All API (or other spec) oils that meet the specification that your vehicle calls for are equal and none can be proven to be better at everything, at any price.
So pick any oil from Walmart or any other retailer that meets those specs at any price.
Ex. your asking for the best oil for less friction which is one objective out of dozens. What if the best oil at reducing friction (which can not be proven) allows rust to build up in the engine while the vehicle sits around during the winter? Would you still want that oil?
Just go with the proper spec the manufacturer of the engine recommends, trust them, then know a heck of a lot more what is required and its not the oil that saves an engine, its engine design that makes it last, so again, choose based on your owners manual.
I know we ALL think we know better or want to do better for our engines BUT we are only motivated to use a specific oil by oil company marketing and not reality.
Decades ago it was a different story, new oils that need to meet a spec are all the same, only a handful of companies now make these additive packages for all the oil brands.
