Toyota refrigerant filling quantities R134a and 1234yf.
Finding out which refrigerant your vehicle uses is easy with the help of A/C Pro®. The first place to look for this information is under the hood. Pop the hood and look for a label, which is usually white or bright yellow. On this it will either say “R-134a” or “R-1234yf,” and it may even say what the capacity is.
Service new refrigerant vehicles with the Toyota SAE-standard 11815-00008 machine. The 11815-00008 fully meets SAE's requirement for recovering, recycling, and recharging vehicle A/C systems that use the new R1234YF refrigerant.
The air conditioning system on all modern vehicles is charged with R-134a, while some older vehicles still use R-12 freon. The refrigerant changes between a liquid and gas state, absorbing heat from inside the cabin.

Certified A/C Pro R-134a PAG 46 Refrigerant Oil with ICE 32. This product contains approximately 8 fluid ounces of PAG refrigerant oil with ICE32. Low viscosity PAG oil for R-134a auto A/C systems; ISO 46 viscosity.
Lower Global Warming Potential (GWP): 1234yf refrigerant has a significantly lower GWP compared to 134a, making it a more environmentally friendly option.
Back around 1993 the old R12 was replaced by R134. Now R12 is very expensive while the replacement is cheap. I keep cars for a very long time, and when they get old sometimes the A/C system requires service.
An environmentally more benign refrigerant for replacing refrigerant R410A includes a majority portion of refrigerant R32 and a minority portion of refrigerant R134a, the volumetric capacity of the replacement refrigerant permitting it to be used as a near or exact drop-in replacement for refrigerant R410A in terms of ...

R-134a PAG 46 AC Oil Lubricant: with ICE 32 Lubricant Enhancer features advanced chemistry to help extend compressor life and improve cooling capacity.
Still, the answer is an emphatic, “No.” Not only would a retrofit of this type negate the environmental benefits of R-1234yf, but it would also be a violation of Federal Law under Section 203 of the Clean Air Act: “tampering” with a vehicle's emissions control device.
While R-1234yf could be the perfect replacement for R-134a, there is one major challenge with this new technology. The R-1234yf is much more reactive than R-134a.
General Motors began introducing vehicles to the market utilizing this new system in 2013 with full conversion in 2018. Chrysler, Honda, and Subaru models followed in 2017. It is anticipated that by 2025 all vehicles will contain 1234YF.
Most vehicles have a label or sticker under the hood that indicate whether the refrigerant used is R-134a or R-1234yf.
Switching to R1234yf refrigerant is a step towards a greener future, but it comes with higher costs due to advanced equipment, stringent regulations, and specialized training.
R-1234yf systems that control freeze protection by pressure may encounter loss of cooling performance if charged with 100% R-134a. This is due to the requirement of R-134a to have a lower setting of 3.3 psig to achieve freeze protection at 32 F. This may result in a 4-degree F.
R1234yf, or HFO-1234yf, was introduced in response to environmental concerns over the continued use of HFC-134a. This newer refrigerant is a hydrofluoro olefin (HFO). It has a much lower global warming potential (GWP) compared to HFC-134a.
If you use R-22 in the same system as R-410a, the compressor is going to be trying to work two different fluids through the same coils as both refrigerants respond differently to different mechanical situations. As you might imagine, this isn't going to go well for your air conditioner or heat pump.
In December 2022, the EPA unveiled a refrigerant ban that will go into effect between 2025 and 2026 (depending on the industry). The result? R-410A is out, shaking up the HVACR industry, which relies heavily on this refrigerant.
HFC-134a will no longer be allowed in nonroad vehicles as of January 1, 2028. Servicing of existing vehicles using HFC-134a with HFC-134a will not be impacted and will continue to be allowed.
It is anticipated that by 2025 all vehicles will contain 1234YF. Don't fret, however, if your current vehicle requires 134a. Though 134a is not compatible with 1234YF and is expected to be phased out, it is still in production and will continue as long as there is a demand for repair of older vehicles.
Firstly, the primary difference is the environmental impact. Old refrigerants like R-12 and R-134a are known to contribute to ozone depletion and global warming. In contrast, 1234YF is classified as a has a much lower global warming potential. Secondly, the performance of the refrigerants is different.
