If it is purple when you install it what color is it when you change it?

pink?

Seriously, how purple is RP when it's fresh?
It'd make a good oil to bring to the dealer without the dealer tech trying to steal your $$ oil by pumping in dino from a drum, and keeping the good stuff for them selfs. I had a tech stealing my M1 when I bring my car to an Audi dealer.
 
unless engine is real dirty will still have a brown/purple look untill you get some miles on the oil.
If they steal your oil do it yourself or have a neighbor kid do it and watch him.

Royal Purple looks like grape Cool-Aid or Grape Juice. Fun to put Barney in the motor to kill him dead. (Sorry just hat that synthetic dinosaur). Looked like any other motor oil I have drained in any car I have seen it.
 
RP looks like a very dark purple with a brownish tint. After 1k mi or so, it gets very black. By 5k mi, it's totally black. Which, BTW, as has been pointed out by others, is just what any other syn or conventional oil looks like after it's been used awhile.

It's purple to represent royalty, hence the royal price you have to pay for it.




So what does that say for Mobil, castrol, etc. when they are more expensive than royal purple?
 
Actually, they aren't quite there with the Royal Purple.. A buck or two or three under, depending on how you buy them. Purple is ALWAYS 8.00+ here..

8.00 for GroupIII? They're insane. Might be time to break out the trick like the blue bulbs that imitate HID. Where's my purple oil dye?

I can get it for $6.95 and it's not a Group III. It is PAO for the API approved stuff and a Group IV & V mix for their racing oils. But as stated above, the color only last for about 500 to 1,000 miles.
 
Its amazing that no one complains about the price of RP and we all know its GPIII. But Mobil 1 changes to GP III, its cheaper and people are having a fit.
 
I bought 3 quarts of there 75W140 gear oil just this past weekend.It was only $8.50 a quart at my local speed shop.I'm having my differential rebuilt in a few weeks and wanted to see if changing the fluid would quiet it down some;it did,but not much.
 
Royal Purple API Certified 5w-20 seems to just fine in my 2005 Honda Si. I've had good used oil analysis with it and it's made in Texas.

Eeeasy, Jason. I repeated the same thing, and Johnny, who knows a thing or two about such things, made mention that it's PAO. Scroll up.

Johnny, did they test the stuff to GF4 standards, or did they just go for the API certs?
 
Since this whole Mobil 1 Group III discussion came up I thought I would contact Royal Purple, so I did. I sent an email to David Canitz the Tech Service Manager for Royal Purple and asked him point blank, does any of your products contain Group III base stocks. Below is David's reply.

"Both the RP 5W20 and XPR 5W20 are synthetic products made with Group IV and Group V synthetics.

The XPR has more select base stocks and a more robust anti-wear package and would give higher performance but it is not an API Licensed product like our PCMO.

We currently do not use any Group III hydrocracked products in our production. There will be a small amount of diluent oils in either formulation consisting of what ever base stock the additive packages are dissolved in from the additive manufacture - these could be Group I or Group II base stocks."

Now I've known of David for quite some time and he is well respected in the oil industry. He has a chemical engineering degree from Marquette University and has been with Royal Purple for many years. If he tells me there is no Group III in their products I believe him.

He told me the PCMO line of product meets API SM/GF4 standards and is licensed by the API. I know right now most of the labels you will run across say SL on them, but I have seen some of the 5W20 and 5W30 with the SM labels. I'm sure as inventory turns more new labels will show up.

Mine never turned black in 6500 miles, just a dark brown, just like all the other oil that has come out.

I may give it a try again in a few years when my stash is gone.
