I agree but just put out the warning that, except for a few oil vendors - SHell T-6 not being one of them, Ford has come out saying to keep using CJ-4, stay away from CK-4 certified oil. The newer oil is not approved for the 6.7 liter engine except for the few. More are being approved as time goes on from what I've read.

No personal history here, nor have I read of any one actually having problems, just what I've read from Ford and other sources.
