I agree. There is very little information about this spec on the internet. Such as, are there viscosity requirements, additive requirements, etc. Many believe that any liquid that will pour meets the specification.
I suspect this is simply a money-making venture, if an oil bottler has to pay for testing to have the certification put on the bottles. Who tests the oil? Chrysler or an independent lab? What about MS-6395 goes above and beyond what API SN and/or ILSAC GF-5 already covers? I used to be all into manufacturer's oil specifications (like this, like any of Ford's specs, GM's dexos1, any of BMW's LL specs, etc). But anymore, I appreciate when a manufacturer simply calls for an API Sx and ILSAC GF-n oil. It makes it so much easier for the consumer (and for bottlers).
