No more DEF than I use in a year's time the small amount of money for the new and improved "Platinum" DEF is nothing and I will begin using it until proven otherwise.

I'd say you have that backwards, I'll begin using when they prove that it works not the other way around.............

Nope, I have it forward. I would rather use it and later find there is no benefit than to not use it and find the continued deposits required costly repairs to the emissions system.

To each his own.
