How much PAG oil do I need?
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.
What fluid 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.
Is PAG 46 and PAG 100 Compatible?
➔ 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.
How much oil does a Denso compressor take?
The total amount of oil in the new compressor (A) is 120 cm³. The oil amount drained from the old compressor (B) is 50 cm³. The amount of oil to remove (C) from the new compressor is A-B, 120-50= 70 cm³.

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.
How much oil does a car AC compressor need?
A/C Compressor Oil Capacities The total system oil capacity for many late model passenger car A/C systems is only about 4 ounces (120 ml). A low oil level can starve the compressor for oil and lead to compressor failure. CAUTION: Do NOT overfill the the A/C system with too much compressor oil.
How much oil do I put in my compressor?
Oil should be filled until the sight glass is 1/2 to 2/3 full on all models.
Should I 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.
