MAHLE Air conditioning compressor oil "PAG Öl YF"

Universal, for all known air conditioning systems that use the new refrigerant / coolant, except for electric air conditioning compressors
Fully synthetic, hygroscopic oil based on polyalkylene glycol for lubricating and sealing most passenger car and commercial vehicle air conditioning systems. Suitable for R1234yf.

Note from the manufacturer: When using PAG oils, care must be taken to select the correct viscosity class (PAG 46, PAG 100). The specifications and approvals of the vehicle manufacturer must be observed. PAG oils are also hygroscopic. This means that they absorb moisture from the ambient air and bind it to themselves. For this reason, opened oil containers must be resealed immediately and the remaining oil can only be stored for a limited period. This also applies in particular to fresh oil containers on AC service units.
