In secrecy they have been modifying some componenets to increase the oil return. They have added small drain holes to the fluid/gas separator to allow fluid to seep through slowly. Some oil collects in the separator and the drain holes would increase oil return.
Thing is, you never know which separator your particular unit is equipped with...
Adding oil helps. It makes sure the compressor can operate longer in "oil starvation mode" I.E. times when the outside evap is covered in frost and it is still some long time until defrost.
During manual water spray-on tests the evap temps dropped to -30 something in 25 minutes!
At those low temps the "68"-classed oil becomes more like wax in consistency.
So normally, oil would return slowly once the separator is filled up to the drain holes level. However, with the outside evap being 10-30 below freezing the oil begins to thicken considerably and sticks inside evap.
There is more about this in this forum "H16" part of Panasonic. The original H16 thread is about 1100 posts long!
Easiest is to study the "Oljeinjektering" thread.
