OK this isn't really Land Rover related (as my Land Rover doesn't leak! crossing fingers), however my daily driver does leak oil. At my current house it's not a big deal as I park in the street and the street gets the mess. I am moving into a new place with a nice, clean driveway and I really don't want to put a big ugly oil stain in the middle of it. Any ideas for something I could put down on the driveway?
