AC Condenser Question

AC Condenser Question
My AC is blowing hot air and I've come to find out by my own diagnosis (as well as a technician) that I have a hole in my AC condenser. Currently my low pressure reading is 0 psi.
I've recently purchased a new drier, condenser, and O-rings as well as 2 cans of 12 ounce refrigerant.
Once the condenser is replaced, I'm going to perform a vacuum test to make sure there are no other leaks. If there is, I'll head back to the drawing board. *IF* there are no leaks, I plan on doing vacuuming my system to get rid of all the moisture currently in there.
I've found a couple write-ups on how to replace an AC condenser step-by-step, but one thing I'm curious about is...
Do I need to add any oil? It's my assumption that I wouldn't since all the oil would be in the compressor and that all I need to add is just refrigerant.
Thanks in advance!

From everything I read, your MDX takes PAG 46 but you should get that confirmed. As far as I know, all 134a Denso compressors require PAG (46 or 100). Make sure you buy the good stuff - DEC. It is double-end-capped which means it is more stable chemically because the ends of the polymer chain are unreactive.

Thank you thank you for answering so far.

Add it to the condenser. One more minor point: Lexus advises that you do not use PAG to lube the O-rings because it is hygroscopic. I assume Honda says the same thing since it is a general practice. Use a little mineral oil. My best advice to you is to get a genuine factory service manual.
