Oils in comparison
Type of oil | Application | Notes |
PAG oils for refrigerant R134a | There are various PAG oils with different flow characteristics (viscosities) for use with refrigerant R134a. PAG oils are hygroscopic. This means that cans do not have a long shelf life once opened. | Standard PAG oils are not suitable for refrigerant R1234yf or for electrically driven air conditioning compressors. |
PAG oil YF for refrigerants R1234yf and R134a | There are also various PAG oils with different flow characteristics (viscosities) for use with refrigerant R1234yf. What makes these PAG oils from the BEHR sales brand special is that they are not only suitable for use with the refrigerant R1234yf but can also be used with the refrigerant R134a. As PAG oils are hygroscopic, cans do not have a long shelf life once opened. | PAG oil YF is suitable for both R1234yf and R134a refrigerants. |
PAG oil SP-A2 for refrigerants R1234yf and R134a | For use in electrically driven air conditioning compressors that have been filled ex works with a special PAG oil. | |
PAO 68 oil for refrigerant R134a, and in some cases for refrigerant R1234yf and others | Can be used as an alternative to the various PAG oils that are offered for R134a (has the advantage of not being hygroscopic—i.e., in contrast to other oils, it does not absorb any moisture from the ambient air). The two different PAO 68 oils offered by MAHLE under the BEHR sales brand (AA1 and AA3) can be used in conjunction with numerous different refrigerants (see product overview). | The AA1 clear version of PAO 68 oil (without leak detecting agent) can also be used with the new refrigerant R1234yf as well as in electrically driven air conditioning compressors in hybrid and electric vehicles. |

* Passenger cars, trucks, and agricultural and construction machinery
** Except for electric air conditioning compressors
The appropriate air conditioning compressor oil is determined on the basis of the air conditioning compressor type and the refrigerant used. The wrong choice can lead to damage.
Vehicle- or manufacturer-specific instructions must be followed carefully.
