1988 Pontiac Firebird V8 Two Wheel Drive Automatic

Hello, I am looking for the correct oil charge for the a/c system on my 1988 formula if I am using R-12? I have plenty left so this is what I am using. Any help would be appreciated.

All the manual states is the refridgerant charge is 2.25lbs, as far as oil, it's add what is removed. By measuring!

The book calls for 3 fluid oz. 90 ml of fresh 525 viscosity refrigerant oil if the oil in the evaporator has been drained.
