Not personally. Spendy? How much is an hour of his time worth?
I always start with the most promising solution first, playing Guinea pig is too expensive for me.
A bottle of Dawn is a lot less than $100. Spendy.

He already has several man hours of time in it.

He's probably looking for proven methods.
The reason I asked if you had used it is because, since you haven't, it is the guinea pig. Just a more expensive one. Never heard of such a product before, so there's a fair chance it may not work.

Have you used Dawn to clean hydraulic fluid from asphalt? :D
My point is nobody here has said they used either successfully, but the one company claims they do, while Dawn doesn't. Yes I would give it a try.

Edit: Not that there's anything wrong with Dawn. I would try that too if I had it handy.

How big of a stain?
I cleaned up a pretty big one today size of a dinner plate. I believe I got it but I will know more later. Can’t tell because the driveway was too wet from water.

Remaining big one is watermelon sized, black mottled area about five inches across in the center and the outside donut area is brown. It’s also the most noticeable. There were smaller orange sized stains but they cleaned up okay.

Actually I’m not even sure the big remaining one is from hydraulic oil. I had a rented hoopdie dump truck parked there for weeks. I think it is diesel engine oil.

Thanks for the suggestions everyone.

I've successfully used Dawn to clean asphalt and concrete.

Use Dawn as a emulsent.
Use oil dry to absorb what is "lifted".
Broom/scrub the oildry into the surface; add about 1/2" oill dry to cover;
scuff the oildry into the surface again.

Walk away, let nature work for a few days.
Sweep/vacuum the oil dry to view results. Most often, one application will do the job for light spills.
Mix Dawn with water, kerosene, mineral spirits, or other diluents.
Examples: explanations

Emusions

What did you successfully use for the clean up?

$3 bottle of dish soap, I believe it was Dawn but coulda been Palm. I was standing there for a long time deciding lol.

Too early to tell how successful I was, mind.
 
Spray the rest of the driveway with hydraulic oil. Joking, kind of.
I was going to say that. Spray the rest and clean it up. Now it'll all be stained.

There is a small complication to seal coating. The driveway is shared by the neighboring condo owner. Not shared in that they both use the same areas but shared as in contiguous.

Anyway I’ll likely be doing the same job at her house so maybe I can convince everyone it makes sense to wait until I’ve spilled all kinds of stuff on her driveway first before we sealcoat 😂
 
It's the only way.💥💥💥

Welp, stopped by to get the rest of my stuff. Soap and water and scrubbing did nothing for the stains. Just bite the bullet and seal the driveway lol. @Robie go ahead say it!

I will try some clay and soap and maybe something else another day.
 
I got lucky. Very first day I started working a current job, I jack knifed my bros trailer and bros trailer and broke a whole four quart jug of hydraulic fluid on the clients driveway. I got lucky as it was just a non maintained 3/4 minus driveway. The owner saw right away but I already had a load of base on the way and her driveway became better.

Reggi is there a pic u posted of it?
