So I'm a marketer for GoG exclusively selling the eNMEy's and have also been a solid owner of the eNMEy since it came out. From what I found with most markers, including the eNMEy, that it's normally a GOOD idea to wipe off the factory lube not because it's bad or anything, but because you dont know how long that lube has been in there, and it's nice to know that you have a fresh batch of lube in your marker.
GoG recommends GR33SE, or Sl33k lubricant for your markers. It's Dow33, so if you cant get those, then your next best bet is any other Dow 33 based lube. I have also found Lurker Lube to be also pretty good as well, especially since it is clear. It's not dow33, but it has the sleekness and consistency of it, and is made to work on markers.
