HARRISON A-6, 6-Cylinder Compressor Oil Checking: Notes
NOTE:
Harrison Compressors, built by the Harrison Radiator Division of General Motors, may have been referred to in the past as Frigidaire, General Motors or Delco-Air Compressors.
The system is fully charged with 10 ounces of refrigeration oil. It will not normally require addition of oil unless definite oil loss has occurred due to ruptured line, leaking compressor seal, replacement of system component, compressor overhaul, or vehicle collision.
