I did call the shop and they said, "we used whatever oil came with the conversion kit."
Of course they never bothered to post a conversion label or even change the o-rings to R134 compatible.
I'm just going to go with ester. This a/c fix has consumed my life for two weeks and I'm done.
Tomorrow I'm pulling a vacuum and recharging.
Thank you to everyone for their help.
