How do you put oil in the A/C Compressor?

My A/C comp. makes a little noise when it's functioning. I read that you have to put oil in it. How do you do that?

You don't just put oil in without 100% rebuilding it.
However, most recharge cans have a small amount contained in them.

you're suppose to put in the oil when u put in the freon that's how the mechanic did it last time i had a recharge
