The OEM oil is Motorcraft 5w50 full synthetic.

You're gonna need the full synthetic for the temperature resistance at high RPM and the 5w50 to maintain proper viscosity for VCT functionality as the oil degrades with temperatures as well.

Been running Castrol Syntec 5w50 for quite some time now with no issues at 60% the cost of the Motorcraft stuff. I used the Motorcraft stuff until the price spiked in 2012.
