2- Why you want to change it to Propane? You already have R-134a system that is already cheap. Stay with it. You should be fine.

You can add hydrocarbon refrigerants to either oil mix,
AFAIK. You just can't mix R12/R134 with the lube intended for the wrong one.
There are lots of people who've installed Dura-Cool (which is about 70%+ propane) directly into 134 systems, with zero problems whatsoever. So if something that's 70%+ propane doesn't cause any problems with the synthetic lube oil used in 134 systems, then I don't see why 100% propane would cause any problems either.
