When mine needed recharged my mechanic told me to stay with the original freon. Yes it is more expensive, but he claims the 134 causes the system to run at a high pressure and causes premature failure. He also claimed that the system will get colder under the original R12 that it was designed to run with vs. 134.

With one of them (?Ester i think?) you must replace all the o-ring seals in the connectors with a compatible o-ring. I believe the other is nitrile o-ring friendly.

Search the archives for my long thread on R134A conversion. There's a link to an A/C chat.
