Honda/Acura Oil Requirements For A/C Systems With R-1234yf: UPDATE
I-CAR · April 9, 2026 · Honda, Acura
Summary
This article outlines Honda and Acura's requirement to use specific nonconductive POE compressor oil, rather than PAG oil, for A/C systems utilizing R-1234yf refrigerant. It emphasizes that this POE oil is distinct from high-voltage vehicle POE oil and directs technicians to always verify specifications using the OEM's 'A/C Refrigerant and Oil Type Guide'.
What to do on the job
Always reference the Honda/Acura 'A/C Refrigerant and Oil Type Guide' or service manual to identify and use the exact specified POE compressor oil for R-1234yf systems, ensuring not to substitute it with PAG or standard high-voltage POE oils.
How to use it
When writing an estimate or supplement for A/C service on a Honda or Acura vehicle with R-1234yf, include the specific OEM-approved POE compressor oil as a line item. Use this document to defend the charge against insurers who may try to specify standard PAG oil or generic EV POE oil, noting that Honda/Acura explicitly requires a unique, nonconductive POE oil that differs from standard HV oils.
