Well if it is motorway driving you can get to around 34/35 mpg top end.
Around town you are lucky to see 19 mpg, and on average I see about 21 mpg.
So with a tank holding 75 litres you can work out the average range you will get.
Oh yes, and I am a fast driver using the S mode & box to the full! 8-) 8-) 8-)
-
You get 21mpg with Smode ON and your foot planted! Thats pretty good!

In town though I do use the accelerator economically, in others words when I accelerate I try to make the most out of that burst of energy before using my brakes, and always obeying the speed limits.
On motorways and out of town roads then I use the car to the full ;) ;) ;)

According to my on board computer I get 21.5 mpg commuting to work (mainly town driving). However, when I calculate my mpg based on odometer mileage and fuel used (from last full tank to re-fill amount in litres) it works out at between 18 to 19 mpg so dont trust your on board computer to be exact :P. On a motorway run I have achieved 30mpg (calculated). But like you say driving styles will come into it. I don't think it's worth having the power if you're not going to use it. :y

mine took 40litres to do 300miles on motorway
birmingham-edinburgh
i think i get around 85-90 miles to £20 of fuel around town

The trip computer in my 3.0 auto saloon is currently showing 18.5 m.p.g. but I only normally do very short runs so the car never really warms up properly, as soon as the temperature gauge hits half way though I tend to drive every where with the rear end squirming and my foot buried deep in the carpet!
-
i believe theres alot of heavy footing going around lol i think im getting simular miles but i do tend u put my foot down abit but i took my car to have the emission test and it fail the test aswell but i cant say i notice on the fuel i donr surpose anyone knows why the emissions would fail ?
take care

I drive fairly "Grandpa" like and have NEVER had less than 25 mpg on average, on a 50/50 combination of dual carriageway and around town.
I've always ensured the breathers are clean AND had EVERY gasket and ring replaced a while back.
That said and I'm sorry to any doubters out there...but as with every car I've ever owned I've used Slick 50 in her, and every car I've ever owned has always appeared to give me better fuel economy that expected. Either that or i'm more of a Grandpa than i thought ??

You're injectors need cleaning then.
The fuel computer uses the injector duration to work out the fuel used. It should be very accurate and if yours isn't then the injectors are letting in more fuel than they should - which will be caught by the lambda but only after it has happened. Also, lambda is ignored under acceleration (except if very mild).

Most likely faulty lambda sensors but could also be cats or leaking exhaust. I'd have thought your emissions tester would be able to point you in the right direction.

Min 480, max 500 miles to a 3.0 estate tank on motorway miles, 380-400 if mostly town miles.

Dirty injectors :-[ What's the best (easiest) way to clean my injectors then? Any recommendations? :y
-
Min 480, max 500 miles to a 3.0 estate tank
The best i have ever seen in my 2.2 petrol was 37 mpg and that was driving like a fairy on a motorway run ... i got 420 miles out of that tank .
I know the 2.2 is not the most economical :-/
I wish i could get 500 miles from a tank and yours is a 3 ltr .
:-/ :-/

You can try the stuff you add to the petrol but the only way I've found that really works is to have them cleaned ultrasonically - that way they get tested too.
Some places do an exchange scheme where they send you cleaned injectors and you pay a deposit that is refunded when you return your dirty ones. The idea being you're not without the car while they're being cleaned. Or buy a spare set and send them away.
What's your mileage?

constant 30-34mpg average over course of 4 years, can't complain here, rather do that and get 38mpg in some crappy FWD hatch

Try running a BMW 540i then. My normal commute in the Carlton 24v GSi would get about 31-32mpg being frugal, or 27-28 if givin it some. In the BM I used to get 22mpg bring frugal and 17 if not.
I get about 28 in the MV6 auto regardless :-?
And about 32-33 in the manual if gentle on the gas or 28-29 if heavy.

i agree tunnie if yer gonna get shit mpg do it in style and comfort..but iirc most of your miles are motorway commuting so you will see alot better mpg than most
-
Oh, and BTW, 1998 E39 540i = 4.4L V8 (285bhp/324lbft) so it's maybe not surprising it drank fuel.

