I've said it before and I'll say it again-the only thing I would ever consider using as an automotive refrigerant is R12 or R134. Neither of these is flammable.

I've read this before and always get a chuckle. Folks are over-concerned that the 2-3 lbs of refrigerant in the AC is flammable, but riding around with 20 gallons (140 lbs) of flammable liquid in the fuel tank doesn't bother them.
