Weather muust be getting warmer when the annual R134 threads start to come out... Not just DeLorean -- R12 usually outperforms R134 in any system designed for it. R134 works (quite comfortably IMHO), but R12 does work better (my Lincolns, for example, will loose their refrigeration cycle sitting in rush hour traffic with just the engine fan at 500 RPM. Not a problem with electric fans of course). The issue is cost and convenience. R134 is available to the general public at any parts house, as low as $2.50 a can (case quantity). R134 tools are also more readily available. R134 responds well to non-professional mechanics. If your system leaks, losing R134 is less traumatic than losing R12 (both to your wallet and to the environment). If I had only one antique vehicle to maintain, R12 would certainly be the way to go. But with a fleet, the newest of which is 19 years old, R134 makes more sense for me.
