All the same I don't know any Ecoboost owners that use Premium and some people have reported here that they have compared performance on the two fuels and actually did better with regular.

Which tells me you cannot trust the reports from many consumers. If one does not understand how higher octane fuel might help in that engine and will not go by the owners manual, then I don't care to hear what those folks have to say.

Ford does NOT require or even recommend Premium fuel. My own experience using nothing but the recommended 87 octane for over 100,000 miles, much of it trailer pulling, is that there has not been any engine or drivetrain issues.
