#1: Fuel economy Miles Per Gallon 206 1.4 petrol Mk1 Author: GreenTrees, Location: Portsmouth UKPosted: Sun Jan 09, 2011 2:20 pm ---- Hi,
We are getting a lousy 32mpg from my wifes V reg 1.4 petrol. She's no racer, and I am wondering what can be done.
So far I've gapped & changed the plugs, added some "injector cleaner", adjusted the tappets (they were a little noisy) and recently pumped the tyres up a bit more (still awaiting the mpg figures from that change).
Any ideas would be most welcome, oh and thank you for reading my 1st post !

They drink like a b***h, its just the way TU engines are

Denser air is better for an engine though, they perform better, so surely it will go up?
As the thinner the air the more the engine will need to work

Then of course on the motorway i can normally expect 45-50mpg.
You said you changed the plugs but when was it last fully serviced oil and filter's etc?

Denser air means more fuel

Denser air means more fuel
Shush
Im just thinking of theories, as less air means the engine has to work harder, meaning it needs to draw in twice as much air to match the performance of the winter?
Btw shell fuel saver fuel is crap
#8: Re: Fuel economy Miles Per Gallon 206 1.4 petrol Mk1 Author: Andrew, Location: Black Country Ay IPosted: Sun Jan 09, 2011 2:38 pm ---- I use V-Power because I reckon the 99 RON fuel has to be better for the engine's life span than regular
Denser air is more power because there is a bigger explosion per full cycle in the cylinder, but because the air is thicker more fuel is injected to keep the same air to fuel ratio
To the OP, that isn't really bad, as Addaz said all the TUs are like that, you'll notice it might slightly go up in the summer

hehe the car performs normal in warm air which gives good mpg because it doesnt need as much fuel as when in cold air where its more dense it will need more fuel
Ive noticed mine has dropped from 30mpg to 27mpg over the winter
Shell V-Power FTW anyway

#11: Re: Fuel economy Miles Per Gallon 206 1.4 petrol Mk1 Author: Mike, Posted: Sun Jan 09, 2011 3:03 pm ---- My 1.4 is ridiculously thirsty! Doesn't hep though I only do 10 miles a day driving so it barely gets warm and it's got to work/got home

#14: Re: Fuel economy Miles Per Gallon 206 1.4 petrol Mk1 Author: GreenTrees, Location: Portsmouth UKPosted: Sun Jan 09, 2011 3:50 pm ---- Surely it's not "normal" is it ??? It's my wife's car, my Y reg Avensis 1.8 vvti estate does better @ 35mpg despite the density of the air ! We both do mainly local runs.
Oh, I should have also said... I did an oil / filter change & changed the air filter too, this 206 has done just over 70kmiles.

There's nothing wrong with it, that's what a TU3 powered 206 will do average mpg driven around town
