I've got some pink RV water line anti freeze.
Says not to use in auto radiator / cooling

search. One site says it eats aluminum,
another says no additives.
Anyone want to share the real reason, and
a web site for reference?
Different horses for different courses. There is a reason there are
multiple products. RV antifreeze is propylene glycol which should
NEVER be mixed with ethylene glycol. Yes, there ARE propylene glycol
engine goolants - and some of them are "anhydrous" meaning "no water"
Why not mixed?
Why anhydrous?
Any proof of what you write?
Most automotive antifreezes say not to mix them with non-campatible
coolants. There are so many different chemical concoctions used as
additive packages, some of them organic acids, some containing silica,
etc. Mixing them can have unpredictable results.
Evans coolant is a prime example of "anhydrous" propylene glycol
coolant.and has many advantages over water-based coolants.
It is specified in our Rotax 912 and 914 aircraft engines and is used
in a lot of racing engines and antique car restorations since with no
water the corrosion issues are virtually non-existant. The hotter it
gets the thinner it gets, so it finds leaks that water based coolants
would never find - even with them running at higher system pressures
than the evans product. The lower pressure required for Evans to
eliminate boiling makes it good for older vehicles, and it's high
boiling point makes it good for modified street vehicles.
Plumbing antifreeze is a highly diluted propylene glycol. Without
knowing it's concentration, it's heat transfer and boiling protection
are un-known.
Peak Sierra antifreeze coolant is a water based propylene glycol
engine coolant/antifreeze. Nemco is another one, and Amzoil also
markets a water-based PG coolant.
