Multiple Choice

AB oil is miscible in HCFC blends.

Explanation:
Oil circulation and lubrication in refrigerant systems depend on whether the lubricant mixes with the refrigerant. AB oil is formulated to be miscible with HCFC blends, so it dissolves into the refrigerant rather than remaining separate. This allows the oil to travel with the refrigerant through the system, ensuring that lubrication reaches the compressor and that oil is returned properly instead of forming separate pockets. In HCFC-based systems, using a lubricant that mixes with the refrigerant helps prevent oil traps, varnish buildup, and inadequate lubrication. Because AB oil is compatible with HCFC blends, its miscibility is expected and beneficial.
