How do I refill r134a refrigerant?

[Sanu83]

My car (BMW X3 2008) was not blowing very cool air. So, I bought the below stuff and tried refilling with the blue hose connecting to the lower valve but the gauge showed 60PSI.
From the chart I have seen, it should not exceed more than 35psi, if the outside temperature is around 23 degrees celsius/ 73 degrees Farenheit. So, I kind of freaked out and stopped refilling immediately. It was right when I started. So, I didn't even fill anything.
1. Is 60PSI ok?
2. How do I refill anyway?

3. Also, I bought this stop leak oil but I dont have any instructions on the can. How do I fill this?

You need to go to a real shop which has proper a/c servicing equipment. TWO gauges are needed to ascertain what the situation is, not just one on the low side.

Engine and compressor running while getting your pressure reading?
High pressure on low side could be a number of things including already being overcharged. Continuing to fill an already overcharged system can result in the compressor being damaged. If the compressor sees liquid refrigerant things get ugly fast.
