Some people have reported up to 10% using premium diesel, but that could be a bit optimistic, others use an additive like Millers Sport 4 to achieve similar results. You could try either, or both, of these at very little initial outlay and see what they do for you.
Even so, I don't think you are going to get 40mpg over a period of normal driving whatever you use. Personally, I think if you can average 36mpg over an extended period of time while driving normally you will be doing well. I've done 3000+ miles over the last 6 week using a variety of diesels, and I have tried the Millers, but I haven't achieved anywhere near 36mpg.
The other option is a tuning chip or ECU remap but I don't know how many mpg these could be worth.
i suppose it depends on what you call drive normally..
on my normal commute to work, I tend to dordle along in the inside lane doing 60mph... little point in going in the "get out my way, i'm in a rush" lane on the right.
It still takes me 40 minutes which ever lane i choose.

I think it was "5th gear" that did a recent review and test on super-diesels, the general consensus was that there wasn't much in it but you may gain very slightly overall. I think the major long-term benefit would be picked up by second and third owners, who will gain a cleaner engine, if all the advertising is to be believed. Only time will tell when engines are stripped for rebuilds in 15 to 20 years, but by then it'll be almost impossible to confirm what fuel it spent most of its life running on. Try it and see, if your "ar$e-dyno" tells you it's better and it pays for itself, then go for it.
If you want "much cheapness", go get a Hemi and gas it, lol. Cheaper to run than a CRuD and healthier for the environment too, with no carcinogenic soot being pumped out into the atmosphere every time you accelerate.

I wonder have they increased the road tax in Iraq and Afghanistan.
And charging a high price for renewal of taliban firearms certificates, LOL
And now that the truth's coming out about Global Warming being a total conspiracy con job by numerous governments. What will they do next?
