The 2011 Honda Fit uses R-134a refrigerant (also known as HFC-134a) for its air conditioning system. It is not designed for the newer R-1234yf refrigerant.
This model is part of the second-generation Fit (2009–2014). For service, technicians typically recharge with R-134a refrigerant and use PAG oil specified for this type of system. Do not mix refrigerants, and retrofit to 1234yf without factory-approved guidance.
Refrigerant and lubrication basics
Before servicing the AC, it helps to know the standard refrigerant and oil used by this vehicle and what to avoid.
- Refrigerant: R-134a (HFC-134a)
- Lubricant: PAG oil (usually PAG-46 for R-134a systems)
- Do not use R-1234yf in this vehicle
- Recharge equipment: R-134a refrigerant cans with a compatible gauge set and connectors
- Leak dye: Optional UV dye can be used for leak detection, compatible with R-134a systems
In short, the 2011 Fit’s AC system is designed for R-134a refrigerant with PAG-46 oil. Avoid R-1234yf and follow the vehicle’s service manual or a certified technician’s guidance when servicing the system.
Where to verify the official specification
You can confirm the exact specification by checking the under-hood label near the AC compressor or accumulator, consulting the owner’s manual, or contacting a Honda dealership or certified technician. The label typically lists the refrigerant type (R-134a) and recommended oil information.
Service considerations and safety notes
Refrigerant handling should be performed by a trained technician with EPA certification. Never vent refrigerant to the atmosphere, and ensure proper recovery and charging procedures to protect both the environment and the system.
Summary
The 2011 Honda Fit uses R-134a refrigerant with PAG oil (commonly PAG-46). It is not compatible with R-1234yf. Always verify the spec on the vehicle’s label or service manual, and rely on a certified technician for proper recovery, charging, and leak testing.
