From the web searching I’ve done it appears that Prestone makes Supertech coolant. From what I’ve found the two formulas do look different as the Prestone shows to have phosphates as part of their cor guard additive package. Also the Prestone is advertised as a ten year coolant and the Supertech as a five year.
If my assumptions are correct then I feel the Prestone is worth the few extra dollars a gallon for my vehicles. Has anyone found information that would contradict that?? Or know anything that I may have missed?
