I used ms paint ....one quick question, I ordered a new A/C receiver/drier and pressure switch. I am also going to be putting in 40oz of R-12 according to this article:

Should part of the 40oz that I put in be one can of R-12 Oil Charge (One can of R-12 Oil Charge contains 2oz of oil and 2oz of R-12 Freon)?

Thanks,
Adiel
