I will keep all of AF updated...So I now know the compressor still works

part of my job was to repair a/c units on large transit vehicles,,
this seal in the compressor requires oil for proper sealing..when the oil is low the r134 comes out quickly...up north during the cold months with a low oil level the seal dries out ...by by refrigerent..
like I stated before do not use sealers of any kind and adding pag 150 is the correct oil for THIS vehicle ....
it is better to be at a low charge than having too much r134 as the pressures will damage the compressor ,,,the compressor must never compress liquid refrigerent at any time or its over..
