Does anyone know how to remove oil from a tarmac driveway?

One of our cars must've leaked oil on the driveway and it looks terrible now with a big patch on it. Anyone any idea how we can remove it?

There is cleaners specially for the job.

You will get it in woddies , b&q and i presume most diy shops.

Have you tried a power hose?

It may not work but i know when we had a similiar problem from our central heating burner and the oil (over years of drips) had made a fairly extensive stain on the path at the back of the house.
the powerhose was able to do a fairly decent job of it.
(could be a cheap and cheerful option if you have one or can get a lend of one)
