freeze 12&maxi cool any good?

[Dave Glubrecht]

As far as the other R12 replacements are concerned, I would not suggest
using any of them.  One problem with all of them is that they are a mixture
of gasses.  This presents a problem as the different molecule sizes will
leak at different rates.  Most of the older systems leak a little just due
to the porosity of the hosses.  Either pay the price for R12 or convert to
134a, I don't know anything about additives for the 134a.
I do know that I have enough R12 to keep my cars cold for a very long time.

I've been doing some research into QuickBoost
(http://www.qwik.com/qwikboost-press-release.html), which is an R134a
additive. It sounds like it actually works as advertised. Apparently it does
alter the cooling capacity (delta H of vap.) of R-134a. I'm not sure I'd pay
more than ~$10-$12 for something that only claims a 10% improvement though.
Fortunately, it can be had for $11.99 at
http://www.acsource.com/cgi-bin/SoftCart.exe/scstore/p-QT2610.html?L+scstore
+bffu7576+1024373375. The loss of cooling when converting a system
containing R-12 to R-134a is in the 15-20% range, so you might see some
improvement.

Metal surfaces don't need "sealing"; this sounds suspiciously like
the "zmax" crap for engines.  If I recall, Zmax turned out to be
nothing more than mineral oil.

This sounds like snake oil to me too...

Does it increase mileage, make more engine power, and heal small
appliances too? ;-)
