Simple Green and a power washer might lift them?
Is there a product to get rid of oil stains on concrete? The parking spot I have has a ton of oil stains from whoever lived there before and that just really gets to me. anything I can "wash" the concrete with?
Lots of concrete etching compounds that you use before you put down epoxy, Try this stuff maybe http://www.seal-krete.com/osr.htm

Lestoil - the stuff works great. 2nd place for me would be simple green.
What actually works friggin awesome is the material inside sheetrock. Someone had recommended it to me and I tried it with an old piece I had lying around. It lifts the oldest oil stains really well.

There's a special heat gun that's made for this. I've seen pavers use it and I know I saw one for sale at Home Depot in the past.
When you heat up the tarmac, the oil rises to the surface. That's when you throw down your Speedy Dry or other absorbant material.
It's going to be the same outcome.
IF it gets rain....
kerosene will move lots of it relatively safely
Then dawn about 50/50 with water spay let soak in or srub with very stiff brush
do it a day before a big rain storm ...SSSHHH!
You might finish the tough ones with carb cleaner spray and bloking
