Prestone Extended Life Coolant
Is anyone using Prestone Extended Life Coolant in their Cummins 8.3 ISC engine and is is OK to use or could it cause future problems?

Looks like they have several offerings styled: "Extended Life Coolants".
Here is another extended life coolant that would not be suitable for diesel engines: http://www.prestone.com/enmx/products/antifreeze_coolant/product_list
