I know you have old tractors and don't like to change coolant every two years anymore than I do, so what brand of long life coolant do you use?
I ask because as you said the label " .... is largely sales hype written by a marketing grunt not an engineer or chemist."
The last time I bought anti-freeze, of all the brands they had, only ONE was clearly labeled IAT. Some long-life brands were probably ok, but is was impossible for me to tell.
