Re: amount of freon
one rule of thumb is:
ambient temp (air temp in front of radiator/condeser) x 2 = min high pressure reading
ambient temp x 2 + 50 = max high pressure reading.
example:
ambient air temp = 70 degrees
x 2 = 140 = min high pressure reading
140 + 50 = 190 max high pressure reading
The oil should be about the same as the spec.
