Royal Purple?

anyone ever run royal purple full synthetic oil in the Rzr? i ran it in my sportsman 500 and really liked it cause it lubricates everything internal more than regular oil and being i mud ride if i was to ever get water in my engine i hear it because it lubricates everything more it makes flushing it easier. just wondering thats all… and if so did u do 20w-50 or 10w-40?
