Still use it, but not in my cars.  It is used in our cooling system for an
air compressor at work.

Christopher, you have to be careful here.  Industry terminology is changing.

Almost all of the "standard" ethylene glycol coolant I buy is now called,
"Long Life."  But it is not the same as the "Extended Life" coolant that is
becoming so common.  Both Peak and Prestone have both.  The "Long Life" is
actually just ethylene glycol with a couple of additives that won't hurt
your radiator.

At least in my area, the choice is still good.  And I get the impression
that the ethylene glycol anti-freeze that is out there is better (with some
of these additives) than it used to be.  To me, there is still nothing like
changing your coolant every Fall.
