There is a lot of discussions going on between the guys with management cars, all HSE's who change theirs every three months. The latest batch do seem to have a lower MPG, around 25-27, could be the build and parts making the individual differences....

Could be they are not quite run in denny... post 1st service the D3 does indeed increase its MPG figure. MY2008 is much better at sipping diesel than previous MY's were.

As an experiment for a couple of days I tried the TopGear TopTip - & switched off the aircon, front, rear, & the cubby cooler. Result - mpg rose from 27.4 to 30.9, not bad. And thats pretty much for same journeys, same speeds etc.
Worth bearing in mind until of course the great British summer actually arrives. I liked my D2, but my D3's better ....

I don't use the air con unless it's a hot day, rarely use the cubby cooler, and have experimentally driven like a fanny to try and raise my mpg. Never been higher than 24.7. Have MTR's on, but mpg was still the same with oe tyres. Don't think anything other than a TorqTune will help, so will have to get that organised.!  Don't be paranoid.........'They' don't like it!!!!!!!

Climate control always on, cubby cooler always on, MTRs always on, averaged 29.8MPG over the last 14,000 miles    
Not so common...

I too have tried Slick 50 - some years ago on petrol engined vehicles....unless you are doing repeat journeys that are comparable periods its difficult to gauge improvement or detriment if any I got little or no advantage in either MPG or performance.
Its a bit like the "KIng's invisible Clothes" - imaginary
At first I took the claims Slick 50 made as viable.....but I now doubt the ability of this additive to adhere Teflon to any metal surface....If you have worked on industrial Teflon coating process the first requisite is the metal surfaces are scrupulously clean & oil free. In those days there were others with similar claims Rocol had an additive with molybdenum di-sulphide, STP claimed to modify the nature of oil & reduce oil consumption (it was like adding treacle), Wynn's did similar products. BP even launched special oils with a viscosity intended to save fuel....it may my Volvo 240 B21E engine sound like a bag of spanners & was very quickly refilled by the dealers doing the service supporting the warranty.
Other products have appeared from other countries Nulon from Australia, MotorUp from the states....the way these products were sold - direct TV advertising demonstrated the incredible claims in a series of stunts - engines run drained of oil etc.
I would agree with other who have written in this thread that if Slick50 claims were viable it would be a component of regular motor oil....you can get the same effect by using a good quality synthetic lubricant as per the oil specification for the TDV6 engine. You gauge the long term effect in the longevity of the engine.......burning oil, compressions & destruction of camshafts & turbochargers. You pay your money & take your choice. ....have Disco3 HSE TD6 Auto...
....also S Type 2.7 Auto....

I too tried this, and was suprised to find no apparent difference whatsoever. I unplugged all accessory sockets, aircon off (not just economy) and yet it paid no dividends. On the plus side that means I can keep the aircon on full time and it won't cost me anything, being apparently powered by some mystical perpetual energy source  Give a man a fire and he's warm for the day. But set fire to him and he's warm for the rest of his life.

Well, after telling all & sundry about this I turned everything back on last night on the way home - MPG stayed at 30+
It is perishing at the mo though, maybe the aircon don't work so hard when its cold. (but I don't think so).
More welly needed. MPG thingy now turned off. I liked my D2, but my D3's better ....

if you have a good look this subject was done to death a while ago.....water steam injection there were some early systems (60's 70's) some recent new technology similar systems are on sale but not mainstream acceptance or take up
Interesting website & links......thanks for those ....have Disco3 HSE TD6 Auto...

I think the whole D3 engine and drive train system along with the aircon system were design together and thus the actual drain on power is kept at a minimum.
I think 
I too have noticed absolutely no benefit in running the system in the ECON setting.
The only sure fire way to save fuel in the D3 AFAIK is to use a gentle throttle, stay below 75MPH (where legal of course) and NOT use cruise control... use your senses to keep the power just right. Also utilise the torque band at around 1800 to 2500 revs. Cruise at 2K revs and your range goes up as the trip goes up
