Default Oil compressor AC

Hi, I have a Van 1997 G10 1500 5.0 V8
The A / C donīt work and I bought a new Four Season 58947 compressor, but I can't find how much oil I have to put on it, it has been preloaded 3 oz, I think it has the Pag46. How much oil do I have to put?
And another question, how much R134A gas should be charged
In Spain, mechanics don't know about Chevy repairs. Sorry for my English, it's from the translator

Charge pressure is usually around 45 psi on the low side.


Get a measuring cup and drain the oil out of the compressor. Just because they come preloaded doesn't mean the oil is actually in there. Sometimes they forgot to put it in. I have experienced this situation.
