Was researching oil used in the new Ford GT. Owner's manual says to use a new oil - Castrol Edge Supercar 5w-50. Looking at the specs of this oil, it meets Ford WSS-M2C931-C, which is the same spec for the GT350. Looks like this Castrol oil was formulated specifically for Ford.

Doesn't appear to be on store shelves yet ... maybe at Ford dealerships.
