Oil trap or double riser.

Depends on the system. I had systems where the liquid is so "dry", we need to inject oil in the liquid line to let solenoids and electronic expansion valves operating freely. On screw systems

3/8" oil line on solenoid valve, 3 seconds on, 20 minutes off.

No sense for humor, or simple nerds?

Not if you drain all the oil out first.
