I drive a 07 GPS Diesel, and never seem to get amazing MPGs from her!

I travel 5 miles to work each day, with the occasional 20 mile trip up the A1.
Trip computer seems to be constantly stuck at 35.5mpg, travelled up to birmingham at the weekend and the average rose to 38 (I know I should have reset the trip computer before the drive to get a better figure but forgot)
I dont drive with lead boots.

Ive cleaned the EGR valve twice, no warnings on dash, presume performance is fine, never been in another GPS (happy to accept an offer if anyone is around Hertfordshire)

Can anyone offer any suggestions/solutions to the problem, or do I just need to drive further distances to see any benefits?:idea:

Thanks

Clio 197 won't get a great mpg but that's because it's a hot hatch and to be expected where as the GPS 1.9 should be getting 45+.

Yeah I know, but the short journeys arent going to kill me on fuel!

Back onto Fiats!
Any ideas about the stupidly low MPGs, bar the short journeys?
 
Iv got a Punto but petrol and mine seems to get around 30-35 in the winter untill it warms up then i get about 42mpg average at 70 dont no if theres a connection with yours been diesel but with you only doing sortish stint and the winter wont help.
 
Your fuel consumption is typical of the breed, I get the same in town, I've even seen 28mpg once! mid 30s mpg is normal for the driving you are doing, hence the consensus that petrol works out cheaper in town driving. Motorway driving at 70-80 mph should give 45-50mpg over a distance of more than 50 miles, this is where diesel is superior to petrol. I don't want to sound patronising, but I feel you chose the wrong engine for your car, given the amount of miles you are doing I feel you would be better off with a T-Jet. No offence, just my thoughts on the subject matter.

Thanks for your reply, the low mpgs isn't an issue in terms of money on fuel, just thought I might be getting more. Used to do a lot of high mileage driving, but not anymore.(anyone fancy a swap? Haha)
No problems with the car atall. Just thought there might be a underlying issue.

Thanks for the input guys.

I get about 36.5 on a similar journey so as others have said it is about right. Hoped for a bit more bit it is still 10+ mpg more than my Punto HGT gave me.
 
These figures are crazy! Ive had mine nearly 3 week now and not seen it go below 39mpg and that was only once. In a morning i do a 8 mile journey to work where it only just gets up to temperature and it will do 43mpg all day long.

Once warmed up its even better!

what was you doing 30 in second all the way?
 
At the moment you are using winter diesal, this has additives in it to stop it waxing in very cold weather, once the summer is back your comsumption will rise.

In the summer i was getting 39-41 mpg on short runs now this is down to 36-38 mpg. Also in the winter the engine block is colder and takes longer to warm up so you use more fuel. I have just stopped looking at my average mpg to depressing.

hope this helps.
 
yeh true haha i had a saxo 1.1i before my punto and its fair to say if you wanted to speed up it took an age! lol

I would change the egr valve - cleaning does not always work and you dont usually get any warnings.
You should be getting at least mid forties.

I never get less than that now around town. Motorways close to 50mpg average.
I have had my gp nearly 5 years now and have cleaned and changed the egr numerous times and it is amazing the difference it will make when a new one goes on - it has always improved the fuel consumption by close to 10 mpg.

The problem is you do not notice it is dropping away but i am very aware of the symtoms now.

If you search i have posted lots of stats on this over the years.
