quote from Motor Magazine article:

Japanese vehicles. This is a problem area, because Japanese-spec coolants have never been sold in the U.S. aftermarket and history says conventional American coolants work well in these vehicles. Toyota research indicates the new extended-life coolant contains phosphates to protect the water pump, and DexCool contains no phosphate. Honda has said it will not use a coolant with 2-EHA. So both carmakers exclude DexCool. Best solution with aftermarket coolants: Do a complete coolant exchange, and replace the Japanese OE coolant-conventional or extended-life -with conventional American or G-05.

So I guess I'll have to top up with fluid from the Honda store till warranty expires. Then I'll make the "switch". I am reluctant though, as engineers have given this much thought.
A blind change may not be a wise move based on the laws of chemistry!

Thanks for posting the link
