Here's how I look at it, tig. If I were buying by the quart, I'd buy RP, since it's cheaper than M1 here in that quantity. If I were buying by the jug, M1 wins in price, by a significant margin. So, if I had something that used a 0w-40 (out of warranty), only one litre bottles are available up here (aside from Delvac 1, but that's another issue). So, I'd probably go for the RP. If I were to run synthetic in my G, which uses 5w-30, M1 wins on cost since I can get the big jugs.

Of course, there are anecdotal claims on the web that claim the opposite, that RP caused excessive wear, discovered on tear downs. I've done tear downs of engines that ran totally on conventional that showed no wear, too. It's all anecdotal.
I think OVERK1LL's point, and one that should not be overlooked, is that M1 has a certain flagship oil that has more builder's approvals than any other lubricant on the market - their 0w-40. The only thing I can think of that comes even remotely close is GC.
I don't doubt RP 0w-40 is a great lube, and I've used it, and loved it. Heck, the guy who has my old Audi now - I told him to run RP 0w-40 for an annual OCI or at least 10,000 miles. He's a synthetic fanatic and that's his cheapest option, since a 40 grade is best for it and he won't hear of Delvac 1 or Rotella synthetic.
I wouldn't use it in a brand new Benz, since it doesn't meet the specification. I wouldn't use it (or M1 0w-40 or GC) in my G, since it's under warranty, and doesn't meet the requirements.
Like I already said, I don't think XOM worries much about RP as a competitor in the PCMO market. RP is probably a far bigger competitor to them in the industrial lube market, where it's probably a fairer fight and a more apples to apples comparison.
Fantastic post
And I've heard (and not just anecdotes) about extremely good durability results with RP's industrial products. I may be wrong, but they seem to have put a lot of effort into this area. But then, they also seem a lot more popular in this area as well. And this sort of ties into my "manufacturer relationship" point that I'm sure many will dismiss, but when you have a lot of high-profile adoption/usage of a product family, I DO think that says something about the quality of that product. And that goes for ANY lubricant. This applies to XOM's products in racing circles and I'm sure it applies to RP's industrial products, SOPUS's aviation products....etc.
And your point regarding my allusion to M1 0w40 is also spot-on. A lube doesn't get that many certs and approvals being mediocre. Mobil has the CAPABILITY to make the best lubes in the world. Apparently many took that to mean that I think they do. Nobody is the best at everything.
