From what i know the FC and FD both run oil pumps to squirt oil from pan into the internals to lube the seals and surface. The main issue is people have questioned the quality of said oils as it is dirty and may carry debris. So what has been done is to remove the oil pump and rum pre-mix. The fc runs a mechanical pump whereas the fd runs a electronic pump.
You can safely run pre-mix even with oil pump. Here it is important to note "more doesnt mean better". I am trying out idemitsu's rotary premix. The instant good part is the fact the bottle comes pre-marked which is stark contrast to the shell 2t bottles.
