1.9 sx 51 plate 40 to 42 mpg driving fairly carefully. ie up to 70 but more often than not 55 to 60. Millers additive and Shell regular diesel.

I'm very tempted to try Millers but from your figures I can't see that it makes any difference
- have you recorded consumption before Millers?

No, up till now i've always used Millers. If i don't use it on my next long trip i will post the MPG.
Since diesel went above £1/litre, I've been adding cooking oil to the tank. 9 gallons of whatever diesel is cheapest plus 1 gallon of tesco cheapo cooking oil (ATM it's £7.99 for 10 litres). Now I'm doing regular trips along a local dual carriageway, about 20 miles each way & this 1:9 mix isn't affecting performance, still cruising at 70 with plenty left under the foot to get around idlers.
I've not noticed any reduction in mpg either, still 350 to the yellow light, 400 to the fill & normal fill is 41 litres plus 4.5 of cooking oil.

It's always been my belief that MPG quoted is achieved in a warehouse on a rolling road - so as soon as the wheels turn it's straight to 5th gear & a computer governs the speed (like cruise control).
Real world figures are different.
However, I also believe that a larger engine will be more fuel efficient than a smaller engine (in the same car).
Whenever I fill up, I start out with good intentions to get best MPG - then some chav hacks me off & have to show him what a real turbo does
So, 1.9td, 105hp. Best I can get is 400 miles to the fill - always about 10 gallons (45 - 46 litres).

As an update.
We recently had some local debate about lowering speed limits to 20 within the town & along many estate roads.
One guy wrote in to say that most cars can easily achieve 70+mpg through careful driving.
I asked him if he could substantiate this & he sent me links to Government tests.
Since then I have been trying hard to adjust my driving habits.
I generally keep to speed limits anyway, I just had to change the way I got there.
Gentle accelleration, road awareness/reading the road ahead so letting resistance slow me down & only using brakes if I have to. 30mph in 4th is possible, barely touching the accellerator & the car moves smoothly along at 1200rpm.
Trouble is, I still have some dual carriageway driving to do 3 or 4 times a week so 5th gear & 70mph - but now I don't push it hard to get to 70.
I'm finding with the 1:9 mix (veg oil and diesel) I'm now getting 450 miles from a fill rather than the 400 previously.
If I had the time, I would drive the dual carriageway at optimum speed (which is somewhere around 40mph) measured by driving along in 5th gear at lowest rpm without labouring the engine.
I note that in 5th gear at 70mph, the engine is running at almost 3000rpm - that's way too fast, it would have been better if Fiat had looked at the ratio in order to bring the rpm down at high speed (my old car used to run at just over 2000rpm in 5th at 70mph.

Or people don't to test condition driving
I've beaten all MPG figures on all Panda's Fiat have done, just not on a long run in my Stilo yet as I haven't tried, but suspect I could
It's all to do withdriving style also.

I'm sorry but I just can't drive the way the government or anyone else tells me to, it's too boring.
I'd rather spend a few pounds extra on Diesel and enjoy my driving.
Fiat's Diesel engine isn't meant to be driven like that, it produces peak power and peak torque at very high revs for a Diesel.
If you're driving like sloth on mogadons to save money then fair enough, but I can't do it...but if you're doing it to "save the planet :nutter:" then get a bicycle.
Lol @ sloth on mogadon.
Round here we have a lot of speed cameras & many unmarked police cars.
We also have many sets of traffic lights/crossings/roundabouts etc, all designed to slow the flow of traffic so I really don't mind taking things steady.
In fact, many's the time I get to the next set of lights as they are changing to green & I can simply keep rolling whilst those who like to put their foot down have to start off again - usually as I'm trundling past them.
They, then, boot it to the next set of lights & sit revving whilst I catch them up.
In fact, I find I'm enjoying driving so much more because I think there's a certain skill in trying to squeeze extra mpg around town - it's also as funny as heck when the tortoise catches the hare.
Of course, sometimes I'm feeling a little :devil: & I occasionally let the turbo take over.

This is a reply to a post on the first page and I am only now learning how to use the "Quote" button (can't get it to work now I am editing this post), so please forgive my incompetence here!

Sorry to disagree with you, but the 120 is "fundamentally" different as it has a 16 valve head, not the old 8 valve head like my 105.

panda mjet 1.3 I'm finding 60mpg is more likely than the 65 suggested on combined use. Thats without a stupid dpf and with not a lot of weight.... which thus isn't that great for the compromise of driving around in a shoebox.
I'm so sad that the Doblo 1.3 has the dfp engine, as with that discounted, the 1.9 having weak clutch (?).. means I'm back to the HDI 90 Berlingo as being a better long term bet. I so want a Doblo but I want to buy something with my head...

I normally get 40-45mpg mixed driving with heavy load. A few years ago trundled back with light load from Devon at 50 on the motorway and made 64mpg.
Now the mileage is higher I cannot get above 55mpg but normally carry too many tools to achieve this.
Ok and I drive like white van man

:yeahthat:
What he said. Mine's an '03.
I think the 1.3 is probably too small, except in the case of the new Multijet2, which gives fantastic power, and economy, and isn't available on the Doblo!!!!!!!

I would go with that - my 1.3 75bhp high roof is a waste of time in headwinds or to anyone in a rush. For me trundling around lanes and areas restricted in the main to 50mph or less it's ideal.
Trips down the motorway are hard work unless you tailgate the big ones and then 60 mpg is easy :devil:

my 2006 1.9 mjet 105 cargo has been remapped & it usually averages high 40s. it's on 49.4mpg at the mo. If i do a lot of 50-60mph A road driving the mpg increases. It drops to mid 40s if i'm doing long motorway journeys at constant 70-80mph.
My van always carries 3 key cutting machines, 2 big tool boxes full of spanners, , ratchets, sockets, general tools, laptop, diagnostics & key programming equipment, big leisure battery, 2 jacks, axel stands, all sorts of bolts, screws, elec connections, tubs of oil, antifreeze, brake fluid, & at least a couple of hundred car keys/remotes so it has quite a bit of weight in it
oh & as somebody mentioned using GPS to monitor speed. I have been using my tomtom as my speedo on the M62 near me that's had 50mph average speed cameras on there for months now. AS far as i'm aware there's still 10% leeway over the limit due to different calibration of vehicle speedos.
So i generally stick to 53mph with tomtom which shows as 60mph on my doblo speedo. Which usually sees me constantly in the 3rd lane passing everything.
I also had the satnav on my phone on the 1st few times to see what speed that showed. It was identical to tomtom. Been doing this for months, probably easily a year with no speeding ticket coming through. Even cruised passed police cars with no issues. My tomtom is also bang on to those signs that flash up your speed. If I do 50mph on my speedo it shows as about 46mph

Sorry to bring bad news to the GPS doubters.
GPS speed readout is as accurate as it gets in the motoring world!! Most car manufacturers calibrate their speedometers to read between 5 and 10% fast. I can only remember one car (of the hundreds of hire cars I used to drive) having a speedo that was within 2% of the GPS speed readout. But I cannot remember what car it was.
Bear in mind that the GPS system is principally for the use of the US Military Forces and it also gives super-accurate timing sources to many other satellite and terrestrial communications systems.
