I'm reading that R12 is quite expensive. R134 is a substitute. What are the ramifications? How much cheaper is it? I'm no longer getting any cooling out of my AC. Have never had a problem with AC (except engine tends to run hotter when it's running and car is idling, which I guess is another subject). Mechanic suspects its simply out of refrigerant. It's an '89 735i.
