I know this topic has prob been done to death, but...

Fuel consumption.

Now, as you can see from my profile, we've got a 52-plate 3.2 MV6 (ex plod - hence manual).  It's got 125k under it's belt.

Before we got it, looking at Parkers on t'internet, it said that avg mpg is 24mpg for an auto (no manual listed).  So, I thought at best I'd expect 26 - 27mpg out of it, on account of it being a manual.

But, when I've checked it's consumption since we've had it, its averaged 32mpg - and thats doing a mix of motorway driving, and being stuck in city-centre traffic (and I'm not that light with my right foot either).

My missus has got a P-plate 1.3 Fiesta with 90k on it, and doing similar journeys gets 35mpg.

I know it's not a like-for-like comparison - the Omega is obviously much higher-geared than the Fiesta which makes for more economical cruising on the motorway, but it's also got plenty of grunt at lower-speeds - I can sink the Omega into 5th at 25mph.

For the sake on 3mpg difference, I know what I'd sooner be driving - and it don't have a blue oval and a rattley camshaft on it!    And I think I could get better mpg out of the Omega if I was a bit more careful with the right pedal (like showing beemer drivers who's boss at the lights from time to time   )

So, after this long ramble - what kind of mpg are you guys getting?

[IrmscherKris]

Out of my 3ltr MV6 I got 22 right up to 32 (mway @ 56mph)

It was chipped and decatted though mind...

oooooooh careful, belt should have been changed at 40k

Aye, it has - at 40k, then 80k, then 120k - I got me GCSE in Maths (against all odds) I'll have ye know!  

[Kevin Wood]

My 3.2 auto MV6 averages about 27 or 28 on my normal commute. That's a mix of urban driving and "A"roads, and fairly gentle with the occasional hoon to the red line .

Motorway cruising at 65/70 it has averaged 36 over 100 miles. Up the cruising speed to 80 and it's probably down to 30, perhaps 32.

It is thirsty in very dense urban traffic, as a heavy car with an auto box will be.  Those are the journeys when you want a Ford Fester

So, add a couple of MPG for the manual box (especially in urban driving. once the torque converter is locked up the auto probably doesn't make much odds) and it's looking comparable.

On the motorway I cruise at - ahem, 70mph - I never go over that, not even up to - ahem, 85 to 90mph...  

[Kevin Wood]

Well, I only do on my holidays abroad, of course!

As I found out this summer, the really telling thing about these cars is how nicely they cruise at 120 on the autobahn with the cruise control on. Fuel consumption aint that spectacular then, though

Kevin

[damon80]

Well, on the autobahn was where we were this summer, but that was in the old Jeep, powered by Dr Diesel's invention, with shed in tow...

We're planning on doing the same next summer, but tenting and hotelling (if that's a word...) it - over there.

I'm just now, as I type, digging out the receipt from my last fill-up (I keep em all, writing the miles what I've done on the back of em - I'm sad like that!     )

[Kevin Wood]

That's the way to do it.   Went down to Italy and back this summer.

Kevin
  

[damon80]

We're planning on going to eye-tie land next year too - to venice.
Where did you go in Italy?

[damon80]

Right, got my last receipt.  Here goes...

I got 42.06 Litres, at 98.9p a Litre (why's it alway .9 at the end??   )

Which, dividing by 4.54, is 9.45 gallons.

I did 307 miles to that, which works out as:

32.48mpg

[JamesV6CDX]

That's bloody good...

I get 18mpg on my commute, all A roads and dual carraige way!

[damon80]

What's in yours James - an auto box?

How did the interview for the new job go btw?

[JamesV6CDX]

Mine is a 2.5 manual. 18mpg is hammering it, which I regularly do on the way to work! It will see 30+ mpg on a run. although, my 3.0 manual was better on fuel.

The interviews went well, and I passed the exams. I just need to wait now!

[damon80]

Good man on the job front - I'm chuffed for you!  

But what you say about your 3.0 being better on the ol' motion lotion - thats what I meant when I started this thread.  My theory is you can have a smaller lump that doesn't neccessarily do more mpg than a bigger one (oooo err missus   )

[JamesV6CDX]

Out of all Omega's, the 2.5 V6 manual is the best mix of performance and economy ... but the bigger engines are still not bad

My 3.0 Auto project/shed did 34mpg coming back from Kent, and that's a dog !

[damon80]

Now that ain't bad going at all James!  

[GastronomicKleptomaniac]

 According to the trip computer, I've had 22.8mpg out of my 2.6 manual. But I have a heavy right foot, and I'm addicted to the sound of the V6...

 I've had 30-plus on a motorway run, steady 60-70mph, and it got me back from Brum (about 200 miles away) on £25's worth of juice...

[phil.p]

i've got a 98 2.5 auto estate which i run down to london every week to work and i get 32mpg on the way down and 35 on the return journey ,only being heavy footed when overtaking.
i also have a w reg bmw tourer 318i 1.9 and driving it exactly the same way there is no difference in the consumption .

[Martin_1962]

Worst 11 head wind towing hilly.


