I'm running Motorcraft 5w20 full synthetic in my '12 Focus. It's good stuff. Allows you to run cooler and reduce engine deposits. Though I've seen that a lot of members prefer Castrol.
Reducing engine deposits is key in a GDI, as fuel (w/ cleaning agents) is not drawn through the intake valves (only air).
