I don't have any specific figures, but suffice to say and reiterate that transporting finished products by pipeline over long land distances is less economically efficient than shipping crude. Yes, when you ship it long distances, some additional refining is again required to ensure the product is fit for its purpose and provides the kind of performance that it's required for, both in terms of regulated and legislated standards, as well as what consumers expect.
