    Lots of options out there.

    I like MO49 primarily

    or

    401a for medium temp applications

    401b for low temp applications

    If I was going to change the compressor I would convert to 134A. While u have the compressor out just fluah it with rx11 and pull a good vacuum.

    Why not 134A it's apparently using a txv most of the problems I have with 134A come from cap tube systems and waxing I have the same issues with all refrigerants using poe oil and cap tubes.

    I would say 401a but to each his own. I'm not a fan of hot snot or 134a. I've had issues w/ cap tubes & TEVs on anything running w poe including rtus .. We all know what the high temps do.
