Worked Great for Me!
Works Great! This product does take 4-6 weeks depending on your oil stain. I had a small drip that went completely away after 2 applications. I also have a giant oil stain that a leaky car parked on for over a year.  I am now on week four and the stain is almost completely gone.  Even though it takes time for the product to do it's magic, the color of it blends better with asphalt than a giant oil stain.
