You may be right. All I’m saying I I use Motorcraft Full synthetic on my last 3 Coyotes.So not to start an oil argument, if it reads full synthetic, it’s synthesized conventional oil with a changed molecule. If you wanna run a true synthetic oil, the bottle needs to read synthetic oil like Royal Purple or Amsoil. . Both about the same and give outstanding lubricant properties.
20+ oil changes and they all ran tip top
