What oil do you use with R134a?

PAG oil: Polyalkylene Glycol or PAG oil is a man-made lubricant used in both R134a systems and the latest R1234yf. There are several types of PAG oil based on the viscosity of the oil -- PAG46, PAG100 and PAG150 -- and the type of refrigerant it is designed for.

What type of oil do you use with R134a?

Polyolester oil is a type of synthetic oil that is compatible with the R-134a, R-410A and R-12 refrigerants. Experts say it is a good substitute for hydrofluorocarbons.

Does R134a use mineral oil?

R12 systems used mineral oil, but unfortunately mineral oil doesn't dissolve in R134a. 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).

What type of PAG oil should I use?

➔ 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. ➔ The choice of the right viscosity is crucial when using PAG oils (PAG 46, PAG 100, PAG 150).

What type of refrigerant oil should be used on the O ring seals with a 134a system?

Mineral oil: Mineral refrigerant oil, also known as Alkyl Benzene Oil, was the default option up until HFC refrigerants became common place. Today it is still used in older R-12 refrigerant systems. And because it does not absorb moisture, it is also used to lubricate O-rings and seals in both R-12 and R134a systems.

How To Add PAG Oil Into An AC System

Why should you always use mineral oil instead of PAG oil?

PAG oils are harsher than mineral oils, and may cause skin irritation and damage O-rings and seals.

Is pag 46 the same as ND oil 8?

DENSO uses ND-oil 8 for its R134a type refrigerant compressors, a PAG 46 oil. The new refrigerant type uses ND-oil 12, also a PAG 46 oil but with additives specifically for the R1234yf type refrigerant.

Does r134 have PAG oil in it?

PAG oil: Polyalkylene Glycol or PAG oil is a man-made lubricant used in both R134a systems and the latest R1234yf.

What oil is best for compressor?

For compressor oil, you want to use either SAE 20 or SAE 30 oil, where the latter is the more viscous of the two. If you live in a cold region, then it is better to go for SAE 20 compressor oil. Those who live in warmer places should use SAE 30. This is based on how the viscosity may change depending on the weather.

What is PAG 46 oil used for?

Fully synthetic, polyalkylene glycol (PAG)-based oil which is used for the lubrication, sealing and cooling of refrigerant compressors or refrigerant circuits in passenger or commercial vehicle air conditioning systems.

Do I need to add oil when recharging AC?

The best way to ensure the long life of your AC compressor is to ensure that you add adequate oil any time you add refrigerant to your system. If you've discovered a need for more refrigerant in your vehicle, add BlueDevil Red Angel One Shot.

Is ester oil the same as mineral oil?

Esters, natural and synthetic, have higher temperature stability than mineral oil, meaning esters can be exposed to a higher temperature for longer periods with less degradation than would be expected when using mineral oil.

What type oil goes in AC compressor?

The two categories of oils commonly used in the compressors are mineral or synthetic oils. One type of mineral oil (MO) called Naphthenic is commonly used. Synthetic oils such as glycols, esters and alkylbenzenes (AB) have been used in the refrigeration applications for some time without any problem.

What is PAG 150 oil used for?

Compressor Oil PAG 150 is specially developed for mobile airconditioning units, which use the refrigerant R134a. Compressor oil PAG 150 has due the high Viscosity Index (VI) a wide temperature operating window and can be used for a wide range of vehicles.

What are ester oils?

Ester oil is synthetic base oil that has been chemically synthesized. Typically ester oils are used in passenger car air-conditioning compressors, refrigerators and other industrial applications. Esters are one of the classes of synthetics that have been used in Mobil 1™ oils as well.

What is the difference between Poe and Pag oil?

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. ​​Polyalkylene​ Glycol (PAG) – a synthetic oil primarily used in R-134a automotive air conditioning systems.

Can I use SAE 30 oil in my air compressor?

The Clear Choice for Lubricated Compressors

In general, manufacturers today recommend using either a 20 or 30 weight synthetic lubricant — rather than a mineral oil — to get the best results out of your industrial compressed air system.

Can I use 10W30 in my air compressor?

Can you use 10W30 in your air compressor? No. The recommendation by manufacturers of air compressors and the advice of air compressor experts is to use air compressor oils without detergents. Since 10W30 contains detergents, it should not be used.

Can I use engine oil in my air compressor?

Yes, you can use motor oil in your air compressor. It is the motor oil's job to work well with different parts of an engine to handle high temperatures and low temperatures.

Can you mix synthetic R134a with non synthetic?

A: No can do. The system will have to be evacuated properly, to remove any oil and any water or humidity that got in. Then you can add the correct amount of oil and refrigerant, in this case R134a.

Can you mix refrigerant oils?

When using CFC or HCHC refrigerants, POE and MO can be mixed. The exception is R12 that only uses MO or Alkyl Benzene Mineral Oil (ABMO) blend. HFC refrigerants can only use POE oil.

How much PAG oil do I put in a compressor?

Does R134a deteriorate?

No. Your car's A/C refrigerant never goes bad. Nor do you “use up” the refrigerant that is in your system. If your vehicle's A/C system pressure is low, your vehicle has a refrigerant leak and that leak will need to be repaired in order for your system to hold refrigerant.
