Different oil companies at different times and different regions of the country.
Walmart's synthetic motor oil is typically produced by a company called SuperTech, which is Walmart's private label brand for automotive products. Additionally, some of Walmart's synthetic motor oil may also be sourced from major oil manufacturers that produce private-label products for various retailers. The specific manufacturer can vary based on the product line and supply agreements.

Motorcraft is the OEM Ford motor oil brand.
5.99
They sell a crappy brand called - "certified motor oil".
I prefer Roush HIGH ZINC PERFORMANCE MOTOR OIL.
Depends on what part of the country you are in. It also changes from time to time as they use the bid process to award contracts for oil. So who makes it today may not be true next month. It may very well be a great oil, but I use only major brand oils and stay away from any store brand.
No, but find out the requirements for the motor. Most normal motor oils don't meet manufactures requirements for wear protection.
Depends on where you purchase the oil. Most of their oil is manufactured by Chevron. But in some areas it may be made by some other oil company.
Some Walmart centers install tires for cars. You can get motor oil, anti-freeze and transmission fluid at Walmart.
Any major brand synthetic oil.
As long as it is the same grade of motor oil the brand name should not matter.
