I use whatever is on sale. Usually ends up being Mobil 1 or penzoil.

I also use the motorcraft FL 400s filter. Cheap on Amazon. Still not expensive at the auto parts store.

That filter is what mountune recommends for our cars https://www.mountuneusa.com/Motorcraft-Oil-Filter-FL-400-S-Focus-ST-Fiesta-ST-p/fl-400s.htm
