    OP here So I tried 2 times to get my car looked at but everything is so busy the best they could offer was to leave it and they might get to it in a few hours…..I’m too busy to give up my car and bum rides that much. I often have to drive to another plant across town with no warning. So the ambient temp was 75F and I knew that was a sweet spot. So I decided to do it myself for the convenience. YES, I wanted to go to a pro as recommended but …LIFE. Ambient 76F. Vent temp on MAX AC is 60F. AC fan on low is 44F. Low side read 32psi with “AC PRO” nozzle – hey better than nothing. I don’t have gauges for High side L. Really not bad. Online chart says it should be 40-45psi low side. Added a 3oz bottle of PAG46 (actually 1oz 46, 1 oz mystery crap, 1 oz R134a). Since I soaked up the spilled oil with a few paper towels I figure this is plenty of oil. I estimate 1 oz after refilling the pan from a kitchen measuring cup of water to the same level as the oil lost. Then added part of a 12oz can of R134a but never could get the pressure to over 40psi. Also not sure how much went in as I later dumped the rest of that can in a Buick. Final result: Ambient 76F. Vent temp on MAX AC is 56F. AC fan on low is 41F. Low side read 39-40psi. 4F drop in MAC AC vent temp and 3F drop in AC temp on low fan. Time will tell if I estimated the amount of oil properly.
