Hi guys, just checking, do I need to flush the semi synthetic oil out if I'm adding mineral? This is a full oil change

No. Just drain as normal, ideally with engine warm. Any thats left will make no odds.

it may take a little while for the oil in tappets to change from semi synth to mineral.

if you are changing because of noisy tappets be patient.
