What kind of oil is AC compressor oil?

PAG is actually an acronym for Polyalkylene Glycol, and it is a synthetic oil used in A/C systems to lubricate the compressor. Most all newer model cars use PAG as the lubricant in the A/C system. When people refer to PAG oil they typically refer to it in the following terms: PAG 46, PAG 100, or PAG 150.

What lubricant can be used in an air conditioning systems?

CFC-12 auto ac systems, for example, use mineral oil lubricant products. Most HFC-134a systems use a synthetic lubricants called polyalkylene glycol (PAGs) or polyol esters (POEs). The shift to PAGs and POEs occurred because mineral oils were not suitable for use with HFC refrigerants such as R-134a .

What can I use instead of compressor oil?

Substitutes for Air Compressor Oils

• Hydraulic oil: Hydraulic oil possesses multiple qualities that make it an acceptable substitute for air compressor oils.
• Automatic transmission fluid: Automatic transmission fluid (ATF) is primarily used in car transmissions, but some kinds can also be used in air compressors.

Can I use PAG 46 instead of pag100?

➔ PAG oils are highly miscible with R134a (PAG oils 46 YF and 100 YF also with R1234yf) and are suitable for lubricating the air conditioning systems of most passenger and commercial vehicles.

What is the difference between mineral oil and POE oil?

Mineral – a by-product in the distillation of crude oil to produce gasoline. Polyolester (POE) – the primarily synthetic oil for refrigeration systems using HFC refrigerants. It is also suitable for refrigeration systems using CFC, HCFC refrigerants and being evaluated in CO2 systems.

How do I lubricate my AC compressor?

Pour the oil very slowly into the intake port or low side of the compressor. This is where the large line entered. While pouring in the refrigerant oil, rotate the hub and clutch slowly to let the oil enter the compressor.

Can I use ATF as compressor oil?

ATF Oil. Automatic Transmission Fluid oil is another one that we see being used in compressors. While most ATF fluids have some detergents in them, they are designed to go long distances without being changed. This makes them better suited for use in compressors.

What happens if you mix PAG oils?

They should not be mixed with mineral oils. The result is a gelatinous, gooey mess. Although they are excellent lubricants, they can pose a logistic problem in plants. They can also have some negative effects on paints and seals, and are very expensive.

What happens if I use the wrong PAG oil?

Using the wrong oil may allow current to short circuit back through the A/C compressor, creating a shock hazard. Mineral oil should only be used in older R-12 A/C compressors because R-12 will not mix with R-134 refrigerant. This can lead to poor lubrication and premature compressor failure.
