Keep in mund that the "oil" typically used in an oil burning steam locomotive is as heavy as it gets....as step or two up from tar. If you look it up, many of them, especially as used on the Union Pacific, needed a steam heater apparatus to make it flow it was so thick. I believe it was called "Bunker C." Unless you have specialized refining equipment, most of the "fuel oil" available would have no real use other than for burning, and weed control, I guess.
I'm thinking that the WDW staff would have stockpiled what virgin oil it could and would also have access to a large quantitiy of used motor oil that could be filtered for this purpose, given the sheer size of the Disney vehicle fleet.
If used, lightly filtered motor oil is useable, more could be sourced from abandoned gas/service stations throughout the Orlando area. Missions to guard tanker trucks or obtain tanker trucks from recycling facilities (like those at Safety-Kleen) could be adventures in themselves.
As far as the Monorails go, they are indeed fragile and are stored in a semi-hardened facility in the same building as the steam trains. With the runup to full nuclear war, I would imagine Monorail service would have been curtailed and the units placed in storage at the time of the TDM, if for no other reason than to cut electrical power useage.
