AZ has a good deal on royal purple with a k&n filter. Just wondering how long it will last in my f150. I have heard people go 10-20K on it, whats your opinion?
How long will Royal Purple last?

Depends on driving habits.
It should last at least 10K, if you would like to go further than that, I would suggest a UOA around 9K and wait for the data. Otherwise....10K should not be an issue. What does RP say?

I didn't think AZ sold RP?
In my applications I use it just like I use all synthetics, about 10K.

I'd say at least 8k.....but perhaps go 8k get a UOA, then go from there...

Ironically, they don't "recommend" an interval, much like the other oil manufacturers do....
But come on, it's synthetic, it's gotta be at least comprable....hehe.
Obviously, if your towing, off-roading, etc....that could change the interval as well.....

Several years ago Royal Purple UOAw were showing a loss of viscosity, but I believe they fixed that problem.
Royal Purple says it will last for 12,000 miles or 1 year whatever comes first but they also have a disclaimer of following what OCI your car manual calls for.
Run 5K, pull a sample for analysis, and go from there.
Thanks for the replies all, would it be worth it to pay a little extra for RP?
Pepboys has 5 qt RP and a RP filter for $40
AAP has the same deal for $43 i believe. Not too expensive really when you consider buying like a jug of M1 EP and a M1 Filter or something similar.

Sure, if you plan to run it for an extended period and/or run the car very hard. Otherwise you won't be taking advantage of its benefits over a more benign oil.
