A lot of folks enjoy the low prices of Super Tech, Kirkland and other store brands that are manufactured by Warren Oil Products and/or Warren Distribution. Many mention the fact that that they are not paying for marketing for those brands. I’ll give you that but, what about research and development? I have looked at the websites for both companies and see nothing mentioned about research and development, running an engine lab, etc. My question. How do these companies develop their formulations? Do they live off of the work of companies like Exxonmobil, Valvoline and others?
