fluids in your driveway

[Blitzkrieg Bob]

for concrete

TSP = trisodium phosphate
or

Muratic acid for bad stains

for asphalt black top = for a fresh spill, put concrete mix (just the powder to soak and bind the oil) periodcally reseal with black pitch. (oils deatroy black top and reduce it to gravel)

I use cat litter (the clay type) and work it into the spill and sweep it away. Works great.

For concrete I have used lighter fluid, like for your Zippo. Just spilled it on wait a little while, brush it around and hose off. It removed VERY bad stains.
