I used pennzoil that advertised being good for turbo charged engines. I only got it because it was on sale. The Meijer brand I used in the previous oil change worked well too. The only thing that hasn't done great is the first oil change with motorcraft. It could be due to engine break-in but after 9k miles you would hope that would be a little more resolved.
I increased the mileage change again to test the theory on the fuel issue with ecoboost engines. This was closer to 9k miles.
