update
Turns out I mis-ordered and it's not a Denso with ND-OIL 8, it's a GDP with PAG 46. So the question for me is moot. But assuming it gets answered, the answer may help somebody else. Or even me in a few months/years if this GDP compressor fails. So I'll leave it here.
/update

I'm planning to install a new AC Compressor, condenser, seal kit, and expansion valve in a 2006 Honda Ridgeline.

The (OEM) Denso compressor was shipped pre-filled with ND-8.

Was going to pick up a small container of oil to lube the new seals with. But now know that ND-8 while a PAG 46 oil, isn't the quite the same as the standard PAG 46 at the local auto parts store.

So I'm wondering if it's ok to use standard PAG 46 to lube the seals. Or if I should pour a little of the ND-8 out of the compressor and use that; pouring any leftover back in.

Or do I bite the bullet and order ND-8 (or apparently ND-12 see below) and wait for it to get here before tackling this?enter image description here

GM specifically states not using pag oil for ac o-ring lube. R12/mineral oil only. Mineral oil does not absorb moisture. Aluminum corrodes. Your choice to do it right or accept long term consequences of incorrect repairs, the leak no one wants.
