My first suggestion would be painters naptha and kitty litter. Pour the naptha on the stains and allow it to soak in. Then pour some more on, then cover it with kitty litter. This process draws the oil from the concrete into the litter over a period of time. Repeat as necessary. If solvent cannot be used (pilot lights, attached garage) see the doityourself.com how to pages for suggestions on cleaning concrete and poultices for. Mobile hot water powerwashing or steam cleaning services can help you also.

Preparing previously unpainted concrete: http://bbs.doityourself.com/ubb/Forum12/HTML/000121.html Concrete floor paint works well.
