Ditto. Stick to good brand names and you are GTG. I usually run Mobil 1 but I have no issue using others.

5W30 full synthetic. Literally zero reason to run anything different.

5W30 Mobil 1

5W30 Full syn every 5k miles.

Looks like most are 5W-30.

I prefer a higher HTHS. With the EcoBoost being prone to fuel dilution (viscosity falling out), plus a tune that increases cylinder pressures, my engine will stay on 0W-40 or 5W-40. I like the extra "insurance".

None of the tuners recommend doing so, so I’ll stick to what Ford recommended and tuners found no need to change.

Mobil 1 FS 5w-30 (euro spec)

Excellent choice as HTHS will be at least 3.5 being a A3/B4 spec.

I switched to that one due to my oil test results on other oils. I will be sticking with it for the foreseeable future.
