R-1234yf is not miscible with any refrigerant oils.

Explanation:
Oil-refrigerant miscibility depends on the type of oil. R-1234yf is designed to work with polyol ester (POE) lubricants, and it mixes with POE oils in typical A/C systems. That means the claim “not miscible with any refrigerant oils” isn’t true, because there are oils it does mix with. In contrast, mineral oil isn’t compatible with R-1234yf, which is why POE is the recommended oil for this refrigerant. So the statement is incorrect, since R-1234yf can be miscible with certain refrigerant oils (like POE) even though it’s not compatible with mineral oil.
