Possibly. I did roughly match the new oil amount to the old. Didn't have a more precise method than by eye, so very possible.

Again, I was without most of my tools or even a decent space to work other than a parking lot before I was kicked out of my housing.
Still, good lessons to be learned thanks to all you helpful folks. I appreciate everyone's input.

Would it be likely the shop technician didn't realise this and somehow overcharged the system?
Like the previous poster mentioned, low pressure wouldn't be likely to cause a burst line.

Yes, I know techs that have made that mistake. To your original question, is your compressor toast, I don't think so. If it still turns freely, then it is probably OK. Charge it back up the right way and stay cool
