See what the car is set up for.
Using better fuel than that will generally not help much.
Using worse fuel will hurt the mileage though.
We've got premium diesel here as well, but for me, the reduction in fuel used doesn't compensate the higher price.
If I want to have a shot at record low fuel consumption, I'll use it
In addition, not every car sees improvements in fuel economy when using the premium fuel.
