I recently read two articles on coolant

https://www.holtsauto.com/prestone/2016/09/29/why-is-coolant-different-colours/
After reading these (especially the 1st one), it is my understanding that the old type coolant with silicon and phosphor is actually good for our engines which is cast iron block with aluminum head, as long as the owner does not consider changing coolant once very two years is too much of a burden. Is my interpretation correct?
Thanks a lot.
