What weight PAG oil should I use?
There are different viscosities of PAG oil being used by OEMs: PAG 46, which is the most popular; PAG 100, which is also common; and PAG 150, which is more rarely used.
What happens if I use the wrong PAG oil?
The use of low-quality or even the wrong oil – just like with the engine – leads to increased wear, premature compressor failure, and loss of warranty/guarantee. Note: Using the wrong oil can cause damage. ➔ The choice of the right viscosity is crucial when using PAG oils (PAG 46, PAG 100, PAG 150).
Can you mix PAG and mineral oil?
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 refrigerant is compatible with mineral oil?
Naphthene based mineral oils are suitable for refrigeration systems using CFC or HCFC refrigerants.
What viscosity is Pag 46?
Typical properties
| Performance attribute | 46 | 100 |
|---|---|---|
| Viscosity @ 40°C (cSt) | 44 | 95 |
| Viscosity @ 100°C (cSt) | 6,8 | 11,8 |
| Viscosity Index | 108 | 114 |
| Pour Point (°C) (cSt) | -48 | -40 |
Is PAG 46 Synthetic?
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.
Does Poe oil absorb moisture?
All POE oils are highly hydroscopic; they absorb moisture quickly and hold the moisture they absorb. Once absorbed, the moisture cannot be removed through system evacuation even at a vacuum pressure as low as 500 microns (millitorr).
How much refrigerant oil should I add?
The AC system requires a Usually of 4 ounces (120 ml) of oil in most modern automobiles. So it is a good idea to test the manual to be sure of the exact amount and to prevent over- or under-filling of the system. Low oil levels can cause compression failure and overfill often hurts the efficiency of the cooling cycle.
Is R134a compatible with mineral oil?
R134a and mineral oils are not miscible. 3. Polyol ester oils and R134a are miscible.
What oil does r404a use?
R-404A is a HFC and Polyol Ester is the only approved oil. The Alkyl Benzene will not be miscible with the HFC. The HCFC refrigerants have a small amount of chlorine that is miscible with the AB oil.
Can you use mineral oil with 404A?
Mineral Oil: Mineral oil has been the lubricant of choice for systems utilizing many of the CFC and HCFC refrigerants. Both the CFCs and HCFCs tend to have adequate miscibility with mineral oil, helping to ensure acceptable oil return under normal operating conditions.
What kind of oil do you use with 404A?
