As for RP, is there a VOA on it? Isn't it just plain motor oil? I'd say it's no better or worse than $2 SM dino oil. Is there any serious oem style testing to back up claims that RP is a contender? When I buy GC or M1 0w-40, I have a buttload of factory approvals.

I hate to be a cliche', but "where's the beef"?
Well, RP oils for the most part are Group IV PAO based. UNless I have been lied to which I doubt. From what I have seen RP folks are honest to a fault. I guess a few weights/offerings( Racing? )have some Group V. It definitely is not plain motor oil which I assume you mean is conventional? It also is not Group III either if that was what you meant although as PP shows that isn't always a bad thing.
Not to start this up again but factory approval/certifications mean SQUAT other than the oil mfg paid to have their product tested. I wish people on this site would stop putting so much emphasis on, and giving so much credit to, those approved/certified lists. They mean nothing for people who know how to research oils.
What has that certification got to do with it really? The mfg can't refuse you warranty coverage because you used an oil that wasn't on their certified/approved list( for whatever standard you want to apply ). I would think most here would know about the Magnuson-Moss act and the rights they have under that law. No mfg can require/mandate you use an oil that is "certified" to meet their own standard/spec. Just that the oil you use at least meets it. There is a big difference.
As to the actual oil itself. If an oil meets or exceeds a certain standard it does so whether or not it is certified by the mfg to do so. The certification doesn't make it a better oil than one not certified. The test results do and I would think people at this place, of all places, would realize that. So Mobil 1 is on a few( actually most - they really go for it )mfg's certification lists. Does that mean it is better than Amsoil, RedLine, Royal Purple, Penzoil Platinum, Schaeffers, etc...? How does that certification make their oil better? All it means to me is they spent a BUTT LOAD of money to get their products certified( and to be the official oil of many mfg's )and the products would have still been as good if not certified.
As to RP and why they never get certified. What I have been told is they feel the cost for certification is too high. As I stated about the law, what really is the point anyway. The oil is still okay to use. I doubt you see RP ever get certified for any mfg's spec. Not because it couldn't per say but because of the cost involved.
Certification is nice because it saves you having to spend a couple minutes showing your oil meets or exceeds the spec but that really is all it does. Saves a little leg work for the customer. Other than that the certification/approval does nadda for the oil itself. Either it does what you need or it doesn't.
