Hi All,
The indicated average fuel consumption has just dropped dramatically on my 2.2 Auto petrol. It normally hovers sround 29mpg but yesterday dropped to 24mpg. I zeroed the reading to make sure.
Anyone have any idea what could cause this? I have a warning light (orange) that my garage says is a lambda sensor failure.

Highlighted - Erm... garage says? Did they give you any code number(s) for the fault / can you get the codes by any chance and post up here?
Any other work done / problems you've noticed as well as the consumption problem?
-
dont rely on the garage
is the eml showing,have you checked codes
lambda failure would illuminate the eml

Bloody wish mine said that, hovering at 21mpg at the moment.

Yes, need to get the codes read in full, before you go changing parts :y
I average 24mpg to 27mpg over the course of a tank in my 3.2, with 2.2 I could easily get 30mpg mixed driving over a tank.

just popped in to say i get 22 miles to the gall :'( on a good day lol it loves a drop of juice :P
-
15-18 mpg.

Hope you have a 3.2 & one of those god awful plastic boxes behind you on a tow bar & driving in town to get that kind of MPG :o

3.0 elite manual with thirsty mods. Yet I barely ever have the room to hit full throttle :(

Manual, even a 3.0 should be more than that. Even our local
Mr Angry certain Admin with his digital throttle pedal only achieves that on LPG!

Hmmm, yes, mine dropped suddently a few months ago from around 32 on motorway to 28. I reckon they've watered down the supermarket petrol!

Hi Tex.
As you can image we have alot of members saying they have taken their car to a garage and they say this and that, then actually find out the problem was nothing of the sort.
That said all garages are not rip off merchants, but sadly get tarred with the same brush.
If someone close to you has a code reader maybe a second opinion couls save you a few pounds.

I've got a 3.2 v6 and get 21 mpg on the motorway and 16 around town. I never put my foot down and am actually quite carefull, always looking at the current mpg to make sure i'm driving as economical as possible.

Wow! That's what my sister's partner gets in his Porche!

You have issues there, that's far too low.

My 3.2 does 18 mpg on short runs - 6 miles each way journey. Today on 200 miler up and down M40 averaged 30 overall for trip.
I was also starting to look into revs per minute - between diesel and petrol engines - but the torque vs horsepower theory was getting a bit much for me.
I was observing that the Phaeton (diesel) cruises at high speeds on low revs and returns 37mpg - the Omega is around 25% higher revs to maintain car at same speed.

Thats crap tbh :(
Looks like it needs a good service / looking at ;)
-
I dont know what mine is.. but it never lasts that long :'(
-
My 3.2 does 24 around town and 30 at 70mph on the motorway, I think that will do. My 1250 Hilman Avenger many moons ago only did 28 at 60mph ;D

The 1500 automatic I pulled out of my Avenger at the weekend struggled to make 25mpg, and topped out at about 80mph. If I could stand the racket.
I expect the XE that we bolted in it's place to do much better!
