What plant would be good for phytoremediation on a large motor oil spill on my lawn?

i also need to know how to dispose of the plant after use?What plant would be good for phytoremediation on a large motor oil spill on my lawn?
I know willows are being used for this purpose, I think it takes several years to completely clean the soil but the state is using this method on a toxic spill in our area. Oil will also evaporate if the soil is dug up, and spread out in a 6'; thick layer, according to a friend that used to work detoxifying old gas stations.
