specifically it's not the work you do your self.
It's more the brand of part you buy. Magnuson-moss is mostly about you using replacement parts not sourced through a dealer or manufacturer.
Ie you changed your oil and didn't use motorcraft oil and motorcraft filter therefore we void your warranty.
FYI, you don't have to use Motorcraft Oil to keep your warranty. Even says so in the manual:
"Your engine has been designed to use engine oil that meets Ford specification. It is also acceptable to use an engine oil of recommended viscosity grade that displays the API Certification Mark for gasoline engines."
All you need is the same viscosity and the API seal.
