Question

Answer 1

Walmart does not make oil, some other oil manufacturer (Havoline, Valvoline, etc) makes walmart oil. The bottle says supertech but anyway another manufacturer makes it. For example if you go to walmart and tell them to change your oil then you get the walmart brand. As far as the 5W20, if it is written somewhere on the engine or in the owners manuel to run a 5W20, then you need to run a 5W20. A 5W20 oil is strictly for fuel mileage in the newer cars. Now, anything synthetic is ALWAYS going to be better than non synthetic for both engine wear and FUEL ECONOMY.  

Answer 2

Check your owners manual for the recommended oil viscosity and certification for your cars. If the wal mart oil fits the bill as long as you change it on a regular basis there should not be a problem.

Answer 3

oil is oil using the right weigh more important ive been driving 40 yrs and have yet to tell any differant between oils what matters most is you have it
