What happens when compressor has too much oil?
Too much oil in the compressor can also cause oil trips. Excessive oil can cause enough turbulence in the crankcase to result in low net oil pressure. In another twist of too much oil in the sight glass, the high level of oil may be caused by liquid refrigerant in the crankcase.What happens if not enough oil in AC compressor?
Without enough oil in the crankcase to properly lubricate the load-bearing surfaces, wearing and scoring happen. There just isn't enough refrigerant mass flow in the system to return oil to the compressor as fast as it is pumped out. Without enough oil, those surfaces become visibly scored or worn.Can low oil cause AC to stop working?
Inadequate oil lubricant. To take the heart comparison a step further, think of your air conditioner's oil lubricant like the blood in your body.

Refrigerant or PAG (synthetic compressor) oil is clear, he explains. Over time, it picks up moisture and turns acidic, eating away at the condenser, thermal expansion valve, evaporator, fittings, compressor and other metal components.

So, along with R134a came a new oil: Polyalkylene Glycol—or PAG oil. Note that there is another kind of oil called Polyol Ester Oil (POE). The advantage of ester oil is that it works with both R12 as well as R134a, so you can fill the system with it and then use either refrigerant.What kills an AC compressor?
Excessive Refrigerant ChargeEither way, an overcharged system may end up destroying your compressor through the phenomenon known as liquid slugging. Liquid slugging refers to the penetration of liquid refrigerant into moving parts of the compressor where only gaseous refrigerant was meant to go.
How much oil does a 60 gallon air compressor take?
Horsepower (HP) 3.2 Tank Outlet Size 3/4 NPT Number of Cylinders 2 Oil Capacity approximately 8.5 ounces Voltage 230 / 240 Volts, 15 Amps Length 20 in. 60 Hz, 1 Phase Width 20 in.Which oil is used in AC compressor?
