I agree that the above degreasers will work very well and it is good to hear of real experience with them especially those cheap ones, but they only work on the surface. Give it a day or so and if the stain was old it will return again. Sure, no oil on the surface however the dark stain will come back up again so my post was a cheap way to get most of it up from below the surface. Also the laundry detergent was a cheap option because the lady of the house usually buys that, but do not get caught! If you spill oil onto the concrete any type of strong detergent or degreaser will work well, but if the oil has been soaking in the hot sun for ages then it will have stained deeper down. In factories under machines that have leaked oil for decades the oil goes all the way through and into the soil. Oil stains are a real pain on concrete and not much gets it out that I have seen, you can only make it better. I used to epoxy paint factory floors, mainly old engineering plants with totally oil soaked floors. I pressure cleaned off the surface muck with my water jet floor mower and recycled the water. After 6,000 psi there was nothing left on the surface, but it was still an oil soaked floor. Then I would flood the floor with a strong detergent and use a ride-on scrubber to agitate it and vacuum pick it up. After two rinses and vacuum pick up we would paint as soon as it dried which took about an hour and it was guaranteed not to peel for life. Tests I did years ago suggested that this system removed everything from perhaps the top 0.5mm only. That was enough for the paint to adhere strongly. If we waited too long it took only 2-3 hrs in summer for the worst stains to appear at the surface again and we would have to spot clean those just before painting. Sorry to bore you, thought it might be interesting to some.
