Pennzoil 5w30 Ultra Platinum, 75-140 synthetic in the PTU, 80-90 in rear differential. This is what I have always used in my 2015 all-wheel drive Titanium Edge.
I have 2024 F150 with 3.5 eco boost and use Pennzoil Ultra Platinum 5w30 and micro gard select filter change every six months usually around 3 thousand on miles.
The brake system is all air on those and they have a park brake system that will engage either by pulling knob on dash or when the brake system air supply gets too low it will engage the park system.
That is exactly how it happens. Auto Zone is the same way when I worked there you would find used alternators and starters on the shelves because some of the help didn't care.
