In case you didn't know this, wd40 works wonders on removing oil stain on your driveway. Last weekend I changed out the oil in my Skag & like a dumbass, I didn't do it in the grass & didn't pay attention & due to the clearance, the oil didn't quite hit the mark completely. I had a big pool of that shit & it was a mess. I've used wd40 on smaller patches in the past & within a few days, all was gone. I re applied the spray a few days ago & still letting it sit. Thats why it looks so dark. You can see how the area already faded, so it shouldn't be really noticeable in due time.....
