AMong WRX crowd Rotella T6 is popular and among 1st gen VW TFSI owners. Reason for VW owners is fuel dilution and T6 is pretty heavy at 14.2cst.
BUT, you are running DI engine with two turbo chragers. You want low NOACK oil. T6 is 12.6% and Castrol 0W40 that you can get in Wal Mart is 9.1%. T6 is oil made for diesel trucks, and you will feel slower spool of your turbos (actully you will feel that with any W40 oil in your application because engine is specd. for lighter oil).
However, FORD ecoboost engines are known for fuel dilution. So Castrol 0W40 or M1 0W40 would be really good choice for you. My preference would be Castrol 0W40. It is $26 at Wal mart for 5qt jug.
