I am a first time poster, so please forgive my ignorance. I have been told that private label oil such as "NAPA" and "Parts Master" brands are made by Valvoline. The salesman says they are equal or superior to the name brand product. He says, they sell for less because they do not include the cost of a large advertising budget.
I am somewhat skeptical and would appreciate any advise I can receive on this. Thank you in advance.
