Which is surely the reason Diesel used to be cheaper, because it provided better economy you were 'rewarded' by paying less for it. When a lot more started using it, the price rose dramatically to the point where it is now more expensive.
No matter what the fuel is, they will get money out of you. It will start off with an incentive which then gets taken away. E.g selling energy back to the grid, they have already changed the rebate amount because of the amount of people doing it.
