Customers ask us all the time; "what is the correct amount of U-Gauge oil"?  Fact is, there really is no specific amount.  When a neon unit is filled to 20mm of gas pressure, you want to have enough oil in the U-Gauge so that the oil is not pushed past the bottom of the U-Gauge "U" bend. If the oil were to go past this "U" bend, air or gas will enter the other side of the "U".  If this does happen, don't panic, nothing will be damaged. The problem created by the air or gas entering the other side of the "U", would be the U-Gauge reading will be off, or at least until the oil has time to resettle.
