heya, so, my dad is an engineer and gets really excited about stuff like this. Have any of you heard of this stuf yet?

Autocool's Hydrocarbon based (HC vs. CFC & HFC) HC12a refrigerant is
totally
compatible with all systems, seals, hoses and oils, is 12% - 32% more
efficient than R-12 and 20% - 40% more efficient than R134a, non-toxic,
non-ozone depleting, is lighter than R-12 (1 oz of HC12a = approx. 3
ozs of
R-12) so it reduces compressor load up to 40%, thereby extending
component
life and increasing gas mileage by up to 5%, is relatively cheap and
has no
adverse reaction to moisture.

It is also not controlled by the EPA, so anyone can buy it and it is
made in
the USA !

That's pretty interesting, especially for older vehicles where R-12 refrigerant is cost prohibitive.

My system is still functioning properly with no leaks but I would read up on this stuff if my system needed servicing in the future.
