Most new compressors have enough oil in them to be fine. If you had a large leak and you have lost some oil them add 1/2 once and you should be fine.

Please let us know if you need anything else to get the problem fixed.

Here are the capacities from the service manual
Polyalkaline Glycol (PAG) Refrigerant Oil System Capacity
V7 8.96 fl. Oz. (265 ml)
HT6 7.98 fl. Oz. (236 ml)

I live in South Florida and have worked at shops that do nothing but A/C. There is no specific amount to be added. It ALWAYS depends on how much is removed.

This guide will help you as well.

I've researched this thing up and down the internet and the best I can figure is 2 to 2.8 ozs. I received a bottle of refrigerant lubricant with my purchase as well as a bottle with the receiver dryer. I haven't even researched that yet. I do appreciate your time and response. Thank you.

I would expect it will need more than that. A general rule of thum but by no means accurate is 4 for a new compressor and 2 for each addition component replaced but that includes flushing the condenser.

Your system holds 2 oz 2.8 max I have done a/c work trucks and cars for 23 years. Also you should be able to get a kit with 134a with the right amount of oil in it at any parts store. There should be a tag under the hood that tells how much 134a the system takes
