Well the ethylene glycol in antifreeze does not "wear out" - what does get
used up is the corrosion inhibitors and pH buffers. I can only guess that
the Type 2 has better additives which last longer and since it is premixed
there is no danger of getting hard tap water in the "equation". If you
consider that the cost of the Type 2 premixed is about the same per gallon
as the old stuff, the total cost is about the same: twice the cost per
change but you get double the mileage between changes. BTW the Type 2 has
a very distinctive smell... kinda marzipanish.
