I really did not know how much oil to add. I didn't have a particlar oil leak, my AC guy said it might need a small amount but not an entire 7.6 ounce ill. And really the only way to be sure is to drain it all out, flush the lines and start from fresh. . So added a small charge, and hope it's close enough.
I'm reading the high side off the Gap and the low side was done at the fill hose. Basically added R134 until it got into the green zone, and was still at the low side of it. His guage set is for commercial and residential AC and didn't have the adapter for the R134 cans so it didn't get used-would have been better. It's blowing cold and that's pretty darn nice, Admittedly its a half assed fix but I'm not sure if I am committed to a major system redo.
