That’s right. Two days later the customer called and said it was cooling terrible. I had him bring it back in and put the gauges on it and checked the vent temperature and it was running about 325 on the high side and about 45 on the low side and the vent temperature was about 55 as I indicated earlier.  Of course, it was in the low 90’s that day.

If you are installing an OEM replacement compressor in this example then it “should” contain 4.5 ounces of oil but if the compressor is not drained and the oil measured, the amount will not be known for sure.  Also, if an aftermarket compressor is being installed, there is no standard that exists in the industry regarding the amount of oil that might be shipped in a replacement compressor.  It might have no oil in it, a partial charge, or a full charge or even more than a full charge. To make matters worse, the OEM does not provide the total system capacity for this vehicle.
