A sample to Blackstone would result in a match between almost all known brands, potentially again, since this probably wouldn't even happen..
There is not enough accuracy or enough information with a $28.00 analysis to deny a warranty.
Obviously, if the owner says he used Magnatec or whatever, the extra moly, boron, and particular Mg/Ca mix in Amsoil would correlate with Magnatec or any other known oil that has the Ford WSS spec...

Ridiculous. .... I used Magnatec as 1 possible example, not Motorcraft. And then I said "...or any other known oil". What made you think I said Motorcraft specifically?
Could be you don't know the WSS-M2C946-B1 Ford spec is available on multiple brands(??), not sure why you would ask me that.
So keep arguing over something that's not likely to happen anyway. The odds of ever getting to an oil analysis are slim to none.
