I drove my Park Avenue for 7 years with R152A (keyboard duster spray) as air conditioner refrigerant. The results were very good. The old and worn compressor got no worse and provided many hours of ice cold A/C in spite of its noisy operation.
Finally, I decided to replace the compressor with a new one and did a teardown inspection of the old one.
