When I can get nigh on 40mpg from an old design, 3.0l automatic petrol on a long run, I'd hope on a similar run, you'd be well past 60

But you're not are you? That's an equivalent from the fuel cost. If the government increased the tax on LPG, like they did on diesel a few years back, you'd be getting what, 27mpg? Which is easily achievable on petrol.

I have managed 37mpg on a constant-ish motorway run over a tank, in France. Pre LPG days

That was the same year I managed an average of 32.5mpg over the entire holiday.

It wasn't quite a full tank, I filled it again as soon as light came on, after I'd done something like 540 miles on the tank.

When I worked it out at the time, it was 37mpg

Back in the real world you get 15 on gas more like it

........after I'd done something like 540 miles on the tank.

If I drive enthusiastically I can get the diesel range to drop as low as that.   

I don't get anywhere near that in the Omega for some reason, do you think something's wrong with it?

You're hard pressed to get 30mpg from the 3.2 at a constant motorway cruise

I can barley make it do 27mpg, on a 150 mile run to Wales.

POS engine.

I lack the discipline nowadays. My mpg has dropped since all the 'tards now try to get more mpg, and just get in the way. They've become more of a PITA than pikeys.

With the 3.0, I tend to get around 19-20mpg on gas, which I don't think is too bad given its not driven with any thought to economy

That surprises me, as I managed 30mpg in my 3.2 between just outside Tenby and Wheatley Asda, 4 up with luggauge, including some *cough* 70mph *cough* up the A34 in a fit of frustration.

But its nowhere near as economical as the 3.0, and marginally less powerful.  That's the penny pinching compromises on it

It's strange though, I've had four 3.2's (still have three) and there is a difference in MPG between them when doing the same journeys, all are well maintained (well no4 is a project so can't really compare yet). Also a 2.6 with G cams wasn't really much better on MPG against a 3.2 and it would never match the power delivery and effortless cruising of it's big brothers.

[Migv6 le Frog Fan]

My 3.2 does 23mpg. Almostalways on shortish journeys. Slightly better MPG than my 2.5 managed on the same routes.

So another note on the VW, the air-con is silent. Jump in the Omega on a warm day like today, even when parked in a multi-story (so in the shade) the fans blast up to 10,000 rpm and make a huge amount of noise. After about 5 mins the car does actually get cold, but there is always a blast of air sound, so I manually turn the fans down on the climate panel.

Jump in the VW, no sound of air blasting, I've not even left the car park and it's super cold in there.

Just advances in tech I guess, FatherT's XF is same, silent air-con, freezer like temps within seconds.

The system is ten years newer, and the air intake systems are now designed to be unobtrusive. Also, your pollen filter is now under the glove box rather than the scuttle...

It's sad to find this thread showing the end of the omegas...

I've had my omega 2.6 estate for 5 years. Bought her for 600 quids with an ELM might on. It was just the vaccum pipes that had been mixed up after a cambelt change...

Done 100 000 miles with her all over europe, using ethanol E85 in France at often less than 50 eurocent per litre (you just need to change the injectors for those of a Volvo 760 3litres engine and it does the trick, don't hesitate to ask me for more infos)...

Don't want to see her go... Was thinking of a Volvo XC90 petrol, using ethanol while in France and not using her much while in the uK. Mercedes estates are not very nice. I want a RWD or 4WD. Not much around really.

Now the old girl is playing tricks on me. Sometimes it just would not start. Wait 4 or 5 hrs wherever it has decided to spend a nap and it does start again... Maybe a sign that the time to scrap her has finaly come...

But then looking at what's around and the money spent for a car that will certainly require work and that I will not know as well as I now know the Omega I just feel I am keeping her... So just ordered new fuel pump and relays and crank sensor hoping she'll be running again for few years more...If only I could fit pre facelift seats instead of these horrible CDX cloth seats!

Thank you for this forum that has helped me so often...

POS Something wrong with my engine. 

FTFY. I used to get 27 MPG commuting on petrol in the 3.2 and  really had to hammer it to get below low 30's on a motorway run.

Even when I first got it, unless I just stuck to 65/75 I could not break 30mpg. Maybe my foot has caught a bit of the fatty admins bad habits.
