  They're both.  The big difference is in the second ring.  If you're
with a three piece oil ring then you know what the two "rails" are like.  A
thin ring.  The second ring is partly cut, from the bottom, to hold a ring
that looks like an oil rail.  A small part of the original ring is left, full
width, on the inside.  The rest is cut away about 1/16 of an inch up.
The small ring snaps in place in that grove with the gap 180 degrees
from the larger gap.  This cuts blowby to nil, even in a TD.  They also
claim to have much less cylinder pressure since it's not needed to
prevent blowby.  This results in better power, mileage and longer
engine life.

  You have to have the engine out to do it and it's a darn good idea.  There
are two of them and they go in and out like a V-8 cam bearing.  Some
need to be honed to size after installed.  This is a major pain to do without
the tools!  It's something to consider letting a shop do.  :)
