Why Use Royal Purple?
Royal Purple formulates its products to maximize performance in real world applications. Numerous independent parties report performance gains by using Royal Purple lubricants.
I have the exact opposite experience using RP stuff.
My tranny doesn't like it, my engine doesn't like it, and neither did my friends engine (it actually started to foam).
RP is just over hyped, expensive crap. They just have good marketing people.
As far as engine oils go, I swear by Lubro/Liqui Molly (contact Bimmersport)... I just got my oil report back from Blackstone labs 2 weeks ago... everything is looking great with the engine wear and oil quality.
And for gear oils, either Redline or Motul fluids.
