Hi..any good hints/indications or links on the matters of how those two oils behave towards temperature?...to be more specific the case is a retrofit/refit of an older Stal S71, thatīs is supposed to run on R-134a from now on...(previously R-22)
----I wonder if the isentropic efficiency will get better( less heat waste from compressor) since the new oil will have better cooling properties.
..but assumptions will not do the trick, so any help in form of reliable info will most welcome. Best regards AA
