Is the oil on the moon Titan made in a different way to the oil on Earth?

Can it be used the same way as oil from earth?

Titan is mostly covered with methane and ethane. On Earth, when discussing energy applications, that comes closest to natural gas, which is mostly methane with a bit of larger molecules. Petroleum, the black thick liquid, is comprised of larger hydrocarbon chains.
