I guess conventional wisdom would say the first ingredient listed is what makes up most of the solution.
The first ingredients are water and ethylene glycol and this stuff is bright green.
The 5 year/150,000 mile claim on the front has me nervous, though as I know it's synonomous with DexCool like products.
You just topped it off, so your engine is not going to dissolve overnight. NJSTRN-QT1 is the last ingredient and it might not be a 2-EHA, we just do not know, relax.
How old is the original coolant in the car? If 2 different chemistries are mixed, do not expect coolant to last 5 years like pure G5 does. If it were my car, I'd do a couple of radiator drain and refills with Mazda/Ford coolant before the winter and plan on doing 2 more next summer, after that you'll have 99.9% approved coolant in and should last 5 years.
