Supertech today, on the Walmart website, is about $6 less than the cheapest Mobil 1 5 qt container. I like Mobil 1 fine, but you are asking us to take on faith that it is made with "higher quality ingredients." Is that true? Who knows?I don't get the rationale of buying SuperTech, when for the same money you can do better, like Mobil 1 better. And Mobil 1 uses higher quality ingredients compared to SuperTech.
