That doesn't sound possible, 510 miles on one tank of diesel and then 1/4 tank left. You have a super economic TD4. I want one of those!
 
Possible or not that's what I got
like I said it was under 1/4 level
the fuel light came on yesterday at 535 miles so well happy with mine.

:D

djewson, your figures are impressive. Is your Hippo in 2WD only or is it proper 4WD? What is your style of driving, light footed or enthusiastic on the throttle? Whats your tyres and what pressures do you run? All useful stuff as saving juice is a serious issue now. Thanks, Dave
 
I was getting around 34MPG in my L series. Last weekend I removed the Tunit II box. The fuel gauge must be stuck now, or its using no fuel, I get back to you on the figures I'm now getting but it might take a few weeks.
Further to this, the tank was not full when I removed the Tunit module. However I have now run the car down to the red line and the result was 420 miles and used 54.3 litres of juice. That works out as 35.16MPG average. This is not an improvement on the figures before the box was removed. Obviously fully refuelled (£67.69 poorer for the experience) and now attempting again from a full tank. Will report in a week or so.

Hi Dave,

Mine is proper 4WD, I'm not a maniac when I drive I suppose I am quite light footed (I got used to this driving style when I had my Audi TT as that was totally pants on fuel - 25-27MPG so tried to hold back a bit) though I don't hang about either, I think the synergy helps as you don't have to floor it every time you want to pull away.

As mines a FL Sport I have 18's on mine with Continental Sport 4x4 Tyres all running either 30 all round or 32 when we went to scotland with 4 adults and the suitcases.

I am quite impressed after only getting about 270 miles to a tank out of the TT that I can get double that nearly from this (Though the FL Tank is slightly bigger)

Other info I can think of is it was serviced very regularly by the last owner as they only did about 5000 miles per year so they had it done on time rather than mileage, it has had the crankcase breather changed for the new BMW version, EGR Bypass, and its has done 48,000 miles..

Cant think of anything else..

Filled up yesterday morning, drove 44 miles on the motorway & 82 miles on A roads.

Filled up at the same station using the same pump today & used excatly 14 litres of diesel.

Works out to 34 MPG so I guess about right
 
We found with the missuses old 1.8 that it absolutely guzzled on long trips on motorways - do the same journey on a-roads and it was really good! Odd, but I suppose with the tiny engine, it was probably under less strain and happier up and down the gears and being under 50mph.

I'd be happy to get that Fritz:cheer2:
 
My HSE Auto has been averaging 31mpg..... (7.1miles per litre :eek: )

Fitted BWM crankcase breather last week and just about to fill it and check again ;)
 
Can get about 38mpg on a steady motorway run @ about 68mph. Seems to be about 440 miles to a tank, has been getting better since its part rebuild 3k miles ago.

Thats for an L-Series with 142k on it. Thatll do.

Whats the code for this part please mate and did it fit easy as heard some stories of the part needing some adjustment to get it in. Many thanks Jase.
 
Mostly around town and some dual carriageway driving I'm getting 34 mpg.
Towing (50% motorway) I still got 26mpg.
Not bad I think for an 11 year old 3 door.
I'm expecting more on a long motorway run without the caravan........will report back.

Right, refueled last night. 404.3 miles, 300 on worn 195 Synchrones, about 80 on 215 off-road tyres and about 20 on brand new 195 Latitude cross. Used 51.38 litres, so that gives 35.77MPG. Reset the clock. Now lets see what these "fuel saving tyres" can do.
 
According to my best attempts at mathmatics I calculate that my 2001 ES with 137k miles is doing 36mpg (rounded up to the nearest whole number)...but then the engine is un-modified and I drive like an old woman...as I have been colourfully informed.
 
Completely standard 2004 Td4 SW, manual, 79,000 on the clock, fitted with Federal AT`s at 28 psi, average between 35-40 mpg, very light footed on the accelerator, not up and down the box all the time as she can easily pull from 20 mph in 4th, regularly self serviced.
 
We have not had the freelander long so brimmed it last Monday, courtesy of Tesco's 5p off a litre and have done 170 miles so far and brimmed again today. I squeezed 25 litres in so that works out at just over 31mpg.

That has been a mix of 60% town driving/quick motorway hop and the rest sat at 70 on a return trip to work. It has also been fairly well loaded up for quite a bit of those miles as doing a garden project at the minute and the freelander has been a god send getting everything to the tip and 30 deck boards, 120 bricks and 10 bags of cement from B&Q - not all at once of course :)

Its a 1.8 as well so didnt think that was too bad.
 
Just done an "official" mpg check on my std `04 Td4S, 5 door, manual.

Had a 200 mile round trip to the lakes keeping to a steady 70mph on the motorway, and the other 220 miles made up of local commuting, just given me a return of 37mpg, very happy with that.
