My 2.0 16v, I have calculated is averaging 21MPG with combined town / a road driving. I know they're not the most economical, but this seems excessive.

I've cleaned out throttle body, all breathers are cleaned out, new plugs, fuel, air and oil filters done.

Any ideas welcome...

Only two things I can think of but you would get an error are

The air intake temp sensor and the lambda

Foot, lead, springs to mind.

My 2.2 averages 25 around town, fitted with auto box.
 Long journey, Scotland to Devon, averages 36 -38.

I have tried slip streaming old ladies on zimmer frames and the variety of British Racing Green Tractors that we have in my neck of the woods.

Could just need a good old fashioned service.

21mpg  

Something not right there for an average!! Driving to Nottingham in the Senny at very high speed, including several runs to high 3 figures, on the private runway... it averaged 26mpg...

My 2.2 did 35mpg average on the way back to Uni on Sunday (cruise set @ 80)

Getting any error codes?

Tyre pressure?

[TheBoy]

Any brake bind?

[DaveL]

No just a snapping sat nav called the other half.

Ok, no fauld codes, I've already checked all of this

Jacked up each corner, no brake bind obvious

Engine's had a damn good service..

And what do you take me for Tunnie?   I check my tyre pressures weekly

Just checking, I should do the 2.2 soon  

Problem like on the old car, leaking tank? Fuel leak maybe?

Having said that we had it running in my garage for ages, no obvious smell of petrol  :-/

Mine used to get 22 commuting with a heavy right foot.

Over 30 on a moderate run, high 20s at 80mph, and running on Shell it used to get 20mpg towing on the Somerset levels! (but 16 in Devon Cornwall)

On the 2.6 gauge says 14.xmpg filling up says over 16mpg. More economical towing on motorway than commuting!!!! So check at the pump not the MID

I need to richen it a bit I think to get the emmisions light out.

And

I must stop thrashing
I must stop thrashing
I must stop thrashing
I must stop thrashing
I must stop thrashing
I must stop thrashing

Oh stuff it they sound nice over 5000rpm

Anyway so your tyres pressures are OK, brakes OK, serviced, leads OK? driving OVER 50mph?

For economy keep it at mid to high 50s avoid acceleration and braking, and polish it!

Try Shell petrol as well, also run some injector cleaner through

You could do the axle and gearbox oils?

[Taxi_Driver]

Carnt remember if its auto or manual......

Manual then id say its definately thirsty.....

My 2.2 averages 20ish on lpg......and i boot mine most of the time.....i have too....its a bit lacking on power.

[Martin_1962]

His is an auto

[JamesV6CDX]

My checks are based on calculations at the pump, rather than the MID.

Can't always keep over 50 in the town   but otherwise yes!

[theolodian]

If no DTC's then it may be coolant sensor problem, staying in warm-up enrichment.  Dunno about 4cyls, but different sensors for ECU and dash on V6.

Ah rite....cheers  

I would agree with davel then......25mpg av is probably about rite for an auto
