I am looking for an oil recommendation for my wife's 2016 Ford Escape. It has the 2.0L Ecoboost engine. I changed it once with Amsoil Signature, but after reading here about Amsoil's formulation change, I have my doubts. I don't really want to pay a premium for oil if it isn't what it is sold to be. Would Redline or Schaeffer's be a better choice? I know direct injection turbo engines are fairly hard on motor oil, so I want something that will make this vehicle last. Any ideas or suggestions would be greatly appreciated.
