I read the EPA listings and descriptions of approved fluids, and several other official discussions of AC fluids. Seems that except for those who sell fluids other than R134, there is universal agreement that when changing over from R12 one should go to R134. I recently changed my VW Vanagon GL Campmobile waterboxer 2.1, original factory air over. I asked several techs about alternatives, and all told me the only fluid I should consider was R134. I asked about cooling efficiency. Every one of them told me that given the exceptionally large evaporator that the vanagon has, there is no problem with it running cold enough, unless there is a leak, in which case one needs to fix the leak. I have read that no car manufacturer recommends any change over except to R134.
I can say that with my system, with no detectable leak according to the shop that changed it over (pulled vacuum over a weekend, no change in vacuum reading), it runs quite cold. I did have the shop change the dryer, flush the system, change the oil, change the fittings, then recharge with R134.
