For coarse finish concrete, just repeatedly grinding clay based kitty litter/oil absorbent with your shoe can do wonders if the oil hasn't soaked too far in. The dust picks up oil and the larger particles abrade the surface to reduce the darkening of the oil. You might need to feather it out if the surface is a special color.
A possibly drastic/overkill option could be to coat the entire driveway with a sealer to darken the entire surface.

At the gas station where I worked we used this stuff, which worked amazingly well- http://enigreen.com/product/create-sweep/
Advertising hyperbole aside, I strongly suspect Crete Sweep was nothing in the world more than portland cement powder in a handy shaker container, but it was easy to use and really did work.

Thanks for all the suggestions. I believe it’s soaked into the concrete too far to do much. The degreaser and power washing made it much better and it’s lightening by the day.. Hardly noticeable now so I think I’ll just live with it.
My friend had his oil seal replaced, btw.
