I own a 2016 Ford Escape with the 2.0L Ecoboost direct injected engine.I do mostly highway milage and run the oil for a 6K OCI.My question is since all direct injection engines have a problem with carbon build up is this worth having over any other type of fuel injection?The cost in the future to clean these engines will not be cheap.Ford has no "factory"approved way of dealing with this issue.My dealer I believe uses BG products but it's not Ford approved.Joe
