I'm probably just over thinking.
I've been using rp for a while. I haven't had issues but I've heard some bad things. It apparently sheers down to 20 weight after 1000 miles or so but then thickens up later on I think...according to an analysis thread I was reading. Some nissan tuners I know really don't like the stuff. They said they have seen a lot of thrown rod bearings. I'm switching to something else on my next change...its probably fine but I've heard too many bad things.
