1.4 16v stilio "poor MPG" 34mpg

Hi, just a quick one. I've had my Stilo for just over a month now and it's fine apart from a few things.
The big one is the terrible MPG
I used to own a 200bhp Honda Accord 2.4 vtec type-s and that gave me 33miles to the gallon, and that had to go because the fuel each month was crippling me.
The Stilo a small engine 1.4 is giving me 34mpg, im barely scraping 350 miles from a tank costing 70
Does this sound ok, I've had a look about and the stilo should be 42.4 mpg
The car is driven properly, eg not raced or ragged about. its a family car and daily commuter.
I've reviewed the service history and it looks good.
oil filter and oil done every year (shell helix+ 10/40)
but the last air filter change was dec 2008, not sure how many miles done since then.
Could an old filter cause such a drop in mpg, and chuggy idling and and up and down feeling from the revs when at idle and crawling along in traffic in 1st gear. Acceleration is a bit crappy too. very sluggish if you know what im getting at.
I'd like to get access to the air filter box but i cant get the bolts off, none of my tools fit. what size do i need to look for?

Re: 1.4 16v stilio "poor MPG" 34mpg

34 MPG sounds about right, especially if your driving it in a similar manner to a V-tec.

Expect about 40mpg on a very good run (55/60mph).

Re: 1.4 16v stilio "poor MPG" 34mpg

The stilo is driven in a completely different way to the type-S If i'd had known the tiny 1.4 was the same mpg as a beast of a 2.4 id have stuck with that..
Gonna try a new air filter, see if that makes a difference. Can i ask if any other 1.4 stilo owners get this mpg and 350 miles to a full tank just doing a 40 mile commute each day

Re: 1.4 16v stilio "poor MPG" 34mpg

I only get 33mpg from my 1.6, so not that much different to your 1.4. I have changed the air filter on mine, and despite the old one being very dirty it didn't make any noticeable difference. Funnily enough I have the same irregular tickover as you until the engine has warmed up. I did clean up the intake valve as suggested elsewhere on this site and it made a small improvement to the tickover but hasn't cured it, and made no difference to the mpg.

Well my 1.4 was on LPG, so a completly different kettle of fish, but for the 10 weeks I ran it on petrol before conversion, it was only about 34/35 I was getting.

Track a few tanks on fuelly.com and see where you end up would be my advise, and a good full service if not already done, which it sounds like it may not be if your asking about changing filters.

Re: 1.4 16v stilio "poor MPG" 34mpg

Our 1.4 regularly returns 42 mpg on mixed driving with up to 50 on decent long distant runs.
I would recommend changing the plugs and the air filter at each service. Check that the brakes are not binding. (the rear nearside brake has a tendency to stick)
You will have to change your driving style from the bigger engine you are used to . Dont be tempted to put it into 6th too early. On local driving we hardly ever go above 5th. Monitor your instant mpg with your driving style, and you may find you can save fuel by very small changes in foot pressure on the pedal without any real loss of power!

Re: 1.4 16v stilio "poor MPG" 34mpg

Thanks for the pointers, ive been out and had a poke about under the bonnet and worked out how to get access to the airbox, and sparks. will be a payday dayout to euro car parts for some plugs and filters.
I went from the accord to a Vx Zafira 1.8 and that was getting 23mpg then flogged that for a tidy profit and bought the citroen picasso 1.6hdi which was 48-50 mpg but the rest of it was crap and ended up a money pit so scrapped it after the turbo blew up and hydrauliced the engine, i then got the Stilo...
All breaks were serviced in june before the MOT, but I fancy some new pads/discs anyway as the standards are a bit vague in my opinion. I do like decent brakes on my motors..
will keep an eye on the figures

Re: 1.4 16v stilio "poor MPG" 34mpg

i was getting a good 42mpg up until recently, now its dropped to 36 with a loss of power also.

Today i really struggled to get 50 on a run. normally 50mpg is easy driving like a gran. i am going to change my airfilter as i think it may be blocked with mud dust as i drive across a field weekly.

Re: 1.4 16v stilio "poor MPG" 34mpg

just a quicky, what size spanner is needed to open up the front of the airbox. and also I was having a good look round the air intake and just after the opening
at the front of the bumper there is a box that doesn't seem to do anything. (ill put a pic later) what is it?
thanks

The box is a resinator (think thats what its called), stops unwanted unduction noise.

10mm for the airfilter housing iirc. Might be a 12mm though.

Not the bolts to move the resonator box, the 3 screws / bolts on the front so the front of the bo9x can flip down. look like 6mm

They're the ones I'm on about. Resinator box hasn't any bolts iirc.

How have you come to that conclusion. Its either a 90, in which case shifting 1300kg of metal is a lot of work for the engine, 120, which will use more juice anyway, or a 150 which most people will have a lead foot with. What MPG do you expect it to be doing

Re: 1.4 16v stilio "poor MPG" 34mpg

I'm with Cainy on this one - any modern small engined car (which his is ) should return far better than 38mpg. Likewise my 1.6 returning 33mpg is dismal in my opinion. My last car was a 1.9 diesel vectra and gave me an average 47mpg, and that's a far heavier and faster car than my Stilo. Even my 50 year old 1200 cc Triumph Herald (sold it three months ago) would do 35mpg, and that is as basic as an engine can be. I also have a 1.9 diesel motorhome which is like a huge brick cutting through the air and still gives me 25mpg even when fully loaded.

Not all Fiats are thirsty, I have owned a string of Uno and Punto petrol cars and they all had great fuel economy. My wife currently has a Fiat 500 1.3 diesel giving 63mpg - now that really is frugal (not that I expect the average car to get anywhere near that figure) but it still goes quicker than my petrol Stilo, especially on acceleration. She leaves my Stilo standing and she isn't heavy footed at all.
