NAPA and other FLAPS sell thick, absorbent paper sheets for soaking up  oil.
In my driveway, I put down enough sheets to cover the spill and soak  the
sheets with kerosene.  The kerosene helps release the oil from the  cement and it
transfers to the paper. Sometimes another application and  some scrubbing is
necessary, for oil leaks from diesels, for example. The  kerosene eventually
evaporates leaving a fairly clean spot.  Gasoline can  also be used to speed up
the process but it evaporates faster so more  applications are necessary.
