I bought an old Mercedes diesel recently only to have it leak fuel on
my relatively new asphalt driveway. It is about a 2 foot x 4 foot
spill area. The asphalt here has softened up. What's the best way to
deal with it? Patch over with more asphalt? Allow the diesel to
evaporate (???) and then patch? I'm not sure if driveway sealant would
help.

Thanks for any suggestions,

Chuck
