Definitely a concern of mine with a turbo...
AFE and EP have more PAO than Mobil 1, but that does not explain Mobil 1 High Mileage (unless it does too).
Just 2 Mobil 1 and Mobil 1 Advanced Fuel Economy grades, not HM nor EP:
Mobil 1: 5W20, 5W30, 10W30, 0W40 ...
Mobil 1 Advanced Fuel Economy: 0W20 and 0W30
If there are Mobil 1 0W20 and 0W30 then AFE are special, as I see it they are just marketing ploy of Mobil.
