POE oil is normally used with the newer HFC refrigerents like 410a so if you had mineral oil in the old compressor you could be having a situation where the 2 oils are mixing a causing the cap tube to plug up. Now you can use mineral oil, OR poe oil, OR alkylbenzene oil in an R-22 system BUT not to mix them.

jay,

refrigeration oil is like an alcohol drink, when you mix them you get truble!
