2003 Clio 1.2 16v.. very fuel thirsty. Just been serviced!

[alexemorris]

I had my car serviced recently in the hope that it make take the MPG up from 34.4mpg to somewhere in the 40s like other people have been quoting. As it is it rose to a meager 34.5 and I think that is down to the new tyre pressure. It had an oil change and just 2 weeks ago the clutch was replaced.

Getting an extra 10 miles out of every 4.5 litres of fuel would be a godsend as I'm almost broke after buying the car & insurance as it is! Any ideas, the best I've had is 35mpg and that was over a 10 mile journey home late at night where I was chilling to coldplays album and driving pretty slow.

You're never going to get 5mpg out of an oil change, unless you'd done 200k miles without changing the oil !

My guesses would be lamda sensor ? Blocked cat or binding brakes ? Get it to a garage you know and trust and get them to test emissions.

I get better MPG out of my 172 lol.

I get 42.6 MPG on standard petrol and i drive like a 17 year old! Which I am

I have a phs 2 182 with stage 1 tunning (190 bhp) and I am currently getting 36.4 mpg... sounds like a sensor to me... had a similar issue on my fiesta ZS (try cat sensor/lambda sensor)...

I'm going for either a lot of stop/start jurneys, lots of town driving or just booting it in 1st everywhere, just because you can.

Have you had the plugs and air filter replaced recently?

 

[montana]

yeah as camble said - plugs/air filter, fuel filter are good places to start as they are cheap to replace

 

[Camble]

can't replace the fuel filter on these, they're built into the tank iirc.

They only need replacing every 150k miles.

Are you using your aircon btw?

 

[KEVRSI]

its the lambda sensor or worst case you need a new cat
