MRV difference is meaningless. Love to see them do an MRV/CCV test with both Platinum and Ultra after 10k miles of usage.
If its the 1st SN/GF5 oil, then I would use it over any GF4 OTC oil. Sorry, but as the spec's get more demanding, the performance of the oil only gets better.
The only question I have is when is it coming out in 0w20, 0w30, 0w40, 5w40, & 10w40? Castrol Edge's biggest flaw was lack of weights that I could use.
With API/ILSAC SN/GF5 oils coming on the market hopefully in the next year, I have a feeling that Amsoil, Redline, Royalpurple... will need to rethink their marketing.
Can't wait to see what SN/GF5 brings to Mobil1, Castrol.....and the other OTC brands.
+1
What happens with companies like RP, Amsoil and RL that don't actually pay for the API certifications for all or most of their product lines? Do they reformulate, or, test their products and then change the label to say meets or exceeds the API SN GF-5?
I'm not looking for a flame war, I really would like to know. Seems they would have an easier time dealing with it.
