I got 28mpg out of my 3.2 other day on my run to London  ;D ;D

Manual or auto, a well serviced 4 potter should be able to crack 30mpg easily on long run.

Air filter been changed recently? Fuel filter? Oil changes?

Mine was doing 32mpg on the motorways at 70ish for 100 miles or so.

That dropped to 30ish on the way back home due to going a tad faster!  :y

Forgot to say, that was in a 3.0 Auto, so I would expect 35ish in a 2.0 IMO.

oh.. i see! could the lower mpg have anything to do with engine management light for crank shaft sensor....

also i think baffles have gone in the exhaust.. that might not be helping...

Yes and yes, to both of those.. especially the latter, I suspect.

Oh and ignore Tunnie's mpg, he drives like your grandmother. ;)

What you have to remember is a lot of the people here, ermmm how shall I put this.... carry extra "ballast" - They also have digital throttles fitted, its either "on" of "off"  ;D ;D ;D

Seriously though i get 25-28mpg usually out my 3.2 & 30-34 out of my 2.2

Sounds like it needs a good service!  :y :y

To make a significant advance on the 1800kg kerb weight of the car through body mass would be a real feat of dedication, IMHO. ;D

Well if I got down to my 'ideal' weight, I'd make a .. 5% dent in it  :-[ :-[

Full Service it is then! just looked at the book, it was last stamped @ 69k (by vauxhall) but have got invoices for filters and oil which was brought last year so think its been serviced since the last stamp!

A good service is a must. Stupidly, I didn't realise how important this was!

However, I also think driving style is a lot to do with it. On long runs cruising at 70 seems to give me very good economy figures even if I decide to accelerate further to 95** for a while.

However, around town you really have to employ a ''smooth'' and careful driving style. If you decide to go a bit loopy*** round town and accelerate hard and brake at lights constantly you will really see your Omega dine directly from your current account!  :y

**the speed limit was only ever exceeded on my friend's private test track. I have never exceeded the speed limit on public roads

***the comment is not suggesting the OP has the potential to turn loopy in any way

Should be a little better than that even though you say it's an auto.

Best ever in our manual 2.0 over a full tank was just under 38mpg average: http://www.omegaowners.com/forum/index.php?topic=43828.msg659559#msg659559

28mpg for a 4-cylinder auto is quite good.
