With the jack sitting LEVEL with it all the way compressed (down) the oil should be level with the hole.. Sometimes temp. can cause the level to seem alittle off.. An .oz or so of oil isnt anything to worry about.. When you do refill it, fill- Raise to MAx and lower--- Check again--- If low repeat Procedure.
At least thats how I service all my jacks
