It doesn't hurt to get a can of Refrigerant oil and add that as well.
Make sure it is Synthetic Oil for R134a Refrigerant.
It is usually a very small can, a little bigger than your palm.
It will inject the right amount of oil for your AC system.
Do this FIRST, before adding any refrigerant.




Roadrunner is right that you lose oil, but too much oil will significantly lower the performance of the A/C also.

The only right way of recharging oil and refirgerant is to remove it all (Reclaim the refirgerant) and charge the system with the right amount of both oil and refrigerant.

Overcharging with refrigerant can cause compressor damage and burst hoses.

I am not saying you can't recharge the system, only that there are risks (both damage to the car and personal health risks)if you are not clear on what you are doing.

For instance, if you accidently connected to the high side instead of low (Different connectors, so it is unlikely, put it has happened) the refrigerant can can explode in your hands. Damage from the explosion plus freeze burns can permanently damage you, possibly blind you.

Wear safety glasses and use insulated, inpervious gloves as a minimum. I just had a technician severely burn his hands (Freeze burn looks and hurts just like a heat burn) when the schrader valve on the charging port stuck open when he removed the charging hose. He had leather gloves on and his skin was frozen right through the gloves. He has been out of work for a month and a half now. This is a Trained refrigerant technician. He should of known better, but I want you to be careful and not suffer either.

The process is simple, but consequences of mistakes can be severe.

Good luck.
