R-22 Capella oil (aka no wax no detergent, otherwise like in your car)
R-410A POE
You don't know if you have 22 or 410A? Then you need to do a LOT of reading on the web, here or other places before asking inane questions (as ACH implied, but too nice to say right out <G>)
Have never heard of a mini-split having one of the old type unsealed reciprocating compressors, but if there is such an old beast, it surely uses Capella oil. (e.G. 1970s chrysler compressors that have a crankcase oil fill plug)
