Are there any house brand oils that people really recommend and/or have a VOA or a UOA that shows a house brand oil is pretty darn good? I am currently using Walmart Super Tech Synthetic just because it is the cheapest synthetic I can find. I have noticed that a lot of stores sell their own oil. Even Sears has a brand of motor oil. I know any oil that has the starburst and the API rating will work. Just wondering if their really is a House Brand that people strongly recommend.
