Use an oil-sweep product. Typically, these look similar to kitty-litter.
In California, we get "rice hull ash". Basically, the leftovers
from rice production. Spread generously on the affected area, and
rub in with the back edge of a push broom. Wait, remove, repeat.
I usually leave it on at least a day. It will 'suck' a good portion
of the oil out of the concrete.

If it's got more than a sprinkling of oil, you probably can't.
Concrete surface prep for painting or other treatments involve cleaning
real well with water, then you etch the surface with muratic acid.
