My whole A/C system is flushed, and i rebuild the compressor myself.
So there is no oil in the system.
Now i need to add 120ml oil to the system.
How to do this the best?

I'm afraid adding 120ml (4oz) oil to the pump, it will hydro-lock it?
So i added 60(2oz) oil to the pump.
And i want to add the remaining 60ml to the rest of the system.
10ml in the dryer
20ml in the condenser
20ml in the evaporator
10ml in the A/C hose.

Is this a good way to do it?
