Hi everyone,

A few months ago, my car had a major oil leak ( Rear Main Seal ), and
when I started it up, oil basically POURED right out in A STREAM, and my
car went through one quart of oil in like 5 minutes. There was a HUGE
puddle of oil all over the driveway. I used kitty litter to try to soak
it all up. and then tried to wash it away with some "Dawn Dish Soap".

Anyway, now everytime it rains, the driveway gets puddles of that
"rainbow colored" oily water. When I try to wash it with the "Dawn Dish
Soap", the white foamy bubbles from the Dish Soap turn all Black. So the
bubbles all turn this foamy Black color, and the water underneath is all
rainbow colored.

So the other day, what I noticed after the snow melted on the grassy
area next to the driveway, was that there was an area about 3-4 feet
long, and about 1 foot wide, where the grass has turned all Black, and
the soil is now a GRAY color. The reason for this, is because the
asphalt driveway is very old, and not perfectly flat, and so the water
and melting snow runs down onto the grass and soil.

So does this mean that the soil is now contaminated with oil? Do I have
to dig out all the grey-colored soil, and reseed the whole area? If so,
how far down do I need to dig?

Instead of digging all the soil out, can I fix the soil, by just
topdressing the gray soil with some compost or organic topsoil, and then
reseed?

Because its not like the motor oil was dumped or spilled directly on the
grass, but the oily residue in the driveway mixed in with rainwater and
melting snow, and turned the grass Black, and the soil a greasy/oily
grey color.

Any suggestions would greatly be appreciated!!!

P.S.
Is there anyway to DRY OUT the oily residue in the driveway, so that
when it rains, the puddles won't have that oily, rainbow color? Will
scattering "rock salt" down on the area where the oil spill was, help to
dry it out? Because doesn't rock salt dry stuff out?

First scrub hard some liquid or powder Tide of other washing powder
into the surface wherever you think the oil residue is located. Then
grind in some kitty litter and let it sit for a day. Then, when the
temp is above freezing, wash the whole area down toward the street,
use the hose to redirect any water that goes toward the grass to the
middle of the driveway and then down to the curb/gutter.

I have had to do this a few times when visitors stayed overnight and
parked their dripping vehicles in my driveway. You may have to repeat
this a few times, The oily film can be caused by a very tiny amount
of oil so don't be discouraged if you have to repeat. Instead of
kitty litter, you can use some regular dirt from around your house if
you have a high spot you want to level out.
