Do I need to add Pag Oil to accumulator?

[Del1650]

Hello, I am working on the AC system on a 1997 Pontiac Grand Am. I have already replaced the compressor because it was bad, it is pre oiled. I also got a kit that came with an accumulator/dryer and a bunch of gasket and o-rings. I have seen mixed answers on whether or not to add oil to the accumulator. What do you guys think? Add oil to the accumulator or not? I already have the oil, and will add it if needed. And I am okay with adding oil if it is not going to harm anything (too much oil combined with oil in the compressor etc...)

Thank you!

If the compressor come with the full amount listed for the system, then none needs to be added. If the compressor has less than the full amount the system calls for, then add the difference to to accumulator

Ok that helps, thank you for your reply!

Note that personally I've drained and verified the amount of oil included with a new compressor. I wouldn't leave that at trust.

Valid point. As I am always starting with a "dry" compressor, and the A-6 will safely hold the full 10 oz charge, I put the full in the compressor.
Most accumulators have a small "aspirator" hole in the bottom of the U tube (internally) to draw any oil from the bottom of the accumulator.
If the system hasn't blown a hose and all its oil out with the escaping charge, a full compressor charge of oil is all that is needed. The oil circulated with the refrigerant and some pools in low spots.
I've always felt that a little too much is better than a little to little when it comes to oil, but going too far in either direction can be fatal to a system.
