This is what I asked them in my most recent email: "Does the Maxlife Coolant contain any silicates, phosphates, borates, nitrates or amines. And it is it a extended life coolant and does it provide the same diesel protection that G05 does?" We will see what they say.
Here is the response they sent to the question above:
"Most Recent Update:
Thank you for your question. The MaxLife Coolant contains each of these additives that you have mentioned, except for the amines. Please note that Valvoline recommends the universal use of the MaxLife Coolant for all makes and all models of vehicles designed to use an ethylene glycol based engine coolant after ASTM D3306 and the product is suitable for use in gasoline and diesel applications, however it is important to note that the product does not contain Nitrites for complete diesel protection as the actual OEM recommended coolant or Zerex G05 in some cases. This coolant is simply produced to provide the customer a safe use of a coolant for universal use after the vehicle is out of warranty, however we strongly recommend that you follow and use the recommended coolant specified for use in your vehicle if possible."
I will say I give Valvoline/Ashland an A+ with regard to responsiveness.
