A few years ago , we had a 2002 Buick Century . I replaced the GM V-5 compressor , accumulator and orifice . I was told to use PAG oil . Can not remember which viscosity .
When it gets warmer & will either have to replace the V-5 on a 1996 Chevy Lumina 4 door sedan , or replace the O-rings and seals on it . Will have to look it up , but I suspect it came from GM with PAG oil ?
God bless
