Tanama,I forgot to add that in my case since I drive so few miles, a trade off with OAT technology is that the rust inhibitors 2-EHA and sebacate always take thousands of miles before they become fully effective at their job!!!There is trade offs in all versions of coolant technology!!!!!

sayjac,thanks for the reply..I was looking for more real world use since ashland is a little biased...I thought this fourm might some users who have used Zerex..

First,you can use a test strip or send a sample to a lab for more detail...Also one would change it out before it became discolored..Zerex appears to be the same original green except with longer life..What you have to watch for in the green is the deteration of the rust inhibtors, if you wait...

I have observed most of the original green coolant such as Peak and most others have 2 year/24000 mile life span!!!However,Zerex original green claims 5 year/100000 mile life span.I have been using peak in my 1999 Ford Ranger and have changed it every 24-30 k miles.My test strip indcates it's...
