Peak is out with a new AF with longer recommended service interval. I might not run it as long as rated, but I like the spec sheet description. "Coolant is free of 2-EHA, silicate, nitrite, borate, and amines,...". So description reads like an improved inhibitor version of sub forum favorite, Peak Global Lifetime. Long service interval OAT AF no 2eha. I'll be interested to see availability and pricing of the concentrate. It does come in a 50/50 premix too.
