First, Weiss said that the Dust she brought was mined and PURIFIED from the Schnee quarry. Second, it's my headcanon that there are fortified Dust mines/quarries outside of the Kingdoms. So the whole argument of choosing Dust because it doesn't need to be refined is invalid. Also, to believe that all there Dust needs can be met even for now by deposits within their borders feels foolish.

I agree that Dust is far more potent and versatile than fossil fuels, and it can directly deliver usable energy instead of there being several steps. Why burn coal to heat to turn water into steam,to turn a turbine, to generate electricity when you can use lightning Dust? Or even steam Dust.

That said, petroleum has uses beyond combustion for power. Medicine, plastic, asphalt, oil for maintaining engines. I suspect they would still need to acquire petroleum, and different kinds offer different uses. Even once we stop using fossil fuels, we'll still need a fair amount of petroleum for our modern society.
