Shop gave up on AC system (Page 3/3) RWDPLZ OCT 27, 08:25 PM Oil on the orifice tube is normal. Looks nice and clean. 3 12oz cans will generally get the job done. Drive it around with airflow through the condenser and see if the vent temp gets down to 40 F. Check gauge readings again after a drive, high side should get over 200. Make sure you ask the shop if they added more oil, and what type.

Honestly Im gonna blame the gauge, its a rental from autozone.
