Agreed. It's not the most cost conscious purchase. For people buying based on pricing, Motorcraft brand motor oil will not be an option.

Agreed.
For decades, I've seen the city's fleet get oil from a drum. The oil filters came on a pallet. Purchase contract specifies that oil & filter must meet OEM spec grade. From there, it's whatever the process is to award the contracts to various bidders. We'll assume that every city vehicle is driven hard, abused, and no city worker cares about the car they are driving. Parks & rec, public works, school district, police, fire, building inspectors........I've never seen a blown engine, because the filter and/or oil was bad. Even in a police car, under pursuit conditions, those engines never melted and the filters never burst under load.
Expected service life is 5 years, where these cars have hundreds of thousands of miles. Other things go wrong. Transmissions. Brakes. Steering. Water pump. Thermostat. Door latches. Seat belt buckles. Driver seat mounting brackets. Fuel pump. Fuel filter. Emissions components. Paint fading & peeling. Multi-function switches. Door unlock latch handles. HVAC system. Suspension. You name it. It breaks. But never an engine meltdown because of cheap oil & filters.
