I never serviced my MKS pedals (4 sets now) on arrival and I've had many happy miles of pedaling adventure.
Not saying a good greasing won't fix most issues, but it's a misnomer to say you need to do it to new ones.

This is Africa, 1943. War spits out its violence overhead and the sandy graveyard swallows it up. Her name is King Nine, B-25, medium bomber, Twelfth Air Force. On a hot, still morning she took off from Tunisia to bomb the southern tip of Italy. An errant piece of flak tore a hole in a wing tank and, like a wounded bird, this is where she landed, not to return on this day, or any other day.
