I want to know if there is any substance, liquid or any other stuff to separate ferrofluid from oil after mixing them.

Typical ferrofluids are suspension of nano-sized magnetic particles in oil. If you add more of the same oil and mix thoroughly, separation is impossible.

If you add a chemically different oil, you might be able to remove this compound from the mixture again by distillation in vacuum.

You might be able to recover the magnetic particles by extraction with a suitable solvent (thinking of petroleum ether or hexanes) in order to get rid of the oil. A frit might come handy.
