John, The orange was formulated to GM specs and is recommended by GM for
late model engines. It has Dex Cool which I believe is similar to water
wetter and supposed to cool somewhat better than the green. I have been told
not to mix them. I have been using the orange in my old cars for years
without problems. I have not heard of or had the problems Gene mentioned,
but I can't say that the Or. is any better or worst than standard green anti
freeze. It mainly ended up in my cars for consistancy purposes.

Hi,
My daily driver is a 96 Olds 88 which I bought with ''bad head gaskets''
but turned out to be a deteriorated plastic upper intake where coolant
went
thru it to cool the egr vapors. After talking to my mechanic buddies I
found
out the orange will attack plastic and gaskets alike and the only thing
they
put back in cars they do is the green stuff.

Is there really any known difference between orange vs. green anti-freeze
(other than the color)? I have the El Camino using orange and the MR2
using
green. I know you're not supposed to mix them. Just wondering if I should
stick with one or the other. The green seems to be more commonly
available.
When my friend Rick & I built the EC engine we used orange just because
it
was what he had in his shop. He also gave me a spare gallon to take home.
I
was running straight water all summer because of my heater core leak
causing
fumes to enter the cabin. I have since bypassed the heater core and put
more
of the orange stuff in.
