It is the natural response of a dry ball rolling on a we surface (lane).  All balls and styles will push oil to some extent.  High porosity balls will absorb some oil and deposit the rest further down the lane.  If you have a ball with a lot of flare, each revolution of the ball is a dry part of the ball rolling through the oil.  It will soak up more oil quicker than a plastic ball rolling through the oil.  When the only types of ball available were polyester balls, then push down was more of a problem than drying up the track.

actually with today's new oils, oil does not push down anymore, Unless plastic is used
every time you roll that ball, it takes oil off the lane
a ball quitting down-lane is actually burned up heads in most cases.

Oil sure carries down where I play. Wood lanes just resurfaced with a heavy 43' ths

While it sure looks like its pushing down, it may not be.
Like avabob says above.
try a ball with less surface(same strength piece if possible) in the same spot after league play is done, you may be surprised at the ball reaction
or if your ball seems to be going to long, trying moving into some more head oil
and use the same target spot downlane.
you r best bet is to experiment after league play is done on the same pair you were just on.
We do that every week with different pieces and surfaces to learn the new ice oil we have in 1 house

Or after league, see if you can actually walk down the lane and see where the pattern ends, there would be oil streaks past the end of the pattern if in fact its pushing down

the house I play in this year decided to start using the cheapest oil on the market

I manage a 32 lane center. Carry-down does happen, but primarily from the house balls and spare balls. Much depends on the volume of oil, and the length of the pattern, too.

One other factor can be is the machine getting a clean strip when it's applying the pattern to the lane?  Not too long ago two of the jets that spray cleaner on to the lane surface were "semi-clogged" and not enough solution was hitting the lane surface to go it's job properly.

Over a couple days the back-ends got progressively weaker, so everyone was asking if we added more volume to the pattern.  We had not, but since the back ends were not squeaky clean the lanes acted more slick (and spotty).

We aren't seeing the heads go, I'm guessing because lane are brand new. But the carry down is terrible come mid to end if game 1.

So even with the new oils and rough surface sponge balls, when the ball comes out of the ball return with oil still visible on the surface of the ball, you are saying NONE of that visible oil is deposited on the lane at the end of the pattern? 

The new oils are truly amazing if that is the case.

nowhere did I say "none"
i am in a Eric Pierson prepared pattern league and there is not much if any carry down by us whatsoever
high fiction HPL lane surface and ice oil
Im sure oil still carries down, but far less than in the past
I can go down the last lane and look where the oil pattern ends, there isnt much oil past the end of the pattern, if any.
Same with a large AMF house, heads go away pretty fast and the balls labors downlane- Bill MOnce runs the proshop there and his thoughts are that the oil is not pushing down, heads burn up, balluses up energy early and has nothing down the lane, which looks alot like carry down
Just my opinion on the places I bowl
