RP has not been around very long, and its ad copy reads like a marketing man gone berserk, rather than a sober engineering oriented company. I do not know any of my friends who are tribs or SAE members who use it.
On their site last year, I found a huge "oversight" - they were hawking one of their non-synoils as a synoil - it was eventually "corrected", but no banner headline to clarify for those who had already bought into it - they probably still do not know.
I think any oil company that has to get a trade or service mark for its purple bottle has issues.

ive been running royal purple for over 6 months and it's been doing fine, but i just have to change it frequently, no more than 3,000 miles can go by or it starts to lose its effectiveness. i plan on switching to MOTUL. you guys should check it out.
Royal purple in my $13k race motor 20w50 , Mobil one 0w20 in my TL. I work for one of the major oil companies (M@B!L) and can give you plenty of info but in the end it is still consumers choice. CleanCL, you should be able to go longer then 3k with ANY syn oil, if not then you must be tuned excessively rich and the fuel degrades the oil not the oil itself. I can almost go a whole season on RP in my race car (about 100-150 passes) if im just running N/A but with N2O ill only go about 20-25 cause i run it on the safe side of rich
