Economics of using diesel

Now that diesel (1.32 per litre in the UK) is so much more expensive than petrol (1.18 per litre) is it more economical to use straight unleaded petrol in a steamer instead of 50/50?

Both fuels have similar Btu per unit weight but the greater density of diesel gives it more oomph per litre than petrol. At a certain point the price difference must wipe this out. Are we there yet? I appreciate that vaporiser length and perhaps jet size might have to be changed. Is there any other reason to prefer the mix of diesel/petrol to straight petrol?

We have a government which prefers to finance the country by taxation on fuel and as diesel vehicles become more economical (40mpUKgallon is about the average for the newest 3 litre cars) we must assume that the tax must go up to maintain revenue as less fuel is used.

It is probably easier to change a vaporiser than a government.
