While they can be unsightly and difficult to remove, by using certain methods you can get oil out of your concrete. In many cases, stains can be removed completely to restore the area to its former clean appearance. Here are some methods for how to remove oil stains from concrete.

Using a medium- to heavy-duty pressure washer can remove or lighten oil stains on your concrete driveway if the spill is relatively new. First, apply a commercial-grade cleaner to the oil stain and scrub with a brush or broom. Then add detergent to your pressure washer and begin spraying.
Oil will break down the sealant/finish on the top layer and seep into the tiny pores of the concrete, creating a permanent stain, if not taken care of. It's best to take care of even a minor stain, right away!
In some cases, WD-40 can remove oil stains from concrete. However, it isn't as effective as other methods and depends on how old the stain is. If you have it on hand, you can try it by spraying it on the stain and letting it sit for 30 minutes. Scrub it with your brush, then soak it up with the cat litter.
The most common oil remover is the degreaser, Simple Green. While Simple Green is most effective at removing fresh oil stains from concrete, it's gentle on outdoor concrete, and you can easily apply it to large areas. Further, it's inexpensive, and you can buy it at any hardware or auto parts store.
Instead of a brightly colored stain, oil leaves a greasy patch behind that's slightly darker than the surrounding fabric.

Pour baking soda over the entire stain and let it sit for about an hour – the longer the better, particularly with old grease stains. Next, add liquid dishwasher detergent to the baking soda. Use a stiff nylon scrub brush to work the dish soap in. Scrub at the stain until you are sure that it is gone.
Oil-based stain can be kept for 1 year if the cans have been opened, but unopened cans will last 2 - 3 yrs. Water-based stain will last 1 year, if opened, and 2 years, if unopened. Oil-based varnishes will be good for 1 year, opened or unopened.
Coke is also a wonderful tool for removing old motor oil stains. First, pour a can of Coke over the stained area, then leave it overnight, allowing Coke's high acidity time to gradually eat away at the stain.

There's a good chance that small, relatively new oil stains can be removed with hot water, detergent and a steel brush. Simply apply the detergent and scrub with a steel brush, clean with water then repeat if necessary.
Another way to remove oil stains from concrete is a poultice, especially for small, stubborn stains.
