True or False: The statement 'R1234yf is not miscible in any refrigerant oils' is true.

Explanation:
R1234yf’s miscibility depends on the oil used. It does not mix with mineral oil, but it does mix with polyol ester (POE) oils that are typical refrigerant lubricants for R1234yf systems. Saying it is not miscible in any refrigerant oils uses an absolute, which isn’t correct. In practice, R1234yf systems are paired with POE oil to form a single phase, providing proper lubrication. Mineral oil systems, in contrast, do not achieve miscibility with R1234yf.
