. He is removing the covers to have them powder coated.

Here are pictures of his cams. (I did wipe them down for the pictures)
