Mag 1and ST are both blended by Warren oil choose the one with the additive package you prefer would be the most logical I think but then again ,,,,,, Warren is the common denominator in this quiz.
I really like Mag1 products. The company Imown has a decent sized fleet and we have standardized for the last 3 years with all Mag1 products from trans fluid to brake fluid to oils--both diesel and gas. I find they are an excellent product with an excellent price.
Nothing wrong with SuperTech but I'd pick the Mag 1 between the two. Warren clearly views Mag 1 as their top tier branded oil so it is probably the best they make. JMO.
