The 2.5's I have had have always done 33-35mpg on motorway and a good 28 around town...

[martin12760460]

18 to20 mpg about right with me but i think i have alight foot  :-/

[cbowditch]

I get about 24mpg from my 3.0 MV6 auto on the daily commute with loads of stop/start traffic. On a motorway run at 65-70mph I can get 32mpg  [smiley=thumbsup.gif]

[motmann]

best i have seen on the MFD was 29 on a run back from cornwall in september more or less a constant 70mph with the cruise control on quite a lot! the worst was,well, dont want to talk about it but the MFD  showed an average speed of 80mph over 250 miles!!

[Tab]

my mfd reckons average about 26mpg at the moment, i get about 100 miles to £20.

does that sound about right? :-/

[motmann]

thats about right tab, my old 4pot auto was'nt great but the 3.0ltr hasnt proved to be the horror story on fuel that a lot of people reckon!

[albitz]

my 2.5 auto averaged 23.5 over the last year,i do a lot of short journeys though. i changed the oil last week and what came out of the filler neck could have kept hellmans supplied for a while!

I've found cruise has a slightly negative effect on economy, both cabled and dbw

I started a new job in November which requires lots of Motorway miles.

My 2002 3.2 MV6 will do:

36-37mpg at 60mph
33-34mpg at 70mph
31-32mpg at 80mph

For the previous 2 years I worked from home and did loads of short journeys which knocked it down to 23mpg.

I'm very happy with the motorway consumption, I hought I was gonna have to chop it in for a diesel but then our compny introduced a new mileage allowance that recognises bigger engined cars.  

I calculated I need to do 26mpg to break even so I'm easily doing that.

That's about what mine will do. If you can keep the speed down it is pretty good. Seems a bit of a waste though [smiley=evil.gif]

...... If you can keep the speed down .....

Which is why I tend to use cruise where & when I can. It helps to preserve my licience, as my speed would tend to creep up to near 3 figures without it.  :-?

Have a look at this spread sheet. It's data comes from OOF members who have contributed.

.......
Just don't look at instant consumption when you kick it down up a hill......

 ;DIt'll only get down to around 7mpg!

7.1mpg appears to be hard coded limit on both MID types I've 'really tested' on...

Ive wondered why i couldnt get my 2.2 to show less than 7.1mpg

Me too, Cruise has the habit of dropping down a gear & accelerating rapidly to restore the speed whereas a human would gently squeeze the throttle & resume speed gently thereby economising on fuel

An Omega's cruise is very gentle compared to a Senator, they really did want to restore your previous speed ASAP!
