How do you remove oil stain from asphalt surface?

Question

Its in a carport.

Answer 1

Instructions
STEP 1: Spread a thick layer of fresh sawdust or kitty litter over the grease to absorb excess grease or oil on the surface. STEP 2: Allow the sawdust or kitty litter to sit for a day or two. STEP 3: Gently sweep away the dirty sawdust or kitty litter. STEP 4: Pour dry cement over the entire dried grease spot. STEP 5: Allow the cement to sit for a day or two. STEP 6: Gently sweep away the dirty cement. STEP 7: Gather dirty cement in a bag and throw it away. Do not allow the dirty dry cement to go down the sewer. Tips & Warnings
The kitty litter and sawdust soak up grease on the surface, whereas the dry cement actually absorbs the stain out of the driveway.
For best results, clean up grease stains as soon as they happen.
Avoid further staining by using large automotive drip pans for vehicles that leak.
Make sure the forecast is clear for the days you'll be using dry cement on the grease spots if they are outdoors. Dry cement and water will create hardened concrete.

Answer 2

Throw some cat litter on it. That helps draw it out of the asphalt. Or, check an auto aisle in a store, there is actually special stuff like Oil B Gone or something like that, which is really more expensive kitty litter.

Answer 3

Don't know how long this stain has been down there but oil &
gasoline will soften or eat asphault.
Best bet is to use "kitty-liter",cheapest stuff you can find.It's all
the same stuff.Dryed clay.Same-same with oil absorbing prod-ucts.
I don't know of any way of removing a stain other than to dig it out &
patching.
