ive got a 2001 mk2 mondeo zetec s and the fuel consuption is really bad 18 mpg its done 160,000 miles not long had it just moted it emissions perfect not leaking fuel has anyone got an idea where all the fuels going thanks rob

 

Rob when was it last serviced? A good service usually helps MPG, Is this motorway miles or town driving?

 

Thats shocking!! Pre cat lambda sluggish?

 

Lambda should be fine if it's just been M.O.T'd and the emissions were perfect. I would try new oil, filter, plugs, fuel filter etc. Also try some fuel cleaner through it this usually helps to.

 

ok will try good service i think its mainly done town driving ex taxi only thing i can see wrong is temp gauge going up and down plugged laptop in no stored codes or problems hopefully good service sorts it thanks guys

 

If it were using that much fuel as in burning it, rather than losing it for example, a service is not going to correct the issue, but certainly can't hurt, does it drive ok, no hesitation or anything ?

it does seem a little bit flat but its done 160000 picks up ok and still goes good after 4000 revs

 

2001?
mk2?

it should be a mk3 and i would suspect the flaps in the inlet manifold are causing the problem

do they rattle?

 

i've got a 2.0 2000 plate mk2 Mondy and fuel consumption isnt great either, think it could be due a service mind you but i put it down to fuel prices

 

mine does about 18 mpg in town and about 34 on the motorway

but it is an auto

i reset all the meters when it went for an mot and when it came out it had done 16 mpg and averaged 1 mph

 

It is possible, Theres 2 mk2s near me on 51 plates

 

Seeing as the mk3 started on an X plate, that just means they've had cars unregistered laying about in a field somewhere

 

Indeed! My t reg mondeo wasnt registered till 9 months from its build date and my 02 plate fiesta was sat round for 14 months from its build date before being registered. Good call with the flaps in the engine though

 

Do Mk2's even have the inlet flaps?

I thought they were just MK3 Duratec engines that had them?

You have checked for sticky brake calipers etc?

 

dont have flaps on mk2 black top brakes are not sticking on done service today hopefully sorts it or ill have to start selling my arse to pay fuel bills
