Did I mess up? I've replaced the compressor, receiver/dryer and expansion valve. The compressor came with oil in it, unsure of how much and the distributor said I should probably add more oil to the system. My mechanic also said I should add about an ounce considering I replaced the dryer.
The pressurized can I got from the part store was supposed to be 2 ounces so I figured I give it a shot then cap it off before it all went in. Unfortunately that didn't happen, the whole can immediately discharged into the system, probably because it was the first thing I added and the system was still holding a vacuum. A closer look revealed the can held 3 ounces!
So anyway, I decide probably no harm done and added the Duracool. Based on advice reported here, I believed it would take 2 full cans and a part of the third. The consensus is add until you get to 30-35 psi on the suction side. After two cans, I'm at 42 psi! Cooling at idle seems okay but is it going to be too much when I'm traveling down the road? Did the extra oil...if there is in fact, extra, cause a problem? Where to go from here?
