GM V-5 Performance Test 

Baseline performance established using Delco 15-118 lubricant.  1.5 oz of ICE 32 added after running baseline and all tests were duplicated.  All testing was performed at Jacob Sverdrup, Amherst, NY, USA.

 Summary of test results of baseline vs. ICE 32 treated system.

  Negative numbers indicate that the evaporator has achieved the desired pressure with less compressor activity. The variable drive action neutralizes compressor output, saving horsepower and reducing evaporator capacity.
