This is my new post, I just flushed the whole A/C system after replacing the compressor. I unplug the 2 hoses to the compressor and flushed both . There was a greenish fluid coming out, same color as it was the compressor oil? or A/C oil? So the system is totally empty now and holds vacuum at -30. Can someone here tell me if I need to add oil? The compressor came filled from the factory with lubricant, is this the same oil? This is for my C70 2011. Thank you everyone

Sorry, but hvac is not my strong area. Many owners never go beyond replacing/adjusting the clutch since you need dedicated equipment to do it correctly. Yes, vaccuum pump and refill gauges with refrigirant cans can help, but it is not a proper machine which usually is around 5k(way more for dual refrigirant set up).
In terms of oil. I believe that every new or refurbished compressor should come with oil inside(peg) based on type of car amount of oil can be different (same compressor can be used on different cars). One usually drains all the oil prior to instalation and measures it. Alternatively dumps it out and fills with predetermined amount of fresh oil which is correct for your car.
You are describing system " flush" here..not sure you did what manual would demand..(correct ac flush fluid, lines, condenser...). It is hard to suggest something since we dont know the extend of damage that old compressor did. If there was no contaminants in the system-all good, you can try to play with removing compressor, filling it with proper amount of oil, replacing dryer, vaccuum, recharge with proper ammount..But if there was contamination- pain..all basically needs to be removed, washed with min spirits, replace expansion valve, replace dryer, and the rest as above..

Vova, thank you for taking the time to respond. And yes, I did all of that. I think in this cars the expansion valve is now the orifice tube which I replaced. and I took of the dryer and did a special flush on it. It's going to be hot here, NC, hopefully after I fill it up with freon will get it back to work. Thank you
