    I am going to convert my 89 from R12 to the new R134a, what oil should I put in my compressor? There are two kinds I could use, Ester oil and Pax(sp?)oil. Which is better for the GM compressors? I am also replacing the compressor with a new one.
    Thanks

    There is only one oil compatable with 134...you have to use the correct one. I can never remember which it is, but check out this site for info, they have a good message forum. http://www.aircondition.com You can also search for this topic on this site....it's been talked about at length....Good luck!

    USE ESTER OIL. A FRIEND OF MINE HAD HIS CONVERTED AND THE GUY THAT DID IT SAID IF HE DIDNT USE ESTER HE WOULDNT CONVERT IT. ALSO FYI, ANOTHER FRIEND PUT A MIXTURE OF R22 AND 134 STRAIGHT INTO HIS SYSTEM AND IT WORKS GREAT.NO CONVERSIONS WERE NEEDED. GOOD LUCK
