Pag or Ester oil ?
Installing rebuilt compressor for the air in my 75, instructions are kind of vague. Since i an converting to 134A from R12 should i go with the Ester instead of the old Pad oil ?
Going with 4 oz of oil ?
Suggestions.

One of them is compatible with the old lubricants that may already be in the system...I don't remember which but its what I used at the time.... one will not mix with the old lubercants and can actually cause issues if there's any left in the system.

flush the system with nitrogen then put under a slight vacuum to make sure there are no leaks, plus with flushing it gets all the old oil out of the system so you know for sure there is the correct amount in it, now it will not cool as well as it did with the R12 but you will notice a cooling effect.
