Did you notice the A/C refrigerant that is in the 2016 Honda Civic? It's R-1234yf and it’s no typo that Honda is requiring POE compressor oil for this system and not PAG (like other OEMs).

According to Honda/Acuar, POE oil is used because it's nonconductive. The 2016 Pilot, Civic, and Fit EV are using R-1234yf. As new models are redesigned or introduced, they will have R-1234yf with POE oil. The POE oil that is required for these systems on Honda/Acura vehicles is not the same oil that is required for high-voltage vehicles (HV).

The A/C Refrigerant And Oil Type Guide document provides vehicle-specific refrigerant oil requirements. To locate the document after logging into the service site:

  1. Click Service Information (top of webpage)
  2. Select Model from dropdown (left side of webpage)
  3. Select Year from dropdown
  4. Type A/C in Type-In Keyword box (top left of webpage)
  5. Click Search
  6. Click blue text for A/C Refrigerant And Oil Guide (center of webpage)

Per the 2025 Honda Accord Hybrid A/C Refrigerant Oil Replacement procedure: "NOTE: Although the refrigerant oil information is listed on the under-hood air conditioning information label, always use the recommended refrigerant oil listed in this service manual or "A/C Refrigerant and Oil Type Guide"."

This change in refrigerant is also due to the EPA announcement in July 2015 that R-134a will be banned in new vehicles for use in the U.S. as of the 2021 model year.
