A/C compressor oil question

[My Nameis]

I’m curious if the compressor oil and refrigerant are both pumped through the entire system or not.

I know they sell refrigerant bottles that have oil mixed in so that leads to me think they do? If not how does the oil stay in the compressor when filled using those mixed bottles?

On most of the new systems the oil is carried by the refrigerant.

On all systems oil leaves the compressor via refrigerant oil mix. As oil leaves it must
come back to the compressor via refrigerant oil mix.

So does the oil go through compression/evaporation as well or it’s separated through out the system?
