Hi All
i have a system charged with 3 Ltr PVE oil , i have to add 2 Ltr oil because of leakage so can i mix POE Oil in PVE Oil ? what will be the impact

It seems that 10% of a PVE charge can be of POE.

With your loss I would suggest removing the remains of the existing oil charge and install a complete POE charge, make sure that you have filter/driers installed as POE sucks in moisture whoie PVE doesn't.

Its like oil and water, they don't mix.