Used to get 30mpg average on my 10 mile commute that i did for 2 years, i don't find Omega consumption that bad
-
well i filled up my tank and im just under the 20 ltr mark and clocked 313 so far and that is mostly motorway and i dont drive mad and keep it at 70 most of the time ?
-
Hi i have been told when engine at temp, put computer on instant con it should read .2 if reading .3 its running rich .Make sure lights and heater is of
I get 19 to 27 around town motorway keeping speed about 65 to 70 mph i get 36 mpg, and thats withe a roof box on.
Put computer on instant and put your fut down then i get 7 mpg
-
hi ok i didnt know that il have a look
thanks :y

...

I'm not checking now, but IIRC mine normally ticks over at 0.3 gals/min as did my Senator. :-/

Depends if you've got the aircon running too.

A/C is almost always on 'auto' so it must be when it's ON
I'll take more notice next week when I use it everyday in sunny French France and report back ::) ::)
-
i dont mean to sound thik i got air con but i dont know how to turn it on there is an eco button what does that do a light comes on when pressed but nothing happens
thanks

Assuming all is as it should be, it knocks the a/c compressor off, which in effect reverts your car to a car without air conditioning. It would still heat if required,but obviously not cool to below outside air temp. :y
you could read the manual ::) ::) ::)
When you press 'AUTO', you've turned your air con on (does it still have enough gas in there? ;))
-
Does nowt when I press mine either. :(
Must get TG to ask his boss how much for a regas.
-
i was told ages ago when u switch on aircon the rev counter drops a tad putting more strain on the engine is that correct
thanks
-

No the ECU should speed up tick over to compensate for the compressor load.
-
oh right ok i just read in the manual regards to the eco it says when the aircon is in auto mode u press the eco to save on fuel ?
-
When you press eco it switches off the compressor, which takes a load off the engine and saves fuel, but you don't have aircon.

Hhmmm... lovely! Mind you, you can get an M5 from the same series for not much more these days!
-

Yep, and if it's auto you have to hold it back more on the brakes at junctions cos the extra revs make it want to "creep" quite a bit more. If find that a pain in the neck when trying to manouver into thight spaces.
-
well to add my twopennorth i get 32 on my hemel run from doncaster and back once a month and knocking about doncaster 25 im well pleased with mine better than the 2.5 i had and thats with the oil leak at the front i have to put up with but seriously its the best car ive had for fuel consuption and its a 3.2 but if we buy these cars we have to accept that the lovely and serene drive and the rush of power when needed as to be paid for
-
AND a price well worth paying as far as I'm concerned.
Mind you, at 40p per mile business use, fuel wise, it doesn't really cost me a penny. :y :y :y
-
Lucky you!!! I only get 20p per mile, just breaks even if I'm a bit light on the throttle, or on mototrways a lot. :-[
-

That's pants, tell them you want more or the company will need to provide transport. You're allowed up to 40p/mile before you can be taxed, or 45p/mile if you have one or more passengers.
40p doesn't really cover the true running costs of even the most frugal of cars - not when you add up insurance, tax, mot, tyres, servicing & repairs and fuel.
-
Just turned 28,000 miles (with full history). Has anyone else every done the calculation to check the accuracy of the on board computer. Method to clarify calc. Fill tank to full - reset odometer & onboard computer - run to almost empty - refill tank to full - record litres to refill - record odometer mileage - divide litres by 4.5 to convert to gallons - divide mileage covered by gallons to get mpg then compare with on board computer.
-
hmm... 16MPG stop start town work, i.e. Manchester, changes gear before 2,000 revs in an 3.0 MV6 Auto.
16MPG = Shite!
I am tempted to try that injector cleaner stuff but I doubt it works lol
-
only get about 20mpg out of my 3.2 but thats anaverage lpg calling!!!
-
It must be the way you or I drive them.
My Dad drives like the manager of mattress company and he always returns a better MPG than me and I have done advanced motoring courses and various other drivel.
