Can you use motor oil to stain concrete?

Yes I buy 1 quart cans of pigment from our local hardware store and mix 5 gallons of used motor oil with half a can of pigment. The resulting paint rolls, spray or brushes on great but takes about a month to soak into the wood. Recommended only for use on unpainted wood since motor oil, by design, virtually never dries but will soak into bare or stained wood.
