For the 1.5L Ecoboost, here's the text related to engine oil:

The engine has been designed to be used with Castrol and Ford Engine Oil, which gives a fuel economy benefit while maintaining the durability of the engine.
Adding oil: If you are unable to find an oil that meets the specification defined by WSS-M2C948-B or WSS-M2C913-C, you must use SAE 5W-20 or SAE 5W-30 that meets the specification defined by ACEA A5/B5.
Note: Do not use more than 1 L between scheduled service intervals.
Using oils other than the one specified can result in longer engine cranking periods, reduced engine performance, reduced fuel economy and increased emission levels.
Missing Image
We recommend Castrol and Ford engine oils and lubricants.
Note: The "missing image" text is where a big, ole Castrol logo appears in the manual. I added some of the bold and italics.
