Anyone out there got any thoughts as to the practical life of the Radiator Coolant put in by the factory? (Honda All Season Antifreeze/Coolant Type 2)

The Maintenance Schedule in the owners manual gives a time/distance span as "200,000 kms/10 years, then 100,000 kms/ 5 years therafter, EXCEPT FOR SOUTH AFRICA, AUSTRALIA AND NEW ZEALAND models," but then does not give any time/distance for the latter. (Page 468 of the 2011 issue of the Accord /Accord Euro owner manual)
However the Service Manual says change it at 200,000 kms orn 10 years. (120 months)

Seeing that most advise to change the auto trans fluid earlier than what the Service Manual says, what about Engine Coolant?

Also, opinions on a suitable alternative to the Honda labelled coolant, which would not be made by Honda anyway and is probably way overpriced? (I'm thinking on the lines of something like "Nulon Blue." ..... http://www.nulon.com.au/products/coo...Premix_Coolant)
