Nothing matters. People will always use their own reasoning for the oil of their choice. That is why you constantly see on forums, and in real life, someone using an oil weight which is different than the one specified in the owners manual. People who are brand loyal will spend no matter how much on their brand of choice.
I drank the Kool Aid. I used to pay more for boutique oil brands. I don't think any of the high price oil made any difference.
Filters do make a difference. Cut them open and you can see how some filters are made better.
Amazon.com oil will be just fine for the price. It comes from the same factory as other no name brand products.
