I want to discharge and refill the A/C. How much oil I need to add and what type. Of course I will recover the old Freon?

Thank you

Good afternoon,

If you are not replacing anything, then just add one ounce of Pag 90.

Why are you doing this procedure?

The A/C is not cooling well. On the tag it says ND 8 oil. I looked online it says equivalent is Pag 46. Is it right?

Pag 46 is okay to use. 46 and 49 are almost the same and mixing them is not an issue.

No, just get the Pag oil. No additives needed. The Pag has all the additives it needs.
