What speed do you drive at to get 40mpg?  

Best I've ever got was about 32, and I was delighted with that.

my Pug 605 3.0 V6 would do a lot more MPG at 90 than it would at 60.

Unfortunately, same doesn't apply on the Omega - slower speeds see better returns. Between 65-70 is most efficient in a V6, IMHO.

Constant 75. I do stretches of about 60 miles at a time. But I do find if I come off cruise and wander up to 80-85 it does not make too much difference - drops to maybe 37-38...

I managed to get 40 mpg only with a 4 pot 980 Kg clit  :-/

You must be going downhill with a tailwind all the time!!! I cruise at an indicated 75 (actually 72) and normally get low to mid 30's on a run!!!

75-80 seems to suit my car best, and I leave it on cruise control because otherwise it goes to fast - nothing to do with me   - it just wants to go faster.  I can't say if it uses less petrol at 65-70 - never really considered driving at that speed  .

But my impression is that there's not a great deal of difference in the consumption between 50 and 90 - neither of which I do for extended periods if I can help it.

What's truly horrendous is the 17mpg I get if I just use the car for commuting 3 miles twice a day  .

Thats because the pug engine has a shite inlet setup and no low down torque so it needs revving to get to an efficient point in the engines operating range!

Cats bolts are easy to get at...you can jack up the car high enough using the standard Omega jack...jacks up higher than a trolley jack...2 16mm bolts holding cats in place although people put different sizes on sometimes just to be bloody awkward!! Need some extension bars long and a short one combined...16mm socket also happens to be the 10mm spark plug socket and is ideal for getting up to the nut head over the bolt sticking out...

i don't go by speed, i watch the revs.....

at 2800 rpm (75 mph) i can get 35 mpg 3000 rpm (79 mph) its down to 32 mpg and at 3200 (81 mph) i am down to 29/30 mpg

Take it its not an auto then

You're getting 40mpg?  

I've just been to Devon and back - averaged 29.3 on a steady run!

Yes, 40!! I used to get 30-31 on the motorway and then it would drop to around 23 when I hit town. I've done a lot of work getting things fixed and a couple of weeks ago changed the cam cover gaskets as the plugs were drowning. MarksDTM changed the fuel filter for me because I didn't have the special tool. Now I get 40 on the motorway, and it drops to 35 around town

I have never, ever managed to get a consistent 40mpg out of a 3.0.

I've done it in a 2.5 driving like miss Daisy - but never in a 3.0!!

Have you tried this... get to 75 and hold it on cruise, then reset the Ave mpg counter?

I have no idea how you get them MPG readings... Has your car got the wrong MID screen fitted?  

If I reset mine at 75, it does 34mpg. Due to schools starting, my cars mpg from home to work (about 3-4 miles) is now 15mpg on a good day   (have seen 12mpg before door to door )

Next week I'll measure it against distance to get a 2nd reading and I'll let you know

Hell 40mpg (you must free wheel alot)   even on my bestist behaviour using a "featherlight touch " er mmm I cant get over 35mpg when watching readout on dash it says that when doing 50-60 mph but once over the 60' mark it drops considerably, are you sure some neighbour isnt adding fuel to the tank for you like an old movie I saw with Walter Mathieu