Best 27 on a 30 mile run through the new forest

My commute is a thrash, don't do many long runs without towing

Most holidays tend to end up with lots of short trips and narrow slow lanes

But you have two cylinders missing

[BazMV6]

When I first got my auto 3.0 MV6 just over a year ago I was getting somewhere between 27-28mpg - not too bad I thought.  But over that time it's dropped and dropped until now my average is little better than 23mpg.  And at £1/litre that doesn't take me far...  

So what's changed?  Well, new tyres all round, and a full geometry (thanks Tony!) means that I have more confidence that it'll actually go where I point it, so I admit that the right foot get used a little harder...  And my journey to work has changed from MK roundabouts to a90, er 70mph dash on the A43.  But even if I try really hard to drive "softly" - I can't seem to achieve the figures I once did...   :-/

When was the last time you cleaned out the throttle body and breathers?

Has it had regular oil changes i.e. 5K or less?

When was the last time the fuel filter changed?

Had a tech2 read the codes?

Marks DTM read the codes last week with Tech2 when he did the autobox upgrade (and climate and cruise enabled!) and returned no errors.  All other readings which Mark checked appeared normal.

Cleaned TB and breathers during the summer - breathers were clear but TB was kacked up.  Oil and filter was changed with vx fully synth at last service in March (11k ago).  Also this service changed plugs, air and fuel filter.

Any other ideas??  Could plug gaps need adjusting??  When I accelerate hard, does feel as though it is holding back.  Progress through the 'power band' is not smooth either, feels like there is a 'flat spot' present.

Any help would be much appreciated!!!

[Entwood]

Check exhausts ??  Several folks on the forum have reported exhaust pipe failures through "blocking up" .. I had it on mine when a load of hairy wadding came out the back ...  new exhausts went on and performance increased dramatically  

[TheBoy]

Oil and filter was changed with vx fully synth at last service in March (11k ago).

That is far too long. The specified oil changes are to please fleet managers, not look after the engine.  Nobody makes an automotive oil that lasts beyond about 7k, hence I normally recommend <5k oil changes.

Not that changing the oil will improve performance immediately, but a kind service schedule will slowly bring some performance back.

[ians]

Forget adjusting - if in doubt just change them.  Easy job and not much more than a fiver on TC.

Did you make sure to clean the small breather and its port just below the throttle body?  Made a huge difference on my 4 pot.

Will change the oil again this week - is it worth the extra for fully synthetic??  Probably worth another service for what the parts will cost whilst I'm at it!  The last service was two years previous (before I owned it) but only covered 5k between then and when I first owned it, so 'missed' at least an annual service, so you could say the car had been a little bit neglected!

not in my opinion.

My MV6 gets a fresh lot of Vx Semi Synth every 3 - 4k.

Trash a V6 and it will leave a 2.0 or 2.2 for dust, over a certain road altered figures where fastest is given 100 points (NOT mph)

2.0 81
2.6 98
3.0 100
2.0 H/C Carlton 86
1.6 Sunbeam 95

Another
2.0 88
2.6 98
3.0 100

BTW this is more fun because you don't know if I scaled up or down but Another was lower values

Oh if you can't get down to 20mpg on a 4 cylinder Omega you need to try harder!

[tunnie]

Oh if you can't get down to 20mpg on a 4 cylinder Omega you need to try harder!

i don't tow a burger van  
With lots of oil changes and proper maintenance  my 2.2 has come on leaps and bounds.

I then drove a 2.5 manual... i felt hardly any difference.

I much, much, MUCH prefer working on the 2.2 for engine maintenance, its just so easy to work on.

I just don't like the V6 engine.

This was back road thrashing, van got it down to 17mpg - and I think the 2.0 has now been scrapped (not on tax or insurance registers ).

If you can't get a car down to 20mpg either you are too slow or the car is

[omegadan2.2i]

Update on fuel consumption on my 2.2 auto (filled up today) - this has been the WORST consumption so far for my usual weekly running:

MID reading:  Ave. Speed: 26mph  Miles covered:  270.1  Miles left:  76  Ave. Cons 23.4mpg!!!  

Bought plugs, air filter oil and filter to change this week.  If anyone can PLEASE help me to sort this out to achieve 'normal' fuel consumption this would be much appreciated!!!

Thanx

That was before cam timing was done, and MAF sensor replaced. Both of those made a huge difference - with the multiram working, it would be even better.

Still does not compute

My 2.5 has been well maintained - just that when you drove it, there was a duff MAF, and cam timing was out.

The 4 pots, while I really rate them as a good engine, they're not designed for speed / performance!

Hi, my driving is all urban, five miles to work and back mainly, twice a day(bloody split shifts!) It does't seem to matter how I drive it, very gentle or heavy right boot, I can never get better than 19.4mpg. Am moving soon to either the new Mondeo or a new Passat, in diesel auto spec. Should notice quite a difference in fuel consumption, but will be sorry to see the Omega go, won't know what to do with the weekends not having to lie under the old bus fixing it!

I suspected that this might be normal, has been the same for the two years I have owned the car, but only doing 6,000 miles a year approx I am have happily put up with it in exchange for the comfort and performance.
